Prof. AL. Ramanathan has been working in the Indian Himalayas for over 18 years and developed a state-of-the-art glacier mass balance model, particularly for the western Himalayan glaciers. His work has been cited in the IPCC Fifth Assessment Report (AR5). The study shows that snow accumulation is the major driver for healthy glaciers and runoff. Summer snowfall has a high impact on glacier mass balance (MB) i.e. albedo-feedback mechanism. His work revealed that the glaciers at low elevations and smaller in size are retreating faster due to a decrease in annual precipitation and increase of mean annual temperature, driven by incoming solar radiation during summer that controls MB. He observed that the western Himalayan glacier‘s terminus is retreating but the shrinkage is discontinuous. The glacier dynamics and MB of his study revealed steady-state glacier conditions during 1986-2000 in the Lahaul-Spiti region as against the general perception of the rapidly shrinking of Himalayan glaciers. His study delineates the major sources and availability of the nutrients, Bio-Albedo & human impact on the eco-hydrological services, and biodiversity in mangroves, Himalayan Glaciers, streams, and lakes. N, P, Blue carbon sequestration, and metal biogeochemistry were studied to know their impact on their productivities and for better intervention to reduce it. Nitrogen and reactive nitrogen fluxes contributions in Indian mangroves were estimated to be very high compared to global flux. SW-GW interaction, Fluoride, Arsenic, U, NO3, etc., and their sources and mobilization in groundwaters were identified for its suitability for drinking, irrigation, etc. Proposer: Prof. Rajiiv Sinha, Seconder: Dr. M.Ravichnadran Ten Best Publications: 1. *Ramanathan, A L., Vaithiyanathan, P., Subramanian, V., & Das, B.

Dr. Kusumita Arora is a geophysicist with more than two decades of research experience. She has worked on various aspects of the Earth‘s geopotential fields: gravity and magnetism to address a wide variety of problems in basic and applied research. Starting with techniques of applying Terrain Correction for the updated Gravity Map Series of India, 2006 in absence of a homogeneous terrain database, she went on to develop a large scale 3D density model of the western continental margin of India based on gravity data. Her recent work to unravel the surface structural fabric in the Koyna-Warna region in India at sub-metre scale resolution using Airborne LiDAR remote sensing technology – a first in the country - has helped in illuminating pore pressure development conditions in three dimensions to explain patterns of triggered earthquakes. Dr. Kusumita has provided exemplary leadership in revitalizing and modernising magnetic observatories, including one at Maldives - in cooperation with ETH, Switzerland - and link them to the international network INTERMAGNET as well as expanding observations in the equatorial region of India over the last decade. These data have been the backbone of the research work carried out by her and her students on diverse angles of ionospheric and magnetospheric phenomena. In 2014 she brought close to a 100 participants from over 30 countries to India for an international workshop on geomagnetic observations. Her passion and open minded pursuit of scientific enquiry makes her an aptly suitable candidate worthy of an Academy Fellowship. Proposer: Dr. Archana Bhattacharyya, Seconder: Dr. R.K.

Prof. Parthasarathi Chakraborty has made unique and outstanding contributions in the field of Marine environmental geochemistry. His research has improved our understanding of metal-natural ligand interactions in coastal marine environments, and succeeded in revealing how metal-buffering action of natural ligands makes them a vital web in the complex fabric of homeostasis. Prof Chakraborty‘s research helps us in comprehending different microscopic geochemical processes that control metal biogeochemical cycling in coastal marine environments.Prof. Chakraborty developed kinetics-based approaches to understand metals speciation and their bioavailability in estuarine/coastal and deep sea systems. His research focusses on developing and applying a wide range of kinetic methods for chemical speciation in marine/estuarine sediment systems, each with its own characteristic timescale of measurement. An important research achievement of Prof. Chakraborty has been to advance the science of metal speciation by identifying the analytical timescale of measurement as the critical parameter for defining the chemical species in coastal and marine sediment system. Prof. Chakraborty‘s study also helped to understand the influences of Ligand Field Stabilization Energy, water exchange rate, Jahn-Teller distortion of transition metals on their speciation and bioavailability in marine sediments. Prof. Chakraborty‘s work on speciation of metals in coastal and estuarine systems around India pioneered experimental speciation studies in the country in relation to toxicity to biota. He has able to establish the mechanistic linkages between trace/toxic metals speciation, and their bioavailability in coastal marine systems. Prof Chakraborty‘s research has greatly advanced the science of metal speciation in India. Proposer: Dr. Satish Ramnath Shetye, Seconder: Prof. Subhasish Tripathy Ten Best Publications: 1.

DASH, MIHIR KUMAR (b 1973), Associate Professor, Indian Institute of Technology, Kharagpur

Member of the NASI: No (YON 2021, Earth Sciences)

With great pleasure and satisfaction, I nominate Dr. Mihir Kumar Dash for consideration for the elected fellow of NASI. In addition to be an exemplary teacher at IIT Kharagpur, Mihir demonstrated extraordinary commitment to explore, understand and discriminate knowledge on the role of ocean mixing, extra-tropical and polar teleconnection to Indian Summer Monsoon rainfall (ISMR). Using, remote sensing observations and numerical models, for the first time he studied the generation; propagation, dissipation and radiation of energy of internal solitary waves in the seas surrounding Andaman and Nicobar Islands, having scientific and strategic importance. Going extra mile, he discovered a unique process ―Rossby wave breaking in the extra tropics‖ that impacts the ISMR. Additionally, he reviled the presence of wave number – 4 in the southern subtropical SST, and found to impact the summer rainfall over Southeastern Australia. For the first time he predicted an accelerating trend of sea ice extent in the Antarctic, which is well appreciated and referred in the Novel ―State of Fear by Michael Crichton‖. Apart, Mihir is instrumental in producing the first sea ice atlas of the Antarctic, from India. His, research is well appreciated and appeared in the cover page of a reputed journals like IEEE geoscience and remote sensing letters and International journal of remote sensing.

Dr. Prakash Kumar‘s field of research includes both active and passive seismology. His most important contribution is the imaging of the Lithosphere-Asthenosphere Boundary in diverse tectonic regions using international data sets (Kumar et al., 2006, JGR). His findings provide direct seismological evidence for a thin Indian tectonic plate and thus an explanation for its unique fast drift (Kumar et al., 2007, Nature). The detailed mapping of the base of the Indian tectonic plate revealed the post-collisional deformation of the Indian continental plate (Kumar et al., 2013, JGR). Further, his recent findings in the Andaman-Nicobar region provide the first high resolutionseismic evidence for the tearing in the down-going Indian ocean slab (Kumar et al., 2016, GRL). Dr. Kumar developed expertise in utilizing ocean bottom seismological data and provided a Model for Asthenosphere based on the exclusive bore-hole broadband ocean bottom seismological observatory data from Pacific and Philippine Sea Plates and elucidated the nature of pure oceanic plates for the first time that established the variation of Thickness of Oceanic Plate with Age (Kawakatsu, Kumar et al., 2009, Science). He and his colleagues proposed quite a number of new techniques in active and passive seismology. Notable are optimal isolation of P-Sv-Sh components, retrieving the structure without deconvolution (Kumar et al., 2010), shear-wave velocity contrast using P-to-s converted wave amplitudes in anisotropic and dipping layer (Kumar et al., 2014; Kumar, 2015), direct estimation of depth using wide-angle reflection data (Kumar et al., 2003) and Basis Pursuit Receiver function (Sen et al., 2014).

Using Indian MST radar at Tirupati, for the first time he provided observational evidence of downward transport of ozone in tropical region in controlling tropospheric ozone budget and accessed the impact of enhancement in ozone concentration on crop. He has contributed scientifically to several national and international scientific programs (INDOEX,ICARB, CAWSES, APH Hand NCAP). During monsoon, deep convective clouds transport water vapour and momentum up to upper troposphere and lower stratosphere (UTLS). The stratospheric water vapour increases with tropospheric temperature, implying the existence of a stratospheric water vapour feedback. Using satellite data, he provided the evidence of transport pathways of water vapour which actually controls thermal budget during monsoon season over different monsoon regions. Rural sector of India uses solid biomass fuels as energy. He has collected samples of solid biomass fuels used for energy in rural sector across 479 districts of India along with survey and determined emission characteristics of different pollutants from 5000 number of biomass fuels in the laboratory. A brown shroud of pollution engulfs most of the Indo-Gangetic Plains, India and surrounding regions during winter and outflows into the Bay of Bengal fuelled by emissions from indiscriminate biomass burning and fossil fuel combustion. During October and November, source apportionment of pollution over Delhi with the first-time observational evidences of transport of pollution over Punjab and Haryana has proved the role of crop reside burning in the northern India. He has presented a gridded distribution of sources and pollution characteristics over Delhi. Proposer: Dr. S.W.A. Naqvi, Seconder: Prof. Shibaji Raha Ten Best Publications: 1.

Prof. D. M. Maurya has contributed significantly in understanding the development of landscapes in neotectonically active areas of western India. His work in the last two and half decades has fundamentally revised pre-existing notions and knowledge of the Quaternary geomorphic evolution. Meticulous field documentation, precise and extensive field mapping, reconstruction of Quaternary stratigraphy, recognition of neotectonic events in the formation of present landscape and application of Ground Penetrating Radar (GPR), a state of art geophysical technique for investigating the shallow subsurface geology are the major highlights of his research. His significant contributions which have global ramifications are -application of Ground Penetrating Radar (GPR) for investigating shallow subsurface geology. tectono-geomorphic evolution of seismically active fault zones in Kachchh; subsurface nature of large liquefaction (sand blows) formed in 2001 Bhuj earthquake for use as modern analogues for identifying and understanding similar features formed during historic and pre-historic seismic events and establishing phases of Quaternary tectonic activity and its impact on basin evolutionary history of the Gujarat alluvial plain. A large amount of neotectonic database is a prerequisite for unraveling the seismic potential and hazard mitigation in western India that is frequently visited by earthquakes. Dr. Maurya‘s work has filled this gap to a large extent. Proposer :Prof. L.S. Chamyal, Seconder :Dr. R.R. Yadav Ten Best Publications: 1. D. M. MAURYA, Prabhuti Tiwari, M. A. Shaikh, A. K.

Dr Mishra has made outstanding contributions in both fundamental and applied research in the areas of land- atmospheric interactions, surface and groundwater hydrology, and hydrological monitoring and predictions. Dr Mishra‘s research contributed to advancing our understanding of land-atmospheric coupling and its role on hydroclimatic extremes. For instance, Dr Mishra identified the role of intensive irrigation in India on atmospheric aridity, land surface temperature, dry and moist heat extremes, and droughts. In his pioneering research, Dr Mishra identified that intensive irrigation over the Indo-Gangetic Plain causes cooling in land surface temperature but enhances the risk of moist heat stress driven by temperature and high humidity. Dr Mishra led the breakthrough research on the complex interaction of anthropogenic and natural drivers of groundwater storage in India, which has a considerable implication on water sustainability. Dr Mishra quantified the role of groundwater pumping and long-term decline on the summer monsoon season precipitation over India. His research provided a vital understanding of how summer monsoon rainfall characteristics affect groundwater recharge in different parts of the country. Also, Dr Mishra has contributed to developing a real-time monitoring and prediction system for soil moisture, streamflow, and droughts that are essential for managing the depleting water resources in India. The real-time monitoring and prediction system for land surface hydrology was transferred to India Meteorological Department (IMD) for operational use. Dr Mishra has contributed to improving our understanding of the risks of extreme weather events under the observed and future climate in India. Proposer: Prof. P.C. Pandey, Seconder: Prof. A.P.

Dr.Mohan has pioneered polar paleoclimate and micropaleontology multiproxy working group at NCPOR which provided new insights on present and past polar oceanic/climate variation (Mohan et al., 2008; Mahesh et al., 2015; Nair et al., 2015,2019) .Dr. Mohan provided new insights on high latitude biogeochemical cycles, coccolithophore ecology [Mohan et al., 2008], biogeography [Patil et al., 2017], southward expanse [Patil et al., 2020], and adaptation to changing environmental settings [Patil et al., 2019, 2020]. His research on silicifying haptophytes and xenosphres in SO [Patil et al., 2015, 2016] provided clues on their adaptation strategies, structural changes, and elemental composition in changing climate. Dr. Mohan‘s work on lacustrine systems of East Antarctica using multiple proxies provides key information on climate dynamics of last 46ka (Warrier et al 2014;2020;2021; Mahesh et al., 2015, 2017, 2019), relative sea level variation (Mahesh et al., 2018), pedogenesis (Warrier et al., 2020) and sedimentation processes (Warrier et al., 2016). Using fossil diatoms, he has reconstructed latitudinal shifts in past sea ice in the Southern ocean(SO) (Nair at al 2019), contrasting productivity patterns in the frontal zones of SO (Nair et al.2015; Ghadi et al 2020), this latitudinal variation of paleo-Antarctic sea ice and fronts was reflected on Southern Indian Ocean subtropics (influencing the Agulhas leakage passage), which could be a key mechanism linking the Southern Ocean and Asian Monsoon climate systems (Nair et al 2019) and showed evidences of Arctic ocean warming (Harikrishnan et al., 2019).

Dr. NJ Raju‘s noteworthy contributions in the areas of groundwater exploration, assessment and development include construction of subsurface dams (rainwater harvesting structures) to harvest base-flow of ephemeral streams and prevention of salt-water intrusion. These studies lead to agricultural development and productivity in drought-prone areas of Andhra Pradesh. His basin scale water management studies in U.P., Delhi and Odisha are worth mentioning. He meticulously delineated high arsenic contaminated zones in the Ganga flood plains around Varanasi and fluoride contaminated zones in the Sonbhadra region. He precisely delineated the diminishing urban water bodies and devised methods of making them functional. Studies on the effects of weathering in the semi-arid Swarnamukhi River basin allowed him to successfully estimate the CO2 consumption thereby add to our understanding of the global carbon cycle. Dr. Raju was awarded the prestigious Alexander von Humboldt Fellowship in 1997 (Ruprecht-Karls-Universität Heidelberg). Government of India (Ministry of Mines) awarded him the National Geosciences Award 2018. He has edited three major Springer Publications. He organized International Humboldt Kolleg (2013) and a major Geostatistical and Geeospatial Conference (2014) of the International Association for Mathematical Geosciences. He served as a Member of National Groundwater Estimation Committee for revising the Groundwater Estimation Methodology of 1997. He was an Expert Member of the Committee giving PM Awards for Excellence in Public Administration. Results of Dr. Raju‘s meticulous researches are being extensively used by the present-day planners and decision makers in view of their direct impact on the socio-economic development of the farmers and other stakeholders.

PADHY, SIMANCHAL (b 1973), Senior Principal Scientist, CSIR-National Geophysical Research Institute, Hyderabad

Member of the NASI: No (YON 2021, Earth Sciences)

Dr.Padhy‘s research focuses on investigating the nature of small-scale heterogeneities of the earth based on scattering and propagation of high-frequency (>1Hz) seismic waves (Padhy 2005, 2009a, 2009b; Padhy & Subhadra 2010a, 2010b). He uses the state-of-the-art techniques for waveform analysis and numerical modeling of wave propagation in complex media (Padhy et al. 2014). He analyzed earthquakes over different parts of India and Japan for characterizing the attenuation properties of the medium including the highly heterogeneous subducting slabs (Padhy et al. 2011a, 2011b; Padhy & Subhadra 2013). His major findings, especially on theoretical seismology, explain the origins of complexities of observed seismograms, while advancing our basic understanding of theory of wave propagation (Padhy et al. 2007; Padhy 2009a, 2009b; Padhy et al. 2014). He found seismic attenuation from observations and experiments can be reconciled in the framework of self-similar scaling from field to lab scale. He along with his students analyzed ambient noise to image the lithosphere beneath Madagascar Island to a resolution higher than that expected from conventional earthquake tomography (Adimah & Padhy 2020a, 2020b). Dr. Padhy contributed to the field of earthquake engineering by modeling earthquake strong ground motions for parts of India with scarcity of data (Subhadra et al. 2015, 2018). These findings have large impact on seismic hazard assessment of India. Recently, he extended the concept of fractal scaling in Seismology (roughness of slip) to Biology to investigate scaling of surface roughness of the SARS-nCoV (Padhy & Dimri 2020), which highlights his potential in inter-disciplinary science.

It is a pleasure for me to nominate Professor R. S.Rana for the fellowship of the Allahabad Academy. He completed his Ph.D under my guidance in the 1985 from Panjab University, Chandigarh, on the Intertrappean beds of the Nagpur region. His work revolutionized thinking on the age of the Deccan Volcanics as he was able to show the presence of dinosaurs suggesting that at least part of the traps were Cretaceous in age. In a collaborative team work, it was shown that the Deccan Volcanics were of relatively short duration based on Ar-Ar dating and palaeomagnetic stratigraphy ( Besse et al. 1986) is landmark contributions in the Cretaceous include the discovery of primitive mammals that lived in the shadow of the dinosaurs. His work on the microvertebrates of the Fatehgarh Formation opened the way for further investigations in this oil-bearing reservoir. The outstanding research is what he undertook in a team effort on understanding the biotic dynamics of the drifting Indian Plate. He was the first to demonstrate the presence of mammals in the Lower Eocene Lignite mammals as far back as 2004. In the last 16 years, our understanding of modern Indian fauna and flora, evolutionary lineages of odd and even-toed ungulates, the oldest birds, and diverse organisms such as lizards, snakes and frogs, is largely as result of his initial discoveries. His research has a cumulative impact factor of XXXX with papers in the highest ranked journals such as Proc. Royal Society, London, PNAS and Nature Communications, etc Proposer : Prof. Ashok Sahni, Seconder : Prof. G.V.R. Prasad Ten Best Publications :

Prof Sangode after joining Wadia Institute of Himalayan Geology (WIHG) in early 90‘s, established Rock Magnetic and Palaeomagnetic laboratory. His extensive work on the Siwalik Magnetostratigraphy provided chronologic framework to >10Ma mammalian fossils bearing sequence of India. Rock magnetic approach developed by him during 90‘s was also a first-time tool to reconstruct paleoclimate and paleomonsoon signatures from the Siwalik paleosols. He further introduced magnetic fabric approach to understand fluvial processes amongst paleochannels. The DST-BOYSCOST fellowship award in 1999 was landmark in his career. His publications since then reflect pioneering applications, development of systematics, new approaches and collaborations in demanding areas of research. The recognition of his work was witnessed when the NATIONAL MINERAL AWARD was bestowed upon him in 2006. Sangode joined Pune University in 2006, developed another magnetic lab there and continued collaborations with university departments and colleges in many novel areas including paleoclimate, geoarchaeology, sediment source unmixing, anthropogenic loading etc. He carried extensive field work in Quaternary archives of Himalaya, Bengal fan, Godavari basin, coastal sediments and laterites by developing teams of young workers. A living example of his long-standing association is with Deccan College Post Graduate Research Institute on aspects like chronology, paleoenvironments and pottery firing temperatures. His ongoing work on Paleocene/Eocene is rightly demanding to provide magnetostratigraphic framework on the globally significant thermal maxima (PETM global warming). His futuristic focus on many frontline research themes deserves nomination to the esteemed National Academy of Sciences, India. Proposer: Prof. S.N. Rajaguru, Seconder: Prof. B. R.

Dr. Singh has significantly contributed to the advancement of airborne and spaceborne PolSAR remote sensing by introducing new Generalized 4-component Scattering Power Decomposition (G4U) [IEEE TGRS, 2013], 6-component Scattering power Decomposition (6SD [IEEE TGRS, 2018] and 7-component Scattering power Decomposition (7SD) [IEEE TGRS, 2019] methods in the inversion techniques for retrieving cryo-/bio-physical parameters for monitoring the environmental state of Earth [RSE, 2019, 2020]. These decomposition methods offer promising straightforward interpretation of the real world [IEEE TGRS, 2020]. His research contributions also attempt to bridge the intellectual gap between traditional radar polarimetry theories/methods and monitoring the Earth surface parameters. He has developed novel polarimetric radar remote sensing inversion algorithms and methodologies for retrieving snowpack parameters (snow wetness, density, depth, and snow water equivalent) in the Himalayas [IEEE TGRS, 2017, 2021; RSL, 2020]. He discovered anomalous glacier dynamics and disintegrating behaviour of glaciers [RSE, 2020]. A new climate warming feedback mechanism due to meltwater influx of retreating tributary glaciers is introduced [RSASE, 2021]. These contributions fill significant gaps in knowledge about glacier dynamics and heterogeneous ice loss. The impact of glacio-hydrological warming feedback mechanism on glacier slip/deformation, dead ice formation and collapse events in the Himalayas is also revealed [RSE, 2020]. Inclusion of feedback mechanism will reduce the uncertainty in the results of existing models and improve future projections of ice loss and understanding of massive glacier collapse events in the past {for example, in Aru glacier, Tibet, 2016, and in Rishi Ganga catchment, 2021} leading to improvements in future predictions.

Paleosol-based research in India is in its nascent stage despite its enormous potential in paleoenvironmental reconstructions that are comparable to the marine proxy records. The field is poorly represented in the country, but Prof. Pankaj Srivastava has taken up to develop the field of paleopedology in the country. He is well-known for his work on mineral weathering and pedogenic/palaeopedogenic processes. He has developed an excellent paleopedology lab setup, which is the only of its kind in India where micromorphology, clay mineralogy, and geochemistry of the soils and paleosols are explored in-depth to unravel the geological history of the terrestrial sediments. His students are well-placed in various institutions carrying forward the work. He innovatively used soils and paleosols to integrate the geological, geomorphological, pedological principles to understand the Earth System Evolution in a better way. Salient features of his research include: Establishing five soil- geomorphic surfaces in the monotonous Gangetic Plains, Clay mineralogical record of ~100ka of the Ganga Basin, Loess-paleosol sequences related to advance/retreat of glaciers in the Himalaya, Nonmarine sequence stratigraphic framework of the Ganga Basin, Evidence for an early Oligocene monsoonal system, and Latitudinal control in the formation of the red and the yellow paleosols in the Himalaya. His research has been published in high-impact journals like Sedimentology, JSR, and ESR, etc. The research is extensively utilized by researchers (Scopus 1034, H-index 20) and also in 61 books/encyclopedias like Geology of Fluvial Deposits by Miall, Active Tectonics by Schum, and Encyclopedia of Geomorphology.

Suresh Babu has made outstanding and original contributions to the science of the microphysics of atmospheric aerosols and its consequence on regional climate impacts through carefully made multi-platform (network of observatories, shipboard and airborne as well as balloon borne) measurements and synergizing them with regional climate models. His works leading to the quantification of regional radiative impacts of elevated Black Carbon (BC) aerosols layers in the free troposphere through atmospheric and cryosphere feedbacks as well as through aerosol – cloud interactions are seminal in nature. He discovered (using ingenious experiments with high altitude balloons and aircrafts) layers of enhanced BC concentration in the free troposphere, the radiative forcing due to which increased the atmospheric stability, leading to a positive feedback on the layer life time and further enhancement in forcing. Using multi-decadal aerosol optical depth data from the network of aerosol observatories (ARFINET) he has quantified the long-term trends in aerosol optical depths over India, its causes and climate-impacts. He has published 164 papers with a total citation of 6538 and h-index 43. The merit of his work has been recognized by several awards/honours at different phases of his career, which include the INSA Young Scientist Medal (2006), Young Associate of the Indian Academy of Sciences (2007), NASI Platinum Jubilee Young Scientist Award (2009), NASI SCOPUS Young Scientist Award (2009), Swarnajayanti Fellowship from DST (2014), Shanti Swarup Bhatnagar prize (2017), MoES National Award of Excellence in Atmospheric Science (2020) and Fellow of the Indian Academy of Sciences (2021).

Dr. Vedanti made noteworthy contributions by carrying out dynamic reservoir characterization using innovative geophysical techniques to monitor the reservoir-recovery processes and optimized the strategy for implementation of EOR Process in Balol and Ankleshwar oil-fields. ‗Balol‘ is one of the very few fields where in-situ combustion is successfully implemented, making this study very important (Geophysics-2009, JGE-2010, Interpretation-2015, JAES, 2018, BookChapter-2015, J.Appl. GPH-2016, JGSI-2016, NPG-2014, Ganguli 2016, Ph.D.). ‗Geophysics‘ and ‗JGE‘ papers were most-downloaded articles of the respective journals. Subsequently, she co-authored a book ―Fractal Models in Exploration Geophysics: Application to Hydrocarbon Reservoirs‖ Elsevier(2012). This work was appreciated through the National Geoscience Award(2012). Dr. Vedanti is the first researcher to report high intrinsic seismic attenuation, anomalous Qs/Qp, and low-velocities in some of the massive Deccan-Basalt cores (PAGEOPH-2018). These findings brought paradigm-shift in the modeling of the Deccan Traps (Malkoti 2019, Ph.D.). Further, to quantify the intrinsic attenuation in a dynamic media, she produced evidence of slow-P waves not seen at predominant seismic frequencies in the CO2-flooded reservoir (Acta Geophysica-2020, Geophysics Revised) and developed a scheme to model it (Geophysics Revised). Dr. Vedanti‘s early-career research was commendable; she modified the convergence of well-known Occam‘s Inversion and developed an efficient inversion scheme (Comp&Geosc-2005). Recognizing her significant contributions Society of Exploration Geophysicists(SEG), USA selected her as the SEG Honorary Lecturer for South and East Asia (Jan-June 2021). As visible from the list provided on the SEG website, she is the youngest such awardee from India and has made the entire Indian Earth Science community proud.

Dr. Sarma's contributions significantly advanced our understanding of the spatio•temporal variability of biogeochemical processes in Indian estuaries. His work identified that reduced river discharge triggers phytoplankton blooms and oxygen minimum zone (OMZ) (Acharyya et ai., 2012). His group estimated for the first time the emission of trace gases from the Indian estuaries and showed it is much less than anticipated by international community (Sarma et ai., GRL,2012). A novel feature of results has implications to ecosystem functioning and extent of human interference, biological productivity and biogenic fluxes (Sarma et ai., Tellus, 2015; MPB, 2018). Through isotopic studies, he has demonstrated that chemicals from agricultural waste are mostly retained in ground water (Kumar et ai., ESPR, 2020); a finding that negates international allegation on India polluting the oceans through excess fertilizers. His extensive investigations in the Bay of Bengal (BoB) helped to understand biogeochemical fluxes including biogenic gases of climate significance (Sarma et aI., Tellus B, 2012). He has shown that the OMZ in BoB is unlikely to turn anoxic since anticyclonic eddies keep pumping atmospheric oxygen periodically into the Bay (Sarma et aI., CSR, 2018). First ever results from vitro-experiments reveal that atmospheric aerosols deposition not only promotes productivity and alters diversity of plankton but also contribute to ecosystem acidification (Sarma et ai., Tellus B, 2015; Yadav et ai., Mar Chern, 2016). Most significantly his estimates of trace gases fluxes to the atmosphere from estuaries and Indian Ocean (Sarma et ai., GRL, 2012) are well recognized in IPCC Assessment Reports. Proposer : Dr. M.

Dr. Balaram made original contributions in the exploration of gold and PGE in different parts of Peninsular India, Indian Ocean and some parts of Precambrian terrains of Madagascar (Balaram et al, 1997; Balaram et al. 2006; Balaram et al. 2013; Balaram et al. 2019). His collaborative studies with NIO & NCAOR, Goa, led to the identification of significant enrichment of REE and PGE in ferromanganese crust samples from the Afanasy–Nikitin Seamount in the Central Indian Ocean (e.g., Balaram et al. 2006; Balaram, 2012). He initiated studies on the environmental effects of autocatalytic converters in transport vehicles for the first time in India, in cities such as Bangalore, Hyderabad and Visakhapatnam, and found significant increase in Pt, Pd & Rh and other harmful trace elemental concentration levels in certain high traffic areas of these cities (e.g., Balaram, 2020). He published ~300 SCI papers in reputed journals which are being cited extensively in the scientific literature (~ 4400 citations with 35 H-Index and 102 i10 Index up to March, 2021 and guided 5 PhD students.

Dr. Chakraborty joined the Physical Research Laboratory in 1987 as a Ph.D. student. He applied the isotopic techniques in paleoclimatic reconstruction (Ref: 7). He initiated the study of isotopic study of corals from the Indian coasts and demonstrated their potential in the paleo-climatic investigation (2,3). Using deep-sea corals from the Drake passage, he estimated that the ocean overturning circulation was much weaker around 16-17k yr ago Ref: 1). He also studied the past climatic processes using numerical models (4,9). Currently, Dr. Chakraborty is actively involved in the study of monsoon processes using isotopic tracers (5). For the first time, he demonstrated that the bio-meteorological parameters such as plant transpiration could be used to delineate the active and break phases of monsoon (8). Dr. Chakraborty also works on the atmosphere-biosphere exchange of energy and carbon fluxes using the eddy- covariance technique. He started the Metflux India project under which micro-meteorological towers were established in a few natural eco-systems in India. His work for the first time showed that the maximum carbon uptake in the forest of NE India takes place during the pre-monsoon season (6). Afterward, the carbon sequestration potential of these forests weakens, and in the winter, they act as a source of carbon. This is in sharp contrast to the rest of India, where maximum carbon uptake takes place during monsoon to early winter (10). Proposer: Prof. Karumuri Ashok, Seconder: Prof. K.S.

Dr. Ramesh developed cutting-edge techniques based on information theory, inverse modeling and Bayesian statistics towards understanding the complex lithosphere-atmosphere-ionosphere-magnetosphere (LAIM) system. His ‗break through‘ initiative of ‗Ionosphere-Seismology‘ enabled identification of an ionospheric precursor for a Tsunami. He deciphered the elusive earth-ocean-atmosphere processes by exploiting the power of ‗Entropy‘ as applied to time series data. He is ‗the first‘ to use the delay-time tomography to obtain 3-D images of the structure and velocity dissimilarities within Deccan volcanic province and ascribe it to the anomalous low velocity zone. He convincingly showed ‗seismic anisotropy‘ in the South Indian shield and also developed P-velocity models using reflective synthetic-seismograms. He demonstrated that the crustal thickness and composition primarily depend on ‗mode formation‘ than ‗age‘. Through orientation studies of the Eastern Ghats and Dharwar regions he rewrote the robustness of the Indian plate and also identified prospective regions for diamonds. He explained the additional mantle features as due to plume - normal lithosphere interaction and used the differential times as a geothermometer to show the ‗pacific plumes‘ originating in the lower mantle. He effectively used ‗entropy metrics‘ to understand the structure of the earth‘s crust and underlying mantle in diverse geological provinces. While providing insights into several aspects of the earth‘s interior with unprecedented finesse, his new results on the global warming due to the ‗green-house gas emissions‘ vis a vis the negative impact of the ‗volcano emissions‘, drew global attention. His diverse research interests extend even to ‗predicting‘ the solar cycle characteristics and magnetospheric conditions. Proposer: Prof. Abhijit Sen, Seconder: Prof. R.

Subimal Ghosh‘s significant research contribution lies in estimating the high moisture contributions from land to the Indian monsoon rainfall during latter half of season. With this better understanding, Subimal was able to improve the monsoon simulation using land-atmosphere model. This work was selected as the Research Spotlight of American Geophysical Union. Recently he has developed a module for inclusion of paddy irrigation and Indian irrigation practices in the Community Land Model and experiments with this module have showed significant feedback from human water management practices to monsoon processes. With the improved understanding of monsoon circulation processes, Subimal has developed physics guided data driven statistical-dynamical model for monsoon characteristics. The statistical algorithms developed by him on regional projections of Indian monsoon with the multi- model uncertainty assessment have significant implications for water resources planning in India. Subimal has also worked on converting hydrometeorological discoveries into society relevant products. He led a consortium of 30 scientists from 8 institutions to develop India‘s first real-time integrated urban flood forecasting system for Chennai and this is now operational. His recently patented tool on farm- scale irrigation water management, when demonstrated to farmers in India, suggested the possibility of 20% to 30% of water saving compared to current best practices. His other pending patent relates to extended range flood-risk forecasts based on weather and hydrologic predictions, geomorphological & socio-economic vulnerability to floods. Subimal is the recipient of AGU medal, Shanti Swarup Bhatnagar Prize, Swarnajayanti Fellowship, Young Scientist and Engineer awards from INSA, NASI and INAE.

Dr Kumar‘s total professional career profile, spanning over 35 years, has one common thread - to ensure engineering geological inputs of the highest level to the various highway engineering projects, especially those under the sustained shadow of landslide hazards. The widespread practice of trying to fix landslides without proper geoscientific investigations in 1980‘s has given rise to cases of failure instead of success in treating the landslides. I have the satisfaction in writing that he has not only provided timely engineering geological interventions to highway engineering projects but also pro-actively demonstrated by live examples the difference landslide investigation and research can make on the landslide correction - practice, particularly in Himalayan regions. One of his early significant contributions has been to demonstrate through his projects the consequences of landslide hazard, vulnerability and risk mapping by neglect of geoscientific mapping and investigation. After nearly a decade of sustained effort, in 2002, a GIS-based landslide hazard susceptibility map was delivered to DST. Closely related to this was the delivery of a first subsurface Geotechnical Database of Delhi for the first cut Seismic Microzonation of Delhi. His contribution in the area of early warning against landslides and to the design of cost effective and environmentally friendly landslide remediation packages is significant. The first ―Engineering guidelines for landslide mitigation‖ developed in 2015, for Indian Road Congress, greatly enhances the understanding of the problems of landslides in right perspective by the working engineers followed by the design of an appropriate strategy for their management, which was long overdue.

Prof. Manju Mohan has made pioneering contributions to the field of Atmospheric Sciences on problems of social relevance as well as scientific importance as per national needs, in her research career of about four decades. Prof. Mohan has conducted extensive studies on urban heat island (UHI) related to field campaigns, satellite-derived measurements, numerical modelling with urban canopy effects, exploring land use/land cover dynamics, thermal comfort and UHI mitigation measures with sustainable materials such as bamboo. She has introduced a new concept of using an intra-city reference site for UHI estimates, instead of a rural site which is impractical to use now. Her work has quantified how urbanisation over 50 years impacted in various ways the local meteorology, UHI, thermal stress and air quality. Her work on industrial heat islands, is amongst the early attempts internationally. Fog prediction studies undertaken by Prof. Mohan are some of the early efforts in India. Her work involved the development of an empirical approach using a numerical model that achieved 94% success rate of prediction of foggy as well as non-foggy events. Prof. Mohan has contributed extensively in Boundary Layer Meteorology, mesoscale numerical modelling of atmospheric phenomena, air quality modelling and provided new insights with focus on Indian climatic conditions. Prof. Manju Mohan is also a constant part of the academic community of stakeholders, and member on distinguished expert committees. Her studies are covered widely by the national dailies, important magazines, television channels, AIR, and in August 2019 in Tedex, AIIMS.

Prof N.V.Chalapathi Rao has made original and path breaking fundamental contributions on the petrogenetic and petrophysical aspects of kimberlites, lamproites, lamprophyres, their entrained xenoliths and mafic dykes which enriched our understanding of the mantle processes through geological time. He has established an important school of deeper mantle petrology in India and his innovative researches demonstrated as to how small-volume melt products such as kimberlites, lamproites and lamprophyres and their xenoliths can shed significant insights into large-scale geodynamic and metallogenic aspects such as (i) link between kimberlites, flood basalts and mantle plumes, (ii) non- terrestrial source for the anomalous Ir enrichment at K-Pg boundary, (iii) origin and original spatial extent of the Proterozoic sedimentary basins and the Deccan Traps, (iv) Mesoproterozoic mantle heterogeneities and chemical geodynamics in Dharwar craton, (v) supercontinental (e.g., Rodinia, Columbia) reconstructions, (vi) nature and thickness of pre- and post-Deccan lithospheric mantle in NW India and (vi) diamond prospectivity. As a PI (SERB), he has set up a state-of-the art EPMA and SEM labs at BHU in 2016 and 2018 respectively and they emerged as leading analytical facilities of the country pursuing world-class petrological research helping scores of researchers and students.

Prof. Janardhan has provided pioneering results on Sun-Climate relationship and on Planetary Atmospheres. His studies on the nature and behavior of solar activity and its likely impact enables anticipation of future global climate. In each solar cycle of 11 years, the sun‘s activity, measured through sunspot number, rises and peaks, its magnetic field reverses, and the activity declines. His analysis of the solar wind and solar magnetic fields during the last four solar cycles, showed a steady and continuing decline in magnetic fields, since the mid-1990s. These have resulted in a lower solar wind dynamic pressure and an outward expansion of the earth‘s magnetosphere by one earth radius, and enabled him to predict that a Maunder like Solar minimum is on the anvil wherein, sun-spots will be absent for many decades thereby impacting rainfall events, radio communication, and other non-anthropogenic climate effects associated with global cooling and weather patterns. Using measurements of solar magnetic flux transport, he has developed a new method to predict the amplitude of the next solar cycle. Recent Chandrayaan-2 observations provide support for the above through low levels of solar X-ray emission. Using observations of quiet sun micro-flares he addressed the long-standing problem of the million degree corona and confirmed the hypothesis that micro-flares, contribute significantly to coronal heating. His work on planetary atmospheres and astrochemical ices has led to the discovery of ozone on Callisto and showed how that cold interstellar dust can contain crystalline, geometric shapes, which in turn would impact its polarization properties.

The nominee has made fundamental contributions to the taxonomy, diversity and evolution of murine rodents and their usefulness in establishing a regional biochronological framework and interpreting past monsoonal conditions (Patnaik, 1997; 2001; 2003; 2013; 2018; Kimura et al., 2013). By integrating aspects of stable isotopes, microwear and enamel microstructure, his work has improved our understanding of age and ecology of extinct hominoids (Patnaik et al., 2005; Pillans et al., 2005; Sehgal and Patnaik, 2012; Gilbert et al., 2014; Singh et al., 2018). He provided new evidence of connections of Siwalik mammals with other parts of the world (Patnaik, 2016). He described two new mammal genera, one of a lagomorph and one of a primate and several new mammalian species (Patnaik, 2002; Gilbert et al., 2017). He was involved in the cladistic analyses of the Narmada cranium, the only hominin found from India till date, showing closer relationship with the European Steinheim specimen (Cameron et al., 2004). Using various dating methods, he found that the famous hominin fossil from Narmada was reworked. In the Kurnool Cave deposits he and his colleague found that the disappearance of several vertebrate taxa was probably due to a very arid phase of the Last Glacial Maxima (LGM) (Patnaik et al., 2009; Morthekai et al., 2015). He and his colleagues discovered new hominoids/primates, ostrich-like eggshells, new pelican and darter fossils from the Siwaliks; Late Cretaceous rice from central India; and Miocene and Pleistocene mammals from the Baripada, Odisha (Patnaik et al., 2009; Prasad et al., 2011).

The research career of Dr. Francis P. A. is focused on the numerical ocean modeling and the interannual variability of Indian summer monsoon. Using the simulations by very high-resolution ocean models configured by him and the observations of coastal currents, Dr. Francis and his students described the three dimensional structure and variability of the tidal and sub-tidal circulation in the Bay of Bengal. The deep insight of Dr. Francis on ocean modeling and ocean processes enabled him to take leadership in developing the High resolution Operational Ocean Forecast and reanalysis System (HOOFS)- the operational ocean forecast system of India. HOOFS comprises a suit of numerical ocean models configured by Dr. Francis, to which near-real time ocean observations are assimilated. Dr. Francis has also made very significant contributions to the challenging problem of understanding and predicting the year-to-year variability of the Indian summer monsoon rainfall (ISMR). As a part of the doctoral research of Dr. Francis discovered the Equatorial Indian Ocean Oscillation (EQUINOO)- a see-saw in clouding over the western and eastern parts of the equatorial Indian Ocean. In a series of subsequent publications, he and his collaborators have shown that, in addition to the El Nino and Southern Oscillation (ENSO), EQUINOO also contributes independently to the interannual variation of ISMR and the two modes together determine the extremes of ISMR. This deeper insight helped Dr. Francis and his collaborators to make an ‗educated guess‘ about the evolution of EQUINOO in 2019, which was later proved to be correct.

Mathematical models are used for making selection of an appropriate scheme of aquifer recharge and pumping to achieve objectives of sustainable development and management of groundwater resources. Earlier models were developed based on assumption of constant recharge rate which is otherwise varying with time. Dr. S.N. Rai for the first time has developed many groundwater flow models based on time varying recharge rate for single recharge operation since 1979 onwards. Later on Drs. Rai and Ajay Manglik (F.N.A.Sc.) invented a method to simulate any complex nature of variation in recharge rate from any number of recharge basins of different size and for any number of recharge cycles. Same method can be used to simulate time varying pumping rates from any number of wells as well as leakage rate. He obtained US patent for this newly invented method and has developed several predictive models based on it. He carried out Electrical Resistivity Tomography in parts of drought prone Vidarbha and Marathwada regions for delineation and sustainable development of groundwater resources. Dr. Rai for the first time has demonstrated sustenance of bore well yield by casing entire depth and use of perforated pipes within the water bearing aquifers which was not practised earlier. He also modeled crustal thermal structures of central India across Narmada Son lineament, Cambay basin and Godavari graben to decipher distributions of surface heat flow and subsurface temperature, depth of Curie isotherm, Moho temperature and boundaries between brittle-ductile zones. Such knowledge helps in understanding seismotectonics, maturation of hydrocarbon etc. Proposer: Dr. Ajai Manglik, Seconder: Dr. V.M. Tiwari Ten Best Publications: 1.

Dr. Krishna Kant Kumar Singh is well known Geophysicist having specialization in shallow-surface activities. His researches have enhanced both mining safety and production. He is actively working for the development of modern and sophisticated geophysical techniques and their applications in the field of mining and environment. He has developed a new Ground Penetrating Radar system namely ―MineVue‖, world‘s first intrinsically-safe longest range and lowest frequency shielded radar system, having depth of penetration 60 m for delineation of barrier thickness in underground coal mines to mitigate inundation hazard. This system has been granted permission by Directorate General of Mines Safety for use in underground gaseous coal mines and helped enable coal mining industry to exploit the coal with enhanced safety which were unapproachable and abandoned. He has delineated barrier thickness in different underground coalmines and addressed the long pending major safety issue of the mining industry (Singh, 2014 &2015; Singh and Jan Francke, 2014). Dr. Singh has identified unapproachable mine galleries below railway lines and national highways to protect the human beings and national property (Singh, 2015; Singh et al, 2018, Kushawaha et al, 2019). Dr. Singh‘s innovative applications of Resistivity Imaging and GPR surveys not only increased the safety of the inhabitants and important ground structures but also enabled extraction the coal below the ground structures (Singh et al. 2016; Singh, 2006, 2008, 2013, 2014, 2015; Soni et al, 2007; Singh et al., 2004; Singh and Chauhan, 2002).

Professor Daya Sagar's most innovative contributions are on mathematical morphology-based spatial algorithms to process and analyze mathematically the surficial phenomena and processes through remotely-sensed satellite data. These spatial algorithms—for spatial and spatiotemporal data covering the broad but interrelated areas of geo-pattern retrieval, geo-pattern analysis, geospatial reasoning, and simulation and modeling of geospatial phenomena and processes—are summarised in his monograph Mathematical Morphology in Geomorphology and GISci, CRC Press, p.542, 2013. Most salient discoveries and observations are that he has (i) shown the evidence of self-organization in several terrestrial phenomena and processes via scaling laws, (ii) provided approaches to derive scale-invariant but shape-dependent indices for better terrestrial analysis, (iii) shown through discrete simulations based on the interplay between numeric and graphic analyses various behavioral phases that geomorphologic systems traverse. These path- breaking contributions–evidenced through ninety journal publications, eleven monographs, and/or edited theme issues–and the ways in which his expertise has been applied to a range of questions of importance to mathematical geosciences, remote sensing, and geographical information science have won Prof. Sagar, a world-renowned mathematical geoscientist, top awards and honors including the ―Dr. S.

Nominee's work includes not only fundamental contributions in the field of tropical atmospheric chemistry, focusing on air pollutants and short-lived climate forcing parameters, but also system development and impact assessment for practical applications to the society. His work includes formulating new chemical schemes and empirical parameterisation to augment and indigenise current coupled atmospheric chemistry transport models. This has significantly enhanced the skill of short to extended range air quality forecast. Nominee developed high-resolution gridded emission inventories of major chemical species for different metro cities and coarser at India level that not only fulfilled the critical input for chemical models but also helped plan mitigation strategies. He explained processes leading to extreme pollution events owing to stubble burning, dust storm and severe weather and quantified relative share. Nominee evolved India‘s first metro air quality forecasting system in four Indian mega cities and after demonstrating the skill, it is implemented as an operational service. He has pioneering work in the middle atmosphere in identification of greenhouse signal. He worked both on experimental data as well as upper atmospheric general Circulation model. This work exploited the upper atmospheric temperature trends revealing cooling in this region as against warning near surface, as a result of increase in greenhouse gases. This finding has strong implications in navigation system, radio communication, and satellite movement. Proposer: Prof. Prem Chand Pandey, Seconder: Prof. S.N. Tripathi Ten Best Publications: 1.

PERUMAL, R. JAYANGONDA (b 1971), Scientist E Wadia Institute of Himalayan Geology, Dehradun

Dr R.Jayangonda Perumal motivated by the goal of understanding the relationship between strain accumulation (i.e. Geodesy) and strain release (Earthquake Geology) in the context of the mechanics of the earthquake and mountain building process and to quantify the seismic hazard associated with the globes largest continental thrust system, the nominee has implemented paleo-earthquake studies at 27 sites along Indian Himalayan Frontal Thrust since 2002. Dr Perumal‘s used a fallout radiocesium isotope Cs 134 as a chronomarker for the first time in the Science of Paleoseismology to demonstrate the 1950 Assam earthquake produced primary surface faulting along the Himalayan Frontal Thrust (HFT), at Pasighat, NE Himalaya. Presence of radiocesium beneath the fault zone in northeastern state provides the first transcontinental transport of radioactivity from the Hiroshima-Nagasaki twin atomic bombing (August- 6 and 9, 1945) to Indian subcontinent. His study settled the debates on fault mechanisms of the 1950 event and suggests that Himalayan great earthquakes are not blind (Scientific Report-2017). He discovered the surface rupture of 1697 Sadiya earthquake and estimated its magnitude (Scientific Report-2021). Dr Perumal mapped several active faults in the Kumaun-Garhwal regions through field with an aid of satellite imageries (Book-Springer). This book is not a review rather it discusses the data on active fault elements collected by a team lead by the nominee. Simultaneously, he has developed for the first time an Interactive Web-Based Himalayan Active Fault Database Interface System (WHADIS), available at Wadia Institute Server (http://www.wihg.res.in/whadis-himalaya) for open access that will inform engineers and policy makers about earthquake hazards.

Prof. A. D. Singh has made outstanding contributions to the understanding of Indian/south Asian seasonal monsoon variability on tectonic, orbital to sub-orbital and centennial scales. He provided for the first ever a clear documentation of Indian winter monsoon variability and its role in Arabian Sea productivity pattern on millennial scale, and discovered a breakdown of winter monsoon intensity and productivity during the cold phases of the northern Hemisphere. His new findings opened up new vistas for paleomonsoon research and climate modelling. Prof. Singh has carried out pioneering work on the Arabian Sea pteropods and developed several new pteropod proxies, which brought out revolutionary changes in Quaternary paleoceanography, particularly to our understanding of deep water circulation and its effects on biogeochemical cycling. Through his integrated approach, Prof. Singh uniquely illustrated history of past changes in the entire water-column (upwelling, productivity, sea surface temperature, sea surface salinity, water column oxygenation, ventilation) in the eastern Arabian Sea on high resolution scale and their linkages to seasonal monsoon strength and global climatic perturbations. These studies will have far reaching effect on understanding the dynamics of the monsoon, its prediction and impact on ocean environment and marine life. Research findings of Prof. Singh from NE Atlantic Ocean provide better insights into our understanding of linkages between global ocean circulation and climate change. Having been involved in various IODP programs and activities, Prof. Singh has contributed significantly to the growth of paleoceanographic and paleoclimate studies in the country.

Dr. Anil has made significant contribution to our understanding of food-web dynamics and inter- and intra-trophic-level processes in the ocean. His research addresses the question: what triggers the ecology of monsoonal ecosystems and how does the ecosystem respond to perturbations? His early work describes the causative processes that regulate phytoplankton community dynamics in the seas around India. He innovatively coupled field observations and experiments to elucidate the impact of monsoonal and anthropogenic pressure on the marine ecosystem and pelago- benthic transitions in marine invertebrates. A key application of his research is in the field of marine bioinvasion. He has enabled establishment of baseline information critical in bioinvasion research: notable contributions include dinoflagellate cyst distribution, important from the perspective of Harmful Algal Blooms, along the Indian coast. Identifying the importance of regional co-operation to address marine bioinvasion, he took up the initiative to forge collaborations with South Asian and ASEAN countries and is engaged in the realisation of a regional action plan. During the 12th Plan, Dr. Anil led an inter-disciplinary team to study the sea-surface temperature fronts that are used to map potential fishery zones. The physical and ecosystem variables were mapped at a hitherto unprecedented spatial resolution. The observations show that phytoplankton groups respond strongly to perturbations within these fronts, with the age of the front and the background conditions playing a major role in determining the ecosystem response. An outcome of this project is a proposal for a trans-disciplinary, national, mission-mode programme that seeks to couple oceanography and fisheries. Proposer: Dr. Satish R.

MUKHERJEE, ABHIJIT (b 1976), Associate Professor, Department of Geology and Geophysics, Indian Institute of Technology Kharagpur, Kharagpur

Member of the NASI: No (YON 2018, Earth Sciences)

Dr. Abhijit Mukherjee, the nominee, is regarded as one of the foremost groundwater geologist of India, and one of the first recipient of Shanti Swarup Bhatnagar Prize in the subject. Abhijit‘s research on quality and quantity of groundwater-sourced drinking water has significantly contributed to the advancement of Indian groundwater research. His research showed that arsenic contamination occurs at depths >100 m in aquifers of the Ganges-Brahmaputra basin, because of hydrostratigraphy and intensive irrigation groundwater pumping. He has since extended his studies to the Bengal basin in Bangladesh; Indus valleys in India; the Huhhut basin of China; Kentucky and Texas, USA; and the Andean basin in Argentina, Bolivia and Chile. Recently, he applied AI in predicting the groundwater conditions across India. He has developed a global conceptual model that integrates tectonics and surface processes to explain worldwide arsenic cycling and mobilization under different hydrogeochemical conditions. Mukherjee‘s recent research work have also significantly contributed to support and evaluate the Government of India (GoI) missions like MNREGA on groundwater rejuvenation in India, groundwater pollution for Swatch Bharat Abhiyaan, understanding the drying and pollution of river Ganga for Namami Gange mission, etc. Abhijit deserves the Fellowship based on the publication of results of research. He is remarkably productive, having authored or co-authored 100+ international journal articles in geology, hydrology, and environmental science. He has also edited four books and authored 36 chapters in books and proceedings volumes. The number of citations his work has garnered (>3400) speaks to its significance. Proposer: Prof. P.C.

PATRA, AMIT KUMAR (b 1966), Director, National Atmospheric Research Laboratory (NARL), Gadanki

Member of the NASI: No (YON 2018, Earth Sciences)

Dr. Amit Kumar Patra is an innovative scientist and undisputed expert in radar probing of the atmosphere and ionosphere. His pioneering work has been primarily on mesosphere and ionospheric plasma irregularities/instabilities and constitutes the most comprehensive view of off-equatorial low-latitude plasma irregularities and the coupling processes. He has discovered two distinct types of 150-km echoes and proposed an interchange instability process involving metallic ion layer and the complex role of photoelectrons. He has experimentally demonstrated seed plasma structures deciding the growth of the Rayleigh-Taylor-Instability, generating plasma bubble and irregularities- components of Space-Weather with adverse impact on satellite-based communication/navigation applications, and coupled with theoretical simulation proposed a prediction strategy. He has established the Gadanki Ionospheric Radar Interferometer (GIRI) among other instruments alongside the Advanced Indian MST Radar (AIR), which he used to uncover plasma processes including the frequency dependent response. His recent works on Moon imaging and Space Debris using AIR have attracted national attention. During the last three years of his directorship, he has upgraded NARL by establishing an X-band DWR, 1.7 Petaflop HPC, Hyderabad Observatory and Kolkata Observatory, and started a Cooperative-Research-Platform using the five existing ST/MST radars to strengthen atmospheric research in our country. His current research and laboratory upgrade include meteorite/meteor research with GIRI and AIR, long-baseline interferometry/imaging, incoherent scatter applications of AIR, and realization of a Space-Borne cloud-precipitation radar mission. He has published 128 research papers, mostly in JGR and GRL; and guided several Ph.D and PDF- most of them are placed in reputed institutes.

RAI, SURESHCHAND (b 1958)Professor& Head, Department of Geography, Delhi School of Economics, University of Delhi, Delhi-110007

Member of the NASI: No (YON 2018, Earth Sciences)

Dr. Suresh ChandRai is the chair Professor of Physical Geography. His research focuses on the analysis of human- environment interactions and ecological problems and their solutions for Himalaya. He has made pioneering contributions, through intensive filed and laboratory experimentation, on watershed management, wetland ecosystem, carbon dynamics and biodiversity conservation and ecotourism in north-eastern India. He has focused on the effect of land-use/cover change on the biogeochemical cycle of the soil erosion (Rai and Sharma, 1998a). Prof. Rai work on integrated watershed management has been of multidisciplinary nature and based on natural resource status and monitoring, traditional practices, hydrology, nutrient cycling and biodiversity conservation (Rai, et al., 1994; Rai and Sundriyal, 1997; Sundriyal et al., 1994; Sharma and Rai, 2004; Mishra and Rai, 2013). Rai and Sharma (1998b) have demonstrated that large quantities of sediments leave the Himalaya through its rivers and upland micro-watersheds with good forest cover and dense forests having large cardamom-based agroforestry if maintained would be hydrologically sustainable.Threats and conservation of some high altitudes glacial lakes studies provided management strategies for high altitude lakes in Sikkim (Aggarwal et al., 2017). Prof. Rai‘s group has also made significant achievements towards community-based enterprise development approaches for the conservation of Sikkim‘s unique biological diversity in major tourist destinations (Jain et al., 1999; Maharana et al., 2000a, 2000b). Apart from this, Prof. Rai also conducts applied research on groundwater hydrology and sustainable water resource management (Rai and Saha, 2017; Heena and Rai, 2020; Gautam et. al., 2020).

Member of the NASI: Yes (YON 2018, Earth Sciences)

Prof BK Rastogi has five decades of illustrious career in Seismology and Geophysical Exploration. He is credited with discovery of Bombay High. He formulated thumb rules of earthquake parameters for successful forecasting. His studies of Reservoir-Induced Seismicity are helpful for engineers. He is an Institution builder, academician and researcher. As Director General, he established Institute of Seismological Research (ISR) in 2006 at Gandhinagar which became a premier International Institute within few years. He has trained generations of Seismologists who have worked in many organisations.Prof. Rastogi has carried out significant work for seismic microzonation and hazard assessment of Gujarat state and specifically for several cities, nuclear power plant sites, LNG storage terminals and tall structures (182m Statue of Unity, hospitals, commercial complexes and industries). Such work for critical structures was previously done by foreign consultants. Rastogi's thorough world class work has saved millions of dollars and his advice for earthquake-resistant construction as well as massive public awareness efforts through print and electronic media may save lives in future earthquakes. in his recent paper he found deep lithosphere (200 km) north of the Narmada rift and shallow (100km) in the south of it from seismic tomography which is new insight in seismotectonic. Through numerical thermomechanical model of shortening between the Indian and the Asian Plates they found that the shortening rate of the high mountain areas slows down and continued convergence of India and Asia triggers the initiation of a new collision zone along Narmada rift (Nature - Scientific Reports, 2018).

Prof. B. P. Singh has significantly contributed on the Paleogene sequences of the western Himalayan foreland basin and the other coeval basins of India. His contributions are highly valuable and are pathbreaking in establishing evolution of the Himalayan foreland basin and palaeoclimates of the Indian subcontinent. He has contradicted the foreland basin model of DeCelles and Giles (1996) and suggested that the India-Asia collision occurred ~57.9 Ma (EPSL, 2003). He has interpreted that the sediments were derived from the Trans-Himalaya and the Indus-Suture zone during the early foreland basin sedimentation followed by the Higher Himalaya and the Lesser Himalaya (Geosci Jour. 2000; JAES, 2004). He has shown microbial features in the calcretes of the western Himalayan foreland basin (Sed Geol, 2007) and has estimated the level of atmospheric CO2 ~465 ppmV during late Eocene (Curr Sci, 2007). Also, he has interpreted changes in climate from wet equatorial to dry subtropical during Paleogene with the passage of the Indian Plate from the equator to 30°N latitude (Sedimentology, 2009). Contrary to established models, he has interpreted the Himalayan foreland basin sequences as devoid of deep marine sediments (JAES, 2012). He has shown that the foreland basin sediments have geochemical signatures between the active and passive margins and suggested initiation of the Asian monsoon during late Eocene (Geosci Front, 2013). He has interpreted the ~57.8 Ma transgression as forced by the collisional tectonics and the ~41.3 Ma regression as forced by the global cooling on the Indian subcontinent (JAES, 2016).

Nomination of Dr Pradeep Srivastava for the Fellowship of the National Academy of Sciences is being made on account of his substantive contributions to the understanding of fluvial architecture of rivers in diverse climatic and geological settings ranging from extremely arid to humid and from high Himalaya to its foreland elucidating their climate/tectonic connection. Dr. Srivastava‘s work explains river aggradation-incision in the Himalaya and provides event chronology of the evolution of Ganga plain and explained orogen-foreland basin linkages (Ray and Srivastava, 2010). He examined all the major rivers viz. the Ganga, Indus, and Brahmaputra and their tributaries and developed a large database combining geomorphology, sedimentology and geochronology which is unparalleled in its depth and magnitude (Srivastava et al., 2008; 2009; 2017). The work indicates that these rivers aggraded during transition from glacial to interglacial climates, and incised their valley fills during periods of higher monsoon. This concept is now globally accepted and is notable in the context of the suggestion that the erosion drives the surface deformation. His work implies that duration of the drier and wetter conditions govern the degree and phases of deformation in Himalaya. More recently, Dr Srivastava, studying lake and peat and flood deposits gave punchline result (i) Solar variability controls lake evolution in Himalaya (Srivastava et al., 2013 in QR) (ii) temperature in north Atlantic influences SW Monsoon (Srivastava et al., 2017 in Scientific Reports) (iii) SW Monsoon controls occurrence of large floods in both wet and dry Himalaya Srivastava et al., 2017 in Geomorphology).

Dr Brijesh Kumar Bansal is a professional seismologist with more than 35 years of experience as a pro-active researcher and science planner. His role in the promotion of science of seismology is reflected in the transitions from analogue to digital-real time monitoring, induction of inter-disciplinary programs for high resolution imaging of crustal structures and GPS based geodynamics. Integration of such programs is continuously enhancing our understanding of seismogenesis and seismotectonics, both in active collision zone of the Himalaya and intra-plate region of the stable peninsular shield. His vision for taking front line research is witnessed by initiating the Deep Borehole Drilling Program in Koyna towards unveiling the physics of triggered seismicity. One of the major accomplishments of Dr Bansal is creation of National Centre for Seismology, an independent Institution under MoES. Dr Bansal‘s more recent initiative to upgrade National Seismological and Geodetic Network by adding 300 stations will place India as a most advance country in seismic and geodynamic monitoring. Active fault mapping, microzonation programs are off shoot of his commitment to build earthquake resilient society. Promotion of young talent is well evident from publication in high impact journals, like Earth Sciences Reviews and Asian Journal of Earth Sciences, shedding new insight into the recent Nepal earthquake and reactivation of Kopli fault. In the back ground of proven track of professional expertise, vision for edge cutting research and above all his personal qualities make him an ideal dynamic leader to be elected as a Fellow of the NASI.

Dr. P. R. Golani‘s research contribution is outcome of his extensive field-based studies in geological mapping, structural analysis and metallogeny in the Precambrian terrains of India. The uniqueness of his scientific contribution lies in the diverse topics of research that include fault-shear zones, carbonatite, felsic magmatism, economic geology of phosphorite, sillimanite, REE, gold, base metals, hydrothermal alterations and geophysical framework of mineral deposits. Most of his research contributions contain high quality geological maps that have served to stimulate research by academia. He is credited with the recognition of submarine-emplaced felsic volcanic rocks from the Precambrian terrain of NW India; that were shown to be the causative factor in development of volcanologic massive sulphide deposits (VMSD) in Rajasthan. His research contribution on VMSD led to conferring of the National Mineral Award (1992-93). Subsequently he led to furtherance of VMSD research as National Convener of the IGCP-502. Dr. Golani has made significant contribution in formulating mineral targeting policies on strategic and REE minerals for India, as member of the NITI Aayog‘s Expert Group on REE, Member Secretary of an Inter-ministerial Committee on Strategic Minerals and as sitting Chair of the Technical Committee of the National Mineral Exploration Trust. Looking at the diverse research contribution while being in the Geological Survey of India, Dr. P. R. Golani epitomizes contribution that a field geologist can make, without being part of high research and academic institutions. I strongly recommend his candidature for award of fellowship of the National Academy of Sciences as a recognition to a field geologist Proposer: Dr. Virendra M. Tiwari, , Seconder: Prof. V.K.

Going through the entire works of Prof. S. Gupta, it has been observed that he has kept himself constantly motivated to study the Torsional surface wave propagation just after the publication of the paper entitled "Torsional surface waves in inhomogeneous elastic media" by I. Vardoulakis (1984). It was those papers (―The variation of seismic velocities within a simplified earth model, in accordance with the theory of finite strain‖- F. Birch (1939); ―The problem of the Earth's density variation‖ –K.E. Bullen (1940)) which led him to further contemplation in enriching the study. Both the authors had established a fact by their experimental work- the rigidity and density inside the earth varies as the depth increases. Prof. Gupta has theoretically studied different earth models pertinent to the propagation of various elastic waves. The particles of a medium experience a twisted motion while transmitting the Torsional waves which cannot be recorded in the seismographs as the existing ones can only record vertical and horizontal motions.

NATHANI, BASAVAIAH (b 1961), Professor-G & Indian Institute of Geomagnetism, Navi Mumbai

Member of the NASI: No (YON 2017, Earth Sciences)

Nathani Basavaiah (NB) has made fundamental geomagnetic contributions to paleoclimate, pollution assessment, impact cratering dynamics and geo-environmental studies by establishing a world-class laboratory at IIG. He was the first Indian to raise a long sediment core from supposedly meteoritic impact Lonar Crater. Using Earth‘s magnetic signatures, he brought out significant understandings of (i) shocked magnetic minerals for determination of direction of impact, (ii) long-period Deccan volcanism spanning three magnetic reversals, (iii) uplift of Pir-Panjal Range obstructing SW Indian monsoon into Kashmir valley, (iv) linking paleoclimates of Harappan civilization ―collapse‖ to global monsoon drought and, (v) urban pollution monitoring. For the first time, he has used new magnetic proxies for describing fall of the first Indian civilization and also to monitor pollution levels in Indian cities. NB‘s major outputs include 108 research publications that span the topical developments in Earth magnetism including Rock Magnetism, Paleomagnetism, Archaeomagnetism and Crustal Magnetism. Publication of a textbook on Geomagnetism: Solid Earth and Upper Atmosphere Perspectives (Springer) is acclaimed as a source of reference for students and researchers. NB is pioneer in popularizing Environmental Magnetism in India which is reflected in academy fellowships of British Council, Alexander von Humboldt, APAS, GSI, and the prestigious National Geoscience Award.

Dr. Anand K. Pandey contributing extensively to the multidisciplinary research on active-tectonics and Quaternary geology on different scale in the Himalayas. He successfully established the interplay of active tectonic-climate interaction in Late Quaternary landform growth (Pandey & Pandey, 2015; Pandey et al., 2014; Thakur et al., 2007; Thakur & Pandey, 2004) and effectively used liquefaction studies to unravel past-earthquake events in >23±2 ka old fluvial terrace around Uttarkashi (Pandey & Pandey, 2006; 2004) and ~25-26 ka old abandoned channel deposit of Yamuna (Pandey & Pandey, 2015). A first from the contemporary record is the seismites produced by the 1991- Uttarkashi and 1999-Chamoli earthquakes in the manmade reservoir sediments deposited since 1975 in Dun valley (Pandey et al., 2009); in addition to the seismites records from 1950-Great Assam earthquake and the Kopili Fault zone in Brahmaputra valley (Reddy et al., 2009; Kumar et al., 2016) and Late Proterozoic archive in Lesser Himalaya (Ghosh et al., 2012). A novel fluid inclusion study to constrain exhumation pattern along the out-of-sequence thrust in the tectonic window zone (Pandey et al., 2003; 2004; Pandey & Virdi, 2003), which is growing antiform over the seismogenic mid-crustal ramp on the Himalayan décollement. The characterization of geometry and lateral variation of décollement, using seismic data and coseismic deformation, is essential to understand the rupture propagation e.g. during 2015 Nepal earthquake (Pandey et al., 2017). The lithospheric structure across NW Syntaxial belt in Himalaya to understand seismogenesis are some other significant contributions (Chamoli et al., 2011, Tiwari et al., 2014).

Dr Devendraa Siingh has made fundamental contribution in the field of atmospheric electricity, cosmic rays, cloud formation and global climate. His remarkable discoveries related to new particle formation, ion-aerosol interactions, aerosol size distribution and nucleation events, electric field and air-Earth current density have lead to a significant advancement in our knowledge about the microphysical processes of cloud formation and global electric circuit. Dr Siingh has measured mobility spectra of atmospheric ions/ aerosol at Antarctica, Arabian Sea, Pune and a mountain station, Mahabaleshwar. He established that new particle formation (NPF) occurred when condensation sink and relative humidity is low but solar radiation and temperatures are high. At Pune observatory, the NPF events were generally preceded by 2–3 h periods of enhanced concentrations of ions and aerosols (PECIA) which are associated with katabatic winds from the surrounding hill-slopes. During PECIA, total concentrations of ions and particles become almost equal and the Boltzmann charge distribution breaks down. This mechanism explains NPF during nighttime and even at subfreezing temperatures. His observations over Arabian Sea identified highly charged large ions produced by the bubble-breaking process contribution to conductivity. He has proposed new non-oceanic atmospheric electrical index (AEI) which is capable of differentiating between the conventional and modoki La Niña and El Niño which may be useful in the future air-sea coupling studies and as a complementary to the oceanic indices and climate issues. He has published several review articles on lightning generated electromagnetic waves, lightning and climate variability, global electrical circuit, cosmic rays, TLEs Proposer: Prof. Gurbax Singh Lakhina, Seconder: Prof. Abhijit Sen Ten Best Publications: 1.

SINGH, DHRUV SEN (b 1966), Professor, Centre of Advanced Study in Geology, University of Lucknow, Lucknow

Member of the NASI: No (YON 2017, Earth Sciences)

Dr. Dhruv Sen Singh has made innovative contributions to geomorphology, sedimentology, river-hazards, water- quality, landscape-modification and monsoon-variability in Ganga Plain and Himalaya with significant academic and societal implications (Annexure 1). He has edited two books for scientific knowledge dissemination, Geopanaorama- 2009 and Diksha-2017. Prof. Dhruvsen has explained that rapid retreat of Gangotri Glacier depends on local characteristics besides global warming (Singh and Mishra-2001, Singh et al. 2016). When IPCC in 2007 reported that Gangotri glacier will disappear by 2035, Dr. Singh clarified it and contributed significantly by removing panic from society (Singh, 2009), which was later accepted by IPCC in 2010. Most significantly, Dr. Singh has explained that glaciated terrains are modified by secondary processes (Singh and Mishra 2002), that often create confusion in the identification of landforms and misleads the climatic interpretations. Such innovative findings were not accepted previously; however, after Kedarnath tragedy it was reconfirmed and re-established (Singh-2013, Singh 2014). His findings explained reasons for getting different ages for similar events in Himalaya (Singh et al., 2017). Dr. Singh has analyzed Chhoti Gandak river basin in totality for geomorphology, sedimentology, channel-pattern, morpho-tectonics, water-sediment characteristics, palynology, natural-hazards, and climate-events etc. Dr. Singh has edited a book in 2018 entitled ―The Indian Rivers: Scientific and Socio-economic Aspects‖ from Springer, the first book containing chapters on all major rivers of India. He has evolved a model to forecast the flood (Singh et al. 2015). Identification of lateral erosion as a new river-born hazard (Singh and Awasthi, 2011) is an addition to the international knowledge of Natural-Hazards.

Prof. Chakravarthi has made outstanding contributions in theoretical and experimental geophysical research besides surface dynamic studies of Land Use Land Cover (LULC), which have received international recognition in the form of US patent and research publications in leading national/International Journals. His algorithms have been found significant application in mineral and hydrocarbon explorations in both onshore and offshore regions. His invention for which the US patent office has granted a patent (6,615,139) happens to be the first-ever US patent granted to CSIR- NGRI, where he was employed previously. He has played a major role in the successful completion of many prestigious projects sponsored by ONGC, DGH, BARC etc. His new findings are i) delineation of a sub-basalt sedimentary basin in the Kutch region near Mundra-Mandvi, where the thickness of sediments is of the order of 5 km, ii) delineation of a concealed east-west trending Mesozoic sedimentary basin with sediment thickness of the order of 2.5-3.0 km between Narmada and Tapti rivers from Valod to Sendhwa-Shirpur in Deccan syneclise. These results have enabled DGH to select new blocks for exploration of hydrocarbons around Shirpur, Sendhwa, and Sakri. His recent findings on the land use land cover dynamics of Eastern Ghats, India (Ecological Indicators, v. 85, 21-36, 2018) over the last hundred years in the light of changing climate scenario have attracted the attention of policymakers to prioritize conservation strategies for the protection of RET species.

Nandakumar‘s research work at present is focused on the application of hydrocarbon fluid inclusions (HCFIs) in sedimentary rocks for petroleum exploration for which he established a non-invasive technique to determine the oil window, API gravity and chemical constituents in petroleum. The results were published in high ranking scientific journals and were also presented in the recent innovation sections in international conferences. The major finding of detecting the API gravity (a commercial value indicator of petroleum) of oils in micron sized HCFIs is granted Indian Patent in 2019. ONGC has made moves to induct the technique to further their exploration activities. Nandakumar‘s research work over the years contributed significantly to the tectonothermal history of Precambrian continental crust. Following his initial work on pressure-temperature and fluid conditions of the Kerala Khondalite Belt granulites, he made significant contributions related to regional metamorphic history, in situ zircon U-Pb dating and REE chemistry and modelling of melting through petrological and geochemical proxies which provided significant insights on melt migration in mid crustal levels and crustal heat production. The results from these works were published in high ranking international journals.My inferences are drawn from the contributions made by Dr. V. Nandakumar, based on his research publications in high indexed peer reviewed international journals of repute like the Lithos, Geoscience Frontiers, Journal of Geology, Journal of Petrology, Precambrian Research, Energy & Fuels, Petroleum Geoscience, International Geology Review, Gondwana Research etc. I certify that I am personally acquainted with the scientific work of my.

There are over 5000 citations (Google-Scholar) to Rajagopalan‘s papers. His major scientific contributions are to Depth from Defocus (DFD), Image Superresolution and Gait Recognition. He is widely credited for giving sound theoretical underpinning for DFD which is now mainstream technology. His innovative variational framework [12.1] using Markov-Random-Fields was first ever effort to tackle spatially-varying blur induced by 3D scenes. At a time when defocus and stereo were being independently investigated as depth cues, Rajagopalan proposed a novel extension [12.3] by fusing blur and disparity information to robustify DFD. He was first to analyze performance of DFD based on Cramer-Rao bound [9a.60,9b.130]. The optimum derived by nominee was later experimentally confirmed independently and used in system design by other groups. Patents on DFD from Sony, Apple, Nokia, Panasonic, Adobe, Canon have extensively invoked nominee‘s papers. His work on discontinuity-preserving yet computationally efficient superresolution of number plates of vehicles [12.4] has drawn wide-attention from both vision and transportation communities. Very early on, he revealed how higher-order correlations can be elegantly harnessed for superresolution of low-resolution face images in his well-cited work [12.5]. He is among the first to generalize superresolution to multi-view stereo leading to high-resolution image and depth-map [12.8, US-patent 8339470]. His efforts on gait recognition using hidden Markov models [12.2] is a prime example of model-free approach to gait and marks a seminal milestone towards human identification from a distance. [12.2] has been regularly used as baseline for comparison and is among the most-cited by gait community. Proposer: Prof. Subhasis Chaudhuri, Seconder: Prof. Bhabatosh Chanda Ten Best Publications: 1.

Dr. Sandip Ghosh Chowdhury‘s major contribution lies at the area of phase transformation in developing new steels.He was involved in the development of a cast steel having improved silt erosion resistance for underwater components of hydropower stations in the Himalayan region. Through the alteration of composition, Transformation- induced plasticity (TRIP) effect in the steel has been introduced. Prototype components were manufactured and field trial during the monsoon season was successfully carried out.Partitioning of alloying elements have been employed to develop a two phase (austenite + ferrite) twinning-induced plasticity (TWIP) steel for automotives. The steel with high strain hardening could be cold rolled to 1.5mm thickness. In the similar line, presently, a Fe-base high entropy alloy was developed through alteration of chemical composition with tensile strength x total elongation upto a value of 35GPa%. Investigation is being carried out to replace stainless steel with this for naval applications. A new composition of Grinding media balls for cement industry has been developed. There are quite extensive wear of grinding media balls and the new steel composition as well as the heat treatment schedule developed showed an improvement in wear resistance; it leads to lesser consumption of these balls by nearly 33% in actual operation.Another wear resistant steel has been developed through quench-and non-isothermal partitioning process in the hot strip mill route. This steel is presently being imported in India. The development work is quite successful at the pilot scale level and commercial production is planned by the sponsor. Proposer: Prof. S. P.

The research activities of Dr. Das are focused towards the intelligent experimental observations of interfacial interaction and numerical modelling of two-phase flow using open source and commercial codes. His interest to the study of multiphase flow, is within the phase change and adiabatic domain of gas-liquid mixture. He has developed population balance model based transition criteria for homogeneous to well-separated gas-liquid interface which has applicability for bubbly, dispersed bubbly as well as droplet flow dynamics. His proposal for diffused interface concept in Lagrangian smoothed particle hydrodynamics [1] revealed fluidic physics behind droplet manipulation, translation, uphill movement, joining and splitting in electrowetting and magnetohydrodynamic framework. To understand phase change heat and mass transfer in mesoscopic scale, Dr. Das has developed innovative ghost particle based algorithm which can successfully modeled nucleate and film boiling situations. He has extensively worked on interfacial entrainment like rotational vortices, jet impingement and annular co-flow. His experimental efforts towards gas-liquid interface have led to intelligent optical and electrical conductivity based probe developments. He showed experimentally that using intelligent surface design heat transfer coefficient can be doubled as compared to plane heating surface [2]. His recent studies towards bio-fluidics have led innovations like indigenous Pranavayu ventilator, physical exhaustion kit based on saliva and left ventricular assisted device. As a whole, his research is catering the domainofenergy,water and health care by and large. Das and Das, 2009, Langmuir, 25(19), 11459-11466.

Prof. Ganguly has significantly contributed in the area of complex systems and complex networks for the past 20 years. He has also contributed in development of various machine learning, natural language processing and information retrieval techniques applicable to such complex networks. His primary area of application has been online social network, which is a classic example of dynamic, complex network. Some of his contributions are noted below. (a). His work on identifying spams/unreliable users on social network is one of the earliest works and the ranking algorithm developed to demote such users has received heavy citation. (b). He also developed realistic models to capture the dynamics of opinion about certain events unfurling over social networks; further he also studied how opinions are injected in the social network from outside to shape public perception. (c). He built detailed summarization techniques to extract useful and reliable content from the user-generated content on social media posted during disaster. Beyond social networks he has recently proposed deep network generation model to generate feasible, synthesizable but hitherto undiscovered molecules, where molecules has been treated as multi-graphs. His team performed network analysis of Indian Railway System, which provided important and accurate insight regarding the accident-prone regions within India. The entire analysis has been possible as he developed theories related to centrality, community formation, growth and resilience of complex networks. Summarizing, Prof. Ganguly is one of the most influential researchers in the area of social computing and complex networks in India, which prompt me in nominating him.

Dr. Ghatak is nominated for his research on soft material mechanics: adhesion, friction, wetting, instabilities and fracture of soft objects, elasto-capillari effect at solid-liquid interface, heterogeneous nucleation and particularly for his creative experiments for learning engineering principles prevalentin nature.His most notable contributions include methods for making three dimensionally oriented microfluidic channels in elastomers and gels7,10, design of bio- inspired adhesives embedded with fluid filled micro-structures2,6,8, multiple tip syringe needles, hierarchically structured surface for heterogeneous crystallization of macro-molecules4, design of flexible, aspheric optofludic lenses, and several others, all leading to significant insight into several physical phenomena. For example, Animangsu‘s work revealed the effect of sub-surface fluidic vessels and micro-structures on adhesion, a mechanism relevant for understanding the workings of adhesive pads present at the feet of many animals2,6,8. His work on elasto- capillarity revealed how curvature of a soft surface causes its deformation3,5. The work on fracture in the context of puncturing of a soft gel led to the understanding of how geometry of the puncturing tool and its rate of insertion into the gel affect the mechanism of fracture, a result relevant for understanding the working of proboscis of many insects like mosquito. His work on optofluidic lenses led to a bottom-up method for making aspheric optical lenses suitable for variety of high-end microscopy applications. To summarize, Animangsu‘s work involves simple yet thought provoking experiments, ones, which are rich in physical insights yet yields results, which have the potential of many engineering and scientific applications.

GUPTA, SHALINI (b 1980), Associate Professor, Indian Institute of Technology Delhi

Member of the NASI: Yes (YON 2021, Engineering Sciences including Engineering Technology)

The nominee's pioneering research contributions can be broadly classified into the following areas: Development of in vitro diagnostic bioassays and antimicrobial systems for infectious disease management Design of electrically interfaced microsensors for colloidal manipulation and materials fabrication on a chip In the area of infectious diseases, the nominee has studied the role of nanomaterials for fabricating simple and affordable bioassays and biotherapeutics. Her most significant achievements in diagnostics include (i) a point-of-care bioassay called SeptifloTM to detect bacteria in blood under 10 min for early bedside diagnosis of sepsis, and (ii) an impedance-based label-free assay for rapid identification of resistant bacteria under 30 min. Both these approaches significantly reduce the bacterial diagnosis time (by up to days) as they do not rely on cell/DNA doubling which are inherently slow processes. In therapeutics, the nominee is the first to demonstrate a multiscale drug delivery platform that co- eliminates cancer and bacterial infections in cancer to curb anticancer-antimicrobial drug resistance. In the area of electrical microsensors, the nominee has made seminal contributions to the investigation of AC electrokinetic phenomena for studying colloidal interactions and assembly. This has led to the realization of several novel functional architectures including optoelectronically active quantum dot microwires, magnetically responsive live mammalian cell 2D arrays and single bacterial cell patterning for subpopulation heterogeneity analysis. She has significantly shown that low conductivity zwitterionic buffers can enhance impedance signal outputs by several folds, enabling particle detection at unprecedentedly low concentrations without using complex chip designs and/or particle enrichment strategies.

Prof. I. N. Kar has worked extensively on Lyapunov stability based controller design, time-delay systems, robotics, H- infinityoptimalcontrol,and contraction theory.His main contributions are as follows. He proposed a novel robust adaptive controller for trajectory tracking of Euler-Lagrange systems (mobile robots and snake robots) in the face of system uncertainty and time-delay. This has resolved the critical problems of developing tracking and robust controllers for Euler-Lagrange systems. He designed and implemented the H-infinity based robust control law for flexible structure systems to reduce the vibration of a structure against disturbances like winds and earthquake motions.These results encourage the use of mathematical control theory in inter-disciplinary areas. He solved the stability and synchronization problems of networked nonlinear systems using contraction theory which exploits the incremental behavior of trajectories with respect to each other and provides an alternative way for stability analysis. He characterized a new class of systems which shares a common quadratic Lyapunov function for robust stability analysis. Furthermore, a robust controller design problem is formulated as an optimal control problem for a classo funcertain non linear systems. He adopted a fuzzy logic based function approximation property in designing various adaptiv econtrol laws for electrica land mechanical systems. He introduced a novel thermal sensation index based control scheme to improve the performance of air-conditioning coaches of Indian Railways. An Indian patent has been granted for these findings and the technology has been transferred to Modern Coach Factory (Rae Bareli) and RDSO, Indian Railways for future deployment.

Prof. Kar currently holds a Champa Devi Gangwal Chair at IIT-Kanpur. He is one of the leading inventors/scientists/academicians in the area of material/product development for supercapacitors, batteries, PEM fuel cells, water purifier, MBT-Arjuna,seal of PFBR/FBTR.Prof. Kar synthesized several nanostructured carbons from waste. He also made several types of high-quality carbon nanotube (CNT) using the optimum process conditions in the simple CVD technique. He also used defect-engineered self-assembly to produce a three-dimensional nanohole- structured and nanoparticle embedded porous graphene/CNT/cauliflower CNTs (one-of-the darkest man-made materials having absorbing capacity (> 99.5%) in the whole UV-Vis-NIR range), simple solvent casting method to make nano/micro polymers and multi-doped ferrite/titania-based nanostructured composites having ~ 99% efficiency in water purification.The strategies for selecting materials and their manufacturing aspects of the storage and conversation devices should be optimal. The developed approach by him to improve performance is a multi-level optimization problem as each component has its specific properties, sometimes opposite characters. Being a multi-objective problem, the proposed formulations are solved by hybrid materials (metal-doped Li-phosphate/platinum). Flexible devices are gaining immense interest among researchers/industries. But the energy-density of flexible batteries/supercapacitors remains low as there is a limitation regarding the thickness of materials and therefore the total electrolyte loading. The performance is also restricted by the parasitic chemical reactions and mechanical breakdown due to swelling during charging-discharging. He made micron-sized 1-D and 2-D batteries. -Finally, few of his inventions have been translated to IV-USA (CNT coated fibers/Hydroxyapatite), ARIL-Lucknow (Supercapacitors/Fuel-cells/Batteries), MEL-Chennai. (MBT-Arjun Tank), SNC-Kanpur (Graphene/Nanopolymers), and IGCAR- Kalpakkam (PFBR/FBTR). Proposer: Prof. Gautam Biswas, Seconder: Prof. Debashish Chowdhury Ten Best Publications: 1.

The contributions of Prof Kumar can be summarized as follows.―Power-on-Demand‖ micro-power generators: Combustion-based micropower generators have nearly zero-recharging time, no environmental disposal hazards and high-energy densities (~ 20-50 times). They are expected to supply Power-on-Demand for MEMS and remote sensor applications. Multiple prototypes with 1-24 W power range and ~ 6% conversion efficiency have been developed [J11,J19,J29,J60,J68].Development of flameless gas-turbine combustor: Internal recirculation preheats and dilutes the fresh reactants, suppressing CO, NOx, and acoustic emissions significantly with uniform temperature distribution to improve thermal efficiency and component life [J1,J8,J18,J38]. Accurate modeling helped develop a can-type flameless GT combustor operating with liquid fuels with nearly zero CO and NOx emissions. Flame propagation at engine-relevant conditions: Fuel-air mixture attains 20-30 bar pressure and 700-800 K temperature in IC engines and gas turbines before ignition. Existing methods lead to erroneous measurements at these conditions due to non-linear flame-stretch dependence (~±30%) [J37]. Indigenously developed diverging channel method accurately measures flame propagation characteristics at these conditions. Accurate measurement is important for development of new kinetic models, and turbulent combustion modeling [J10,J20,J22,J25,J30]. Machine- learning models in combustion: Combustion modeling is governed by stiff-chemical reactions and detailed simulations are impossible for practical systems. This is the first machine-learning model in combustion field, which instantly predicts the combustion characteristics of a complex combustion system [J10,J20].Additional contributions: Mitigation of compressor instabilities, Pulse detonation engines, Lifted flames, Combustion instabilities in solid rocket motors, Supersonic combustion modeling, development of radiative heat transfer probes, Combustion instabilities and their control.

Dr. Bhanu Pratap Singh has made outstanding contributions in the development of specialized carbon products for industrial and strategic applications. Has published 121 research articles with citations > 6500 and h-index of 43 as per Google Scholar.Using a novel technique, carbon nanotubes (self-prepared) have been used for the preparation of free- standing flexible binder less paper which has led to the development of high capacity anode (Specific capacity of 500mAh/g as against 372mAh/g for conventionally used Graphite (US Patent 10,003,075) for LiB. Another glaring application of free standing CNT paper has been made by innovating a novel technique (US Patent 10,400,074) wherein this paper has been employed to prepare CF-CNT Composites possessing 30% higher strength than CF epoxy Composites (CF45wt%+0.5wt%CNT as against 50%CF and 30% lower strength), now being exploited by DRDO.In collaboration with DRDO, for Stealth Aircraft, a new technique has been invented enabling development of light weight (1.25gm/cc) composites with 50wt% uniformly distributed CNTs (Indian Pat.1793DEL 2011).

BALANI, KANTESH (b. 1978) Professor, Indian Institute of Technology Kanpur

Member of the NASI: No (YON 2020, Engineering Sciences including Engineering Technology)

Dr. Balani‘s scientific contributions focus on developing multifunctional hip-joints architectures: (i) He has developed functionally-graded material that impart required surface bioactivity with bulk-toughness to the implants for potential hip-joint replacements (Mat. Sci. Engg. C, 2012). He has conceptualized non-toxic nature of carbon nanotube (CNT) reinforcements (Biomaterials, 2007 & Mat. Sci. Engg. C, 2010) promoting substantial toughening and enhancing bioactivity of hydroxyapatite (HA)-based biocomposites. He has led with the development of porous HA-based scaffolds (Ceram. Intl., 2017 & Adv. Engg. Mater., 2018) with multifunctional capabilities (i.e. antibacterial and antioxidant efficacy with Ag, ZnO and CeO2 additions, J. Biomater. Appl., 2013, Mat. Sci. Engg. C, 2018 & Wear 2018). (ii) He has qualified bacterial de-adhesion via assessing the protein-adhesion of grampositive S. aureus on real- life bio-surfaces (i.e. ultra-high molecular weight polyethylene (UHMWPE), HA, stainless steel (SS) and Ti-6Al-4V) (J. Mech. Beh. Biomed. Mater., 2017 & Mat. Sci. Engg. C, 2017). Tribological effects of SS and Ti-6Al-4V are complemented with finite element modelling under various reciprocating geometries for mimicking real-life joint movements (Nanomater. Energy, 2021). To complete the story, he has elicited the de-adhesion events of bacterial protein on these biosurfaces using molecular dynamic simulations (ACS Biomater. Sci. & Engg., 2020). (iii) His efforts on fabricating ZnO reinforced antibacterial UHMWPE (Mat. Sci. Engg. C, 2016), enunciating interfacial phenomena (J. Phy. D: Appl. Phy., 2014, Eur. J. Mechanics A/Solids, 2017), and effect of mandated UV and gamma- sterilization of UHMWPE as acetabular-cup polymeric-liner (J. Mat. Res. Tech., 2021) are highly appreciated by scientific community.

The nominee is among the foremost experts in formal verification in India. He has made fundamental contributions to the theory and practice of scalable formal verification of computer systems. Software verification techniques developed by him have been deployed in tools in BARC, Microsoft Research and Tata Consultancy Services. Among hardware verification techniques, he developed word-level symbolic trajectory evaluation (STE), which enabled STE (an industry-strength verification technique) to scale to designs with wide datapaths for the first time. This technology has since been transferred to Intel.Through a series of papers since 2013, the nominee and his collaborators achieved a major breakthrough in constrained sampling and counting. They developed a class of algorithms that scale to problems involving constraints with hundreds of thousands of variables, and yet provide strong approximation guarantees. Their work bridged a long-standing gap between scalability and provable precision in this important area, and has led to several derivative work by others.The nominee and his collaborators have also made fundamental contributions to Booleanfunctional synthesis, with applications to reactive controller synthesis, cryptanalysis, circuit repair etc. Despite complexity-theoretic barriers, they pioneered the design of practically scalable algorithms for this problem. Their work has also elucidated deep connections between knowledge representation and complexity of synthesizing Boolean functions from relational specifications.The nominee has also contributed to improving long- standing the oretical bound sindisambiguation and determinization of Büchi automata. He has also contributed to generalizing the classical Łoś-Tarski Preservation Theorem in model theory. Proposer: Prof. R. K. Shyama Sundar, Seconder: Prof. S. Sudarshan Ten Best Publications: 1. S.

Dr. G. Madhusudhan Reddy has made significant and remarkable contributions towards the development of critical welding technologies required for wide spectrum of defence hardware. Important components tackled by him were made up of special steels, superalloys, titanium alloys and aluminium alloys. The detailed scientific understanding and indigenous development of brazing and welding technologies for these materials reduced the dependency of India on other nation satcritical Juncture.Dr. Reddy contributed significantly to the structural Integrity of joints in Aerospace components, as the Chairman of a Weld Certification Committee. Dr. Reddy‘s exceptional R&D acumen coupled with dedicated and consolidated efforts led to these exemplary achievements and gave the much-needed fillip for self- reliance in welding technology for Indian defence. Dr. Reddy was also instrumental in developing suitable manufacturing technologies (such as welding, forming, machining and protection against SCC) for the DMRL- developed low-alloy ultrahigh strength steel with toughness and strength comparable to the expensive Maraging steel, that enabled DRDO to successfully realize several critical defence hardware such as missile motor casings and armoured vehicles. His initiative, leadership, and dedicated efforts have resulted in the establishment of Friction-Stir Welding (FSW) and processing technologies, elevating DMRL to a unique position in the country in the manufacture of defence components. FSW has been employed to join Indian Reduced Ferritic Austenitic Martensitic (INRAFM) steel to eliminate delta-ferrite in the weld zone that is detrimental to mechanical properties.

Design and development of fuzzy-focal receivers of large aperture solar parabolic dish systems for process heat and power generation applications; some of these point focus solar collector configurations have reached to the stage of complete commercialization by our industrial partners. The designs on solar parabolic dish collectors are being used in India and abroad by the academicians and solar companies. An atlas for concentrating solar power plants was proposed, which became very important decision making tool for Indian solar industries for implementation of Mega Watt scale plants. The proposed artificial neural network models to estimate the solar energy resources and to arrive viable engineering solar systems at about 53 locations covering entire Indian indigenous communities. The studies on 4-E (Energy-Exergy-Environment-Economic) analysis of solar thermal aided coal-fired power plants have explored very comprehensive options for both feasibility of hybridization of energy sources and viability of energy & environment technology solutions. Another very significant contribution is the design and development of secondary concentrator based trapezoidal cavity receiver of Linear Fresnel Reflector system; a pilot plant was installed in a remote residential school campus (Pathashaala-KFI, Krishnamurti Foundation India) and it can fulfil standalone community‘s energy requirements. The development of high-yield multi-tray solar desalination system based on latent heat recovery concept for potable water production from seawater resulted in low cost energy solutions for safe drinking water production in indigenous and coastal communities.

In India, Dr. Munna Khan, Professor has pioneered bringing advanced Engineering techniques to understand the medical status of aviation pilots in real time and dynamic mode. Towards this objective, he has brought in a link between high level technological institutions with the domain of aviation medicine and its field applications. This collaborative activity originated by Dr. Khan has been extended to help in more practical oriented use of electrical impedance plethysmography in organizations dealing with aviation medicine in USA. He has significantly contributed towards increasing interaction of aviation medicine professionals in India with their counterparts in USA. Dr Khan has introduced various new dimensions in bio-instrumentation for health care and thereby significantly advanced human welfare. The specific contributions are in conceiving the concept for non-invasive quantification of lung edema onset and distribution. It not only shows the presence of fluid but it roughly estimates the amount of fluid accumulation. This particular methodology has helped in reducing morbidity in persons who go to high altitude. Also the innovative technique and instrumentation has value in hospital medical practice. Dr. Khan has also pioneered bringing advanced technique to design and develop the Psychoacoustic device using Indian resources. It produces signal at inaudible frequency range and could have applications in the use of non-lethal weapons. The developed psychoacoustic device may attack during the war with the intention of altering mental states of their enemies.In view of his outstanding thirst for scientific knowledge and exceptional professional skill, I strongly recommend his case for consideration for NASI Fellow.

Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion. For sustainable system, it is necessary to use the renewable resources and reduce energy consumption. Prof. Kumar‘s research is focused on development of semiconductor materials and energy efficient devices such as Sensors, LEDs and Solar Cells. During his stay at Bharat Electronics Ltd., he has developed epitaxial layers of In-Ga- N family of compositions, multilayers of GaN/InGaN, band gap engineering by modulation of In-Ga-N composition. This work has led to the fabrication of blue emitting InGaN/GaN multiple quantum well LEDs. The power consumption on lighting is around ~18- 20% of total power consumption and using GaN LEDs power consumption can be reduced. He has also demonstrated real time heavy metals ion sensors based on GaN transistors. Air quality has degraded worldwide and in particular, developing countries due to industrial/vehicular pollution and solid waste and its decomposition. In this direction, Prof. Kumar has demonstrated large area MoS2 layers by chemical vapor deposition method and demonstrated ultrafast and reversible sensor selective to NO2 gas at room temperature under UV illumination. The candidate‘s group is the first one to demonstrate successful growth of MoS2 nanowire network for gas sensing applications. He has also fabricated formaldehyde sensors to monitor the seafood freshness. Prof. Kumar is coordinator of Centre for Advanced Scientific Equipment, IIT Jodhpur. He has published 115 research articles in peer-reviewed journals with 2000 citations. He is also founding member and former chair of INYAS.

MUKHERJI, SOUMYO (b 1967) Professor, Department of Biosciences and Bioengineering, IIT Bombay

Member of the NASI: Yes (YON 2020, Engineering Sciences including Engineering Technology)

Prof. Soumyo Mukherji has been very active in development of low cost sensors and instrumentation systems for quite a while and has significant contribution to this area that can be credited to him. He has worked in the area of MEMS devices, which led to a patent for the development of a microheater which may be used to detect explosive vapors. This has led to the incubation of a startup, along with colleagues, called Nanosniff. He has also worked extensively on optical and electrochemical sensors for water quality and monitoring of health. His students have been awarded the BIRAC-SRISTI GYTI award on two consecutive years for the work done under his tutelage. His primary focus is on developing nanostructure enabled optical and electrochemical sensors. The optical sensor platform he has developed using nanoparticle decorated, U-bent optical fibers, functionalized with appropriate receptor molecules can be deployed for point-of-use detection of bacteria in water, metallic contaminants like mercury, lead and copper in soil, water and food, and disease marker proteins in serum. Recently he has patented methods to detect anti-microbial resistance in bacteria, antibiotic residues in food products, etc. The most exciting development off late in his lab (patent filed) is a technique by which using the interaction of bacteria or viruses with metallic nanoparticles, distinction can be made between the presence of bacteria or virus in a sample. This has been a challenge to researchers worldwide and this development will surely go a long way in infectious disease control. Proposer : Prof. J.S.

Prof. Suparna Mukherji has undertaken innovative research related to bioremediation and the treatment of water and wastewaters. She elucidated and illustrated the significant potential of naturally occurring microorganisms for degradation of recalcitrant and hazardous organic compounds (HOCs). She has developed and optimized the performance of innovative treatment processes by bioaugmenting with novel microorganisms and by utilizing novel microbial associations. Prof. Mukherji demonstrated the diverse benefits of association between sessile algae and oil degrading bacteria and a patent was granted for this process. These microbes were shown to degrade toxic, mutagenic and carcinogenic components in oil as sole substrate.

Prof. Singh has successfully innovated, developed and publicized Environmental Geotechnology, a subject, in the realm of Geotechnical Engineering education and practice. He has successfully demonstrated the importance and relevance of revising classical concepts to imbibe the influence of various environmental factors that govern the interaction of contaminants with geomaterials and their degradation or up-gradation in the long-run. His research is fundamental, interdisciplinary, and focused on addressing challenges being faced by society and industry. Some of his fundamental contributions are: (i) porous media characterization using various energy fields and capturing the mechanisms that occur due to this interaction, in a nondestructive, noninvasive and economical way, (ii) development of methodologies for determining chemical, mineralogical, thermal, electrical and biological properties of geomaterials, (iii) characterization of unsaturated soils, (iv) multi-phase geomechanics (methane gas hydrates, freezing response of geomaterials) and (v) valorization of industrial by-products, which are an amalgamation of the concepts from basic science, engineering and technology. His vision about the importance of the above-mentioned research areas has led to the launch of an International Journal Environmental Geotechnics, development of a state-of-the-art Environmental Geotechnology Laboratory at IIT Bombay, which has been recognized as the Laboratory for Geoenvironmental Research & Innovation (LeGReIn) by the CII, New Delhi. He has supervised 39 Doctoral dissertations (and 7 are ongoing) and has been successful in filing 33 patents out of which 15 (including 1 US) patents have been granted.

Prof. Singh has significantly influenced the field of molecular simulations and thermodynamics and accelerated the accurate prediction of material thermophysical properties. Prof. Singh has made path-breaking contributions to the fundamental insight into the phase equilibria and interfacial properties of fluids and fluids confined in nanopores. He has developed an algorithm to calculate accurate virial coefficients of fluids (PRL 2004), fueling the liquid state theory's growth. Prof Singh has made ground-breaking contributions by developing molecular simulation algorithms to understand phase transitions of nanoconfined fluids. For the first time, he has also quantified the critical pore size above which fluids retain their bulk behavior. His work has provided a means to address a long-standing challenge of representing nanoconfined fluids' properties in an analytical form. (JPCC 2009; JPCB 2010). He has developed methodologies to study the melting and crystallization of nanoconfined fluids in recent years. This has led to discovering new phases of ice at high pressure (JPCC, 2020) in nanopores. The nominee, over the years, has also made ground-breaking contributions in developing molecular models( JCC 2015, 2017; APL 2017; JPCC 2017), and material screening framework for screening CO2 adsorbents from flue gases (JPCC 2015, 2016). Prof. Singh extended his understanding of surfaces to create a variety of materials for oil-water separators and also developed a technology for an efficient battery separator (US Patent 2019). Prof. Singh also translated the work by copyrighting s/w platforms developed by his group, which is now used by few industries for material and drug discoveries. Proposer: Prof. Santosh K.

SINGH, RAM KUMAR (b 1953), Visiting Professor IIT-Bombay, Mumbai

Member of the NASI: No (YON 2020, Engineering Sciences including Engineering Technology)

Dr. Ram Kumar Singh is an active researcher dedicated to realization of indigenous technology development for nuclear reactor design, safety assessment and national security applications. His major contributions have been first of its kind in the frontier nuclear science and technology areas which so far were available to only a few select developed countries. He developed indigenous finite element code SHOCK-3D for shock wave propagation due to underground explosion induced gas cavity growth and the resulting spall, fracture and crater evaluation. The near field hydrodynamic and inelastic formulations with equation of states in different regimes were useful for the near and far field regions to explain the effect of local geological formations on the test observations. His published work on US Baneberry-1970 nuclear test first 3D simulation is extremely noteworthy for explaining the reported venting due to explosion induced fault movement in the complex geological strata, as acknowledged by the international scientific community. The seismic signal analysis for different rock formations are his major contribution relevant to national security to affirm India‘s strong footings for its present strategic position within the global community. His other distinguished contributions are in-house computer code development for fluid-structure-thermal interaction, inelastic impact shock analysis of nuclear structures, components and systems, experimental / numerical stress analysis for reactor containment structural and thermal hydraulic safety evaluation, tsunami studies, passive recombiner development, its qualification and technology transfer to ECIL and development of severe accident management guideline for Indian nuclear plants in case of extreme external and internal events.

Dr. Biswas has made fundamental contribution to our understanding of formation, functional & mechanical properties, and applications of high entropy materials (HEMs), an emerging class of multicomponent material. As compared to conventional metallic alloys, in paradigm shift, multicomponent alloys with each component having equal weightage, have changed the concept of alloy design worldwide. His research has impacted materials and engineering community in three distinct directions. He conceived multicomponent alloys by extending thermodynamic models of binary and ternary alloys to five and more components and discovering new alloys with superior functional & mechanical properties. In a breakthrough, he coupled this with optimization of a large number of possible surface adsorption states through machine learning algorithms to discover novel high entropy alloy (HEA) catalysts for green energy applications significantly impacting energy research in the world. The discovered catalysts (AgAuCuPdPt) and (CoGaFeNiZn) show exceptional selectivity and tenability, raising hope of universal catalyst for energy and environment applications. The sensor device fabricated using 2DMoS2-decorated with nanoclusters of AgAuCuPtPd and (TiZrVNiCo) have resulted in enhanced gas sensing response. He has employed similar approach in designing and translating to prototype level of self-lubricating nanostructured HEM bearings. His persistent efforts led to understanding of lattice distortion on mechanical properties of these alloys.His sustained research has guided the Indian Space Research Organization scientists to develop HEM-based prototypes for liquid hydrogen interstage storage tanks in cryogenic engine. Recently, he employed unique green route for beneficiation of electronic waste to nanocrystalline HEMs and applications in energy and environmental technologies.

During his last 17 years of research career Prof Das has made some outstanding contributions in the field of functional ceramics. He has invented, scaled up, implemented and commercialized a nanoparticle based novel chemical mechanical planarization (CMP) technology for processing of single crystal bulk SiC substrate, which is a significant contribution towards the development of SiC based power and optoelectronic devices. His work on CMP of SiC in Sinmat Inc., Gainesville, FL, USA had won 2009 Frost & Sullivan North American Excellence in Research of the Year award in the field of advanced semiconductor surface modification, 2008 R&D 100 Award and a granted US patent (US Patent Number 8, 557, 133 B2, 15th October 2013). The work was selected by an independent judging panel and editors of R&D Magazine as one of the 100 most technologically significant products introduced into the marketplace over the past year. Sinmat Inc. has been using this technology successfully for production of CMP slurries since 2008 and generating lot of revenues. Development and transfer of CMP technology for single crystal bulk SiC, III-V nitrides, and MCT/CZT substrates using indigenous materials, are significant contributions towards development of advanced electronic devices for Indian defense applications (Patent Application Number – 3471/CHE/2013). Dr Das‘s work on BZT ceramics is another important contribution towards development of MW window for fusion energy application (Patent Application Number – 1591/CHE/2013). I strongly believe he is a very qualified technologist and recommend him for the Fellowship of The National Academy of Sciences (NASI). Proposer: Prof. A. K.

Skewed datasets challenge most learning algorithms. The nominee pioneered the Twin SVM, which is insensitive to relative class sizes. It has nearly 870 citations, and is the subject of at least 5 survey papers in reputed journals. He is first author of a Springer book on the subject. Single cell mRNA sequencing yields gene expression levels in thousands of individual cells. The nominee‘s jointly innovated algorithm detects small rare cell groups, and significantly outperforms state-of-the-art on speed and robustness. This Nature Communications work can potentially be used to find a few tumour cells in a blood drop; it discovered a rare subcell type in a public domain dataset. He pioneered new theory for learning small models; the Minimum Complexity Machine yields models 3-100x smaller than SVMs, but with comparable accuracies. His papers (2 conferences & 1 journal) received best paper awards. He co-authored a popular textbook on optimization. He originated the EigenAnt, the first Ant Colony Optimization (ACO) algorithm with stability and convergence proofs. His group's EigenAnt based router is possibly the first ACO on VLSI anywhere. EigenAnt was an invited keynote at IEEE SSCI, Singapore, 2013 and featured in HT Mint. He has a US patent on A/D conversion; another on assessment of pronounciation abilities; a third on optimization-free chromatographic estimation of mixtures has been approved by USPTO. Some of his algorithmic trading models are deployed by Marketopper Pvt. Ltd. He developed and transferred low loss SAW filter design software to Motorola, Scottsdale, and later to Chicago Telecommunication Systems. Proposer: Prof. Surendra Prasad, Seconder: Prof. Nikhil R.

Prof. James Raju is the first person to develop microwave dielectric resonators in India. He studied how materials for these applications exhibit high dielectric constant with low dielectric loss and low temperature coefficient of resonant frequency and explained it on the basis of their structure, Lorentz field factor, degree of covalancy and their lattice dynamics as derived from far IR reflectivity spectrum. Then he proceeded to make thin films of ferroelectrics in their paraelectric state to study their voltage dependent microwave dielectric properties to develop crucial tunable microwave devices. He succeeded in developing tunable varactors, filters and phase shifters using these films again first time in India. The necessary microwave on wafer probing based measurement techniques for measuring broadband microwave tunability in these films were established using patterned microscale structures. He is extending these techniques for multilayer multiferroic thin films for electric field tuning of magnetic properties as magnetic structures can‘t be miniaturized to micron size scales. By extending these techniques, he is able to achieve High Overtone Bulk Acoustic Resonators (HBAR) which gives resonance peaks that give Q values as high as 35000 while the device dimensions are 100micron x 100micron. With further modification he is close to achieving FBAR. His most important and recent contribution is reducing processing temperature of these films to 300oC using a laser based annealing process so that these films for the first time became compatible with polymers and nanoelectronics. He filed for a patent. With this process he achieved reduced leakage current in nanocapacitors. Proposed : Prof. Anil K. Bhatnagar, Seconder : Prof. M.J. Swamy Ten Best Publications: 1.

Member of the NASI: No (YON 2019, Engineering Sciences including Engineering Technology)

Dr. Kshetrimayum is a leading educator and researcher in the area of MIMO wireless communications. He authored the popular textbook on ―Fundamentals of MIMO wireless communications‖ (Cambridge University Press, 2017). He co-authored a book on ―MIMO wireless communications over generalized fading channels‖ (CRC Press) and it is the only reference book on the topic. His area of research in the MIMO wireless communications is on Spatial modulation (SM) and its advanced versions. He has made several original proposals for performance improvements in MIMO wireless. He proposed spectral and energy efficient modulation schemes viz. Optical generalized SM, optical enhanced SM, and optical improved quadrature SM for FSO communication with reduced implementation cost [IEEE Transactions on Communications (TCOM1)]. He also proposed a new method for cellular communication which employs hybrid FSO/RF and it combines the benefits of both RF and FSO channels (TCOM2). He reported the first integration of Optical SM with transmit source selection in free-space optical (FSO) with significant performance improvements (IEEE Communications Letters). He also co-authored a book titled ―Advanced spatial modulation systems‖ (Springer Nature) and it is the first reference book on the topic. Another area of his research is on closely packed MIMO antenna arrays. He reported MIMO antenna arrays whose inter-element spacing (IES) < 0.076λ which is much lesser than the traditional antenna array‘s IES of 0.5λ. His closely packed MIMO antenna arrays have acceptable values of MIMO antenna performance metrics such as mutual coupling, envelope correlation coefficient, diversity gain and channel capacity loss.

The candidate has contributed immensely in various applications of polymers such as membranes in direct methanol fuel cell, microbial fuel cell and support for catalysts (sulfonated conducting polymers). In direct methanol fuel cell, he has achieved a high performance in terms of power generation by using low cost PVDF and PVDF-co-HFP based membranes. A novel catalyst support system based on sulphonated conducting polymers is developed and by using this support system, he is able to get much better dispersion of nanocatalyst, leading to much improved electrical efficiency. For microbial fuel cell, he used low cost catalyst such as nickel, alumina, cobalt, iron and used low cost polymers such as PVDF, PVA, polyolefins and able to generate power much higher than the reported value in the literature along with substantial reduction of COD value by 90 %. These low cost catalyst and membranes will definitely be useful in the commercialization of MFC technology especially in waste water treatment. For treatment of diabetes, usually insulin is injected. As insulin injection is painful, an alternate route of insulin delivery is oral, provided one should take precautionary measures of protecting insulin under harsh acidic conditions of stomach. He has also developed some novel core-shell insulin delivery system based on natural biodegradable polymers in which bioavailable insulin is sufficiently high (11.5 %) and this value is comparable to those reported in the literature. The candidate has also developed some vegetable oil especially linseed oil based polymers via cationic polymerization for application as vibration dampers. Proposer: Prof. Surya K.

MAULIK , UJJWAL (b 1965), Professor Department of Computer Science and Engineering, Jadavpur University, Kolkata

Member of the NASI: No (YON 2019, Engineering Sciences including Engineering Technology)

In pattern recognition and bioinformatics, Ujjwal‘s international visibility is already evidenced from his induction as Fellow of INAE, IEEE, and IAPR. He has earlier received Humboldt Fellowship and ICTP Senior Associateship. He has 350+ publications including nine books with 14000+ citations (h-index = 49, i10-index = 150, Google scholar). Ujjwal‘s important contributions, made while being part of a State University and done largely in-house with his students, include cancer gene marker identification in data-scarce environments with limited clinical information. His innovative approach combines feature/gene selection and transductive_SVM [IEEE_TBME2012], whose prediction accuracy is further improved by integrating with a rough-fuzzy approach, thus making it suitable for accurate disease diagnosis [IEEE_TNB2014]. His group developed a sophisticated computational pipeline that helped in identifying long non-coding RNAs that cause metastasis in ovarian cancer [Nature_Communications_2017]. The therapeutic importance of this result immediately attracted media attention (Science-Daily/Medical-Xpress). He recently conducted novel in-silico docking studies that led to the discovery of five plant compounds that destabilize binding of the novel SARS-CoV2 spike protein to its receptor ACE2 in humans. This raises the prospect of using these natural compounds as potential drugs for Covid-19 [Scientific Reports_2020].Other significant contributions include evolutionary clustering with increased convergence [PR2000], differential evolution-based automatic clustering [IEEE_TGRS2010] and SVM- based multi-objective clustering [IEEE_TGRS2009]. These are widely used in image analysis, portfolio management, e-commerce, intrusion detection, and text summarization. The cluster validity proposed by him [IEEE_TPAMI2002] has been used extensively including in CANARY Software (US Environmental Protection Agency) for determining water quality in presence of contaminants.

The nominee has made key contributions in different areas of thermal science. He is one of the first in India and among the few globally to apply dynamical systems approach to characterize combustion instability, which is a globally emerging area of research. He also developed a number of novel strategies for early detection of lean blowout in gas turbine combustors that are simple enough for implementation in real time and at the same time robust enough to work for a wide range of air-fuel ratios that leads to lower emission for both land-based gas turbines and safer operation of aeroengines. He made fundamental contributions in the explaining the role of flow non-uniformities and flame distortions on flame characteristics like burning velocity, vital for understanding turbulent combustion in practical devices. The nominee developed the first completely predictive model for spray formation in gas turbine injectors, capable of predicting spray characteristics based on injector geometry and flow conditions. It is of key relevance to GTRE‘s present and future missions. He was a key investigator in the development of molten fuel-coolant interaction code, PINAK, in collaboration with BARC, the first such code developed in India and is indispensable for safety analysis of nuclear reactors.

Member of the NASI: Yes (YON 2019, Engineering Sciences including Engineering Technology)

Professor Raichur has made seminal contributions in novel drug delivery systems with unique properties over the past 15years.Some of the significant contributions include: Development of nano-sized biodegradable drug delivery system capable of targeting Salmonella infection effectively thereby reducing the antibiotic dosage by 66%, doubling the circulationtime in mice model sand increased bio availability.Graphene oxide and polymer-based capsules for targeting cancerous tumors and releasing of encapsulated cargo by laser triggering thereby supplying drug to the specific site reducing wastage and side effects.Development of bioresponsive (enzyme triggered) capsule system that release drugs under pathological conditions where certain enzymes are overexpressed. These have a tremendous potential for treating cancer and for delivering drugs on demand.Layer-by-Layer assembled nanostructured coatings on probiotic bacteria and yeasts such that the organisms can survive the acidic environment in the stomach and reach the intestine and multiply quickly. The increase in survivability will decrease the number of doses administered to the patient and the time taken tore cover.Designing novel mesoporous nano-silica particles coated with lipids and polymers as stimuli responsive drug delivery systems for treating cancer and typhoid. The lipid coating acts as a capping agent to hold the drug within the mesoporous silica and allows minimum leakage of drug in the stomach before delivery to the intestine.To summarize, Professor Raichur has utilized his expertise in basic surface and colloid chemistry to engineer novel structures and solutions that have implications in biomedical and environmental engineering.

RAVIPUDI, VENKATA RAO (b 1967), Professor (HAG); S. V. National Institute of Technology, Surat.

Member of the NASI: No (YON 2019, Engineering Sciences including Engineering Technology)

The nominee‘s area of research is ―Advanced Engineering Optimization Techniques‖. He has to his credit five innovative and novel advanced optimization algorithms named as (i). Teaching-Learning-Based Optimization (TLBO) algorithm (developed in 2011), (ii). Jaya Algorithm(developed in 2016) and (iii) three Rao algorithms (developed in 2020). These algorithms were developed by him and his research scholars.The main limitation of the existing advanced optimization algorithms is that different algorithm-specific parameters are to be tuned for proper working of the algorithms. Improper tuning may lead to local optimum or inferior solution. Therefore, the nominee and his research scholars had developed TLBO, Jaya and Rao algorithms which are free from the algorithm-specific parameters and hence the user‘s burden is reduced. These algorithms can be efficiently used for optimization of various types of systems, products and processes.The TLBO and Jaya algorithms have proved their effectiveness and superiority over the other competing optimization algorithms. These algorithms have gained wide acceptance by the optimization community in different engineering and science disciplines. More than 10000 research papers have been published so far.The nominee had authored more than 370 research papers published in international journals and conference proceedings out of which about 150 papers were published in SCI and Scopus indexed journals.

SINGH, HARPREET (b 1971), Professor and Dean (ICSR), Indian Institute of Technology Ropar

Member of the NASI: No (YON 2019, Engineering Sciences including Engineering Technology)

Prof. Singh has been consistently contributing to surface engineering and manufacturing domains. His group has developed several commercially viable surface coating systems for power plant boilers and hydro turbines and published several papers along with two granted patents. His group was pioneer in developing cold spray coatings for boilers across the globe. He has also contributed to analytical modelling of erosion and gave a novel parameter, called ―Erosion Mechanism Identifier‖ which can be used to predict the erosion modes of newer materials without doing erosion testing. Recently his group completed the work on the development of a near-perfect optical absorber using carbon nanotubes in UV-Vis-NIR wavelength range, which is an important work considering the inclination of world to non-conventional energy sources, e.g., solar energy, and defense application, e.g., radar blocking. He made another significant contribution to the basic understanding of adhesion mechanisms for the cold sprayed coatings and developed thick-copper coatings for the TOKAMAK application (Invited project by IPR, Ahmedabad). A recent breakthrough is the development of novel and economical technology for surface coatings, named as a grind-coating process, which is now successfully patented in US, while Indian patent is in process. The proposed sustainable technology can be used to deposit a metal coating on metal surfaces and ceramics/glass. He has also established a National facility on Cold Spray this year, which is one of its kinds, and has the capabilities of additive manufacturing. He has been doing several consultancy projects with industry in surface engineering and additive manufacturing. Proposer: Prof. S. K. Das, Seconder: Prof. Javed N. Agrewala Ten Best Publications: 1.

Prof. Bandyopadhyay, FNAE and Praj Industries Chair Professor, is internationally well-known as a leading researcher on Pinch Analysis (thermodynamic methodology to conserve energy). He pioneered in extending the scope of Pinch Analysis to conserve precious resources with application domain spanning from process industries to urban developments. He introduced mathematical rigor and effectively translated that rigor into appropriate physical insights for resource conservation (e.g., energy, water, hydrogen, raw materials, cooling water, etc.). He initiated many novel research areas like simultaneous optimization of resources and waste generation, financial Pinch Analysis, multi- objectives Pinch Analysis, power Pinch Analysis, stochastic pinch analysis, interval Pinch Analysis to account for epistemic uncertainties, dynamic energy analysis, healthcare service sector planning, urban redevelopment to minimize fire-susceptibility, etc. Prof. Bandyopadhyay established the applicability of Pinch Analysis to design of isolated energy systems and developed methodologies for the optimum design of various renewable energy systems (e.g., solar thermal systems, photovoltaic-battery systems, wind-battery systems, etc.) through a novel concept of design space, incorporating various practical constraints and inherent uncertainties of the renewable sources. He was involved in conceptualizing, designing, engineering, construction, commissioning, and operating a grid-connected 1 MWe solar thermal power plant (only plant in the world to integrate of two types of solar collector fields). He solely guided the development of India‘s first Solar Thermal Simulator that is currently being used in industries and in academia. He is co-Editors-in-Chief for ‗Process Integration and Optimization for Sustainability‘ and Associate Editor for ‗Journal of Cleaner Production,‘ ‗Clean Technologies and Environmental Policy,‘ and others.

Prof. Bhat‘s work on interface engineering for contacts and gate dielectrics for highly scaled nanoscale transistors on Si, Ge and 2D semiconductors has provided new insights in realizing future nanoelectronics technology. In particular, his work on sulfur treatment for Ni contacts in conjunction with e-beam evaporated HfO2 dielectric has paved the way for a completely new, ultralow power transistor architecture. His proposal on the tunable schottky contacts as switching elements has enabled the breaking of Boltzmann limit, to realize the best steep slope transistors reported in the literature.Prof. Bhat‘s research on electrochemical biosensors, has resulted in a handheld mobile-lab platform ―anuPath‖ for the point-of-care testing of multiple blood and urine markers for the early diagnosis and management of diabetes and complications, anemia and malnutrition, kidney and liver disease. His work has consciously focused on developing novel receptors, departing from the conventional enzymatic and antibody based assays. Inspired by the physiology of biomolecules, Prof. Bhat developed an optimized chemistry of robust receptors such as metal ions and chemical ligand for example CuCl2, FeCl3, pyridine and imidazole.Prof. Bhat has made substantial contributions on nanostructured metal oxide and 2D materials gas sensors. He has demonstrated single chip gas sensor array for detecting environmental pollutants (CO, CO2, SO2 and NO2). This technology is being commercialized now. He has proposed several novel techniques, such as ZnO honeycombs with polysterene beads, suspended core-shell structure, and 2D-1D hybrids for pushing gas sensors in the range of ppb level, with micro-watt power.

Prof. Chakrabarti‘s work on quantum dot infrared photodetectors (QDIPs) have led to some key breakthroughs such as demonstration of (i) state-of-art characteristics in quaternary-capped QDIPs [130]; (ii) ultra-narrow line- widths in multicolour, broadband, quaternary-capped InAs/GaAs QDIPs [117]. (iii).ex-situ ion implantation in QDIPs drastically enhances their detectivity, [111]; (iv) strain-coupling to enhance the performance characteristics in QDIPs [88]; (v) coupling of heterogenous quantum dot families for enhanced NIR absorption in solar cells [42,43], and (v) of enhancement in optical and spectral characteristics of InAs QDs by Au-Ge plasmonics nanoparticles [81]. The indigenous development of QDIPs with excellent performance has led to the development of India‘s first GaAs-based thermal imagers, responding at long wavelengths (> 8 μm). Prof. Chakrabarti has pioneered the development of prototypes of the 320x256 QDIP focal plane arrays[40] .Further his demonstration of very stable p-type doping of ZnO [1,8,16,65,85] and ZnMgO [64] via PIII needs special mention. This research culminated in the demonstration of homojunction UV LED [63]. A highly sensitive ZnMgO based humidity sensor was also demonstrated [14]. In recent years, his group have done the first principle study to investigate the structural, photophysical, and electronic properties of two-dimensional materials and inorganic perovskite nanomaterials [7,10,13,16]. The objective of this work is to apply the knowledge of density functional theory (DFT) on various interesting materials for their novel application in optoelectronics, spintronics, and spin-caloritronics. He has published more than 400 papers in peer-reviewed international journals and conferences and have graduated 17 PhD students. *References are from the list of journal publications.

Prof.Bhuvaneswari‘s major contributions are: (i) Development of improved power quality converters for variable frequency drives and switched mode power supplies (ii) Design and development of a new shunt active power filtering algorithm that is effective even under distorted and unbalanced supply voltage conditions (iii) Use of these two novelties in small scale hydro-power generation using a three-phase self-excited induction generator for single-phase electricity generation for rural-electrification. (iv) Development of a hybrid microgrid consisting of solar PV, SynRG based wind and battery energy storage to improve reliability and efficacy (v) Development of bidirectional DC-DC converters (BDCs) for battery charging/discharging applications for EV and DC microgrid.Her pioneering work on improved power quality converters and BDCs will directly impact the power consumption in Telecom towers. There are over 300,000 mobile towers in India paying an electricity bill of Rs.50 million per month for charging the batteries. Her research findings impact the energy conservation and power quality of these telecom tower chargers appreciably.When the three-phase machine delivers single-phase power to far-flung areas, rotor over-heating occurs due to imbalances in the currents. These are eliminated by making use of the active filtering technique proposed by her. She worked hard as the associate editor of IE(I) journal to improve its quality and standing. She is the AE of the Transactions of the INAE, IEEE JESTPE and IEEE JESTIE. She is an elected Fellow of IEEE-USA, IET-UK, IETE and the recipient of IEEE Wanda Reder Pioneer in Power Award (2018) and Bimal Bose Award (2011).

Dr. Shivkumar Kalyanaraman (―Shiv‖) has made deep inter-disciplinary contributions to traffic management in wired/wireless networks and in smarter energy/transportation systems:Shiv pioneered explicit rate-based congestion control, notably the ERICA algorithm, which is part of the Asynchronous Transfer Mode (ATM) Forum Traffic Management v 4.0, 1996 international standard and influenced several industrial products. Subsequently robust explicit rate controllers were designed using control theory (2002) and adapted for the Internet context (2005) with reduced information (2-bit) feedback.Shiv specialized the capacity bound for directional wireless communications (2003) which has guided designs of generations of wireless networks. His papers on TCP performance modeling, incorporating error coding, multi-paths in protocol design (2003,2008) and Weak State Routing (2010) using probabilistic state enabled scalability in mobile and wireless networks. His work on Virtual Base Station Pooling (2011) enabled the consolidation of base station (data andcontrolplanes) with cloud edge platforms.Shiv‘s nplug paper (2012), Phase identification (2011), Vehicular Traffic Estimation with Acoustics (2012) applied ideas from networking in smart grids & transportation. "nplug" manage appliance-level demand with a ―grid sense multiple access (GSMA)‖ decentralized algorithm. Phase identification uses network tomography to localize local grid characteristics from remote measurements. Acoustic traffic estimation is a low-cost building block to locally sense traffic conditions.Shiv has 9795+ citations, h-index of 50, 35+ issued patents with many commercialized.

NARAYANAN, GOPALARATNAM (b 1971), Professor, Indian Institute of Science, Bangalore

Member of the NASI: No (YON 2017, Engineering Sciences including Engineering Technology)

Prof. Narayanan has made outstanding and original contributions to space vector-based pulse width modulation (PWM) of power electronic converters in the field of electrical engineering. His work has established that space vector based PWM is more general than the traditional triangle-comparison based PWM. He has introduced a new class of PWM methods termed as ―advanced bus-clamping PWM‖ techniques for voltage source converters. The novel PWM techniques improve the performance of power converters and motor drives in terms of waveform quality, steadiness of torque, reduced acoustic noise and vibration, and improved efficiency. It is noteworthy that the performance is improved only with a modest increase in control software, and without any additional hardware. Overall, Narayanan has made contributions to PWM, induction motor drives, multilevel converters, high-power converters and high-speed electric machines. Excellent experimental facilities have been established for power electronics research including high-power converters and high-speed motor drives. He has successfully guided 7 PhD students and 46 Masters students. He has led technology development efforts in GaN power devices, SiC power converters and high-speed reluctance machines. He is active in executing funded projects and consultancy to industry. His contributions to curriculum development include new courses, hands-on exercises and video lectures. Narayanan‘s academic contributions have been recognized through a number of awards including the INSA Young Scientist Award, Microsoft Research (India) Outstanding Young Faculty Award, IETE Bimal Bose Award, the Karnataka State Prof. Satish Dhawan Young Engineer Award, the Madan Mohan Malviya Prize, and the Jay Jayant Award for Teaching Excellence.

Dr. Nayak has made seminal contributions to key aspects of Indian nuclear programme. He has conceptualized design of an innovative nuclear reactor ―Passive Safe Integral Reactor‖; these are small (100 MWe), modular integral design housing nuclear steam supply systems including reactor core and pumps inside the vessel as a single product. The product is transported to site for direct installation; hence requires significantly lesser construction period and ease in multiplication. He has designed these reactors with several passive systems for safety enabled by indefinitely cooling by air. His analyses show that it is impossible for core melt down to occur and Fukushima type accidents are eliminated by design; thus these reactors can be located close to population like any other industry. He has evaluated sites of retired coal plants for replacement with these reactors considering the site requirements and seismic criteria of existing coal plants. His assessment shows that the base load of ~ 200 GWe can be generated by these reactors by replacing retired coal plants by 2050.He played key role in AHWR design with ‗First-of-a-kind‘ passive-safety-systems, built many world-class pilot facilities to establish AHWR design and safety margins, and a novel methodology ―APSRA‖ for reliability assessment, designed core catcher of AHWR and validated by highly challenging experiments. He conducted several experiments with prototypic corium for PHWRs and demonstrated their resilience against severe accidents,this solve done of critical licensing issues of PHWRs.Published a book ―Severe Accidents in Nuclear Reactors‖(Elsevier), In-press, 300 pages.

Member of the NASI: No (YON 2017, Engineering Sciences including Engineering Technology)

Sujith pioneered the application of nonlinear dynamics and complex systems theory to thermoacoustics. Sujith discovered the route to chaos in thermoacoustic instability in laminar combustors. He then showed that the stable operation of a turbulent combustor corresponds to a chaotic state, and it transitions via intermittency to limit cycle oscillations. He discovered scaling relationships that characterize the universal scaling behavior during self- organization of turbulent flows leading to oscillatory instability. He showed that the combustion noise that occurs during stable operation has a multifractal nature, which is lost at the onset of instability. He showed that combustion noise can be topologically represented as a scale-free network which transitions to a regular network at the onset of instability. These paradigm shifts helped Sujith develop precursors for the onset of oscillatory instabilities, for the energy and aerospace industry.He showed that the emergence of order from disorder happens through a chimera state wherein regions or order and disorder coexist. Using complex networks, he identified critical regions in the flow field, which are optimal locations to implement passive smart control strategies. Sujith demonstrated the quenching of thermoacoustic oscillations using amplitude death.For the stability analysis of rocket engines, Sujith indigenously developed software that is used by ISRO, for its national programmes including GSLV Mk 3 and Chandrayan lander. Such software is not available from foreign sources because of technology control regimes on critical technologies. In summary Sujith made fundamental discoveries from which he developed translational technologies used by the space, aviation and energy industries.

Govindarajan Ramaswamy has made several impactful contributions to high performance computing, computer architecture,andcompilers,which are of direct industry relevance.Govindarajan pioneered the optimal resource- constrained software-pipelining as an efficient integer linear program formulation. His work was also the first to software pipeline an arbitrary loop in a loop-nest, a long-standing unresolved problem, using elegant mathematical techniques. His contributions on developing efficient compilation techniques, runtime systems, and concurrency models have enabled automatic execution of existing (implicit) parallel programs on heterogeneous CPU+GPU architectures, improving performance, portability and productivity in programming heterogeneous HPC systems. His seminal work on GPU concurrency, which was the first to quantify the inhibitors in CUDA Streams, promoted executing multiple applications concurrently. His group proposed several innovative cache designs for multicore architectures, and also developed the first comprehensive analytical model for predicting memory system performance, which won the prestigious ACM India Doctoral Dissertation Honorable Mention Award. Govindarajan has contributed significantly to the National Supercomputing Mission, right from drafting the vision document to playing a lead role in the implementation and chairing the R&D Expert Group. Govindarajan has 138 publications with 3250 citations and a h-index of 30. His work has received international recognition in the form of three best paper awards, five journal editorial board memberships, and 25+ PC membership in top-tier conferences. He has received the fellowship of the Indian National Academy of Engineering, the prestigious Satish Dhawan Young Engineers Award from the Karnataka Government, and the Rustom Choksi award for excellence in engineering research in IISc.

In this work we develop a systematic approach to compile loop nests into concurrent, dynamically constructed graphs of dependent tasks. This is achieved through an effective heuristic that selects the most profitable parallelization idiom for every dependence type and communication pattern. The proposed approach, implemented in an open-source compiler, avoids runtime overheads and performs significantly better than data-parallel executions. (if=1.87, ci=30) 2. G.D. Nagendra, M.

Prof. Vinod Sharma has contributed significantly in wireless communications, networking, information theory and signal processing, as summarized below. Wireless Communication: The first mathematical models and optimal algorithms for energy harvesting communication systems were obtained in [J11] for a point-to-point system, in [C82] for multiple access channels and in [C70] for multihop sensor networks. These are basic building blocks in this very active area. Paper [J16] showed, for the first time, exponential diversity in a wireless system with a single antenna. End-to-end QoS in multihop wireless networks was first obtained in [C105]. Networking: New closed-form expressions for throughput for the currently most used TCP- Cubic and TCP- compound protocols in Internet is provided in [J3, C30]. The first study to provide the throughput of a mix of these protocols in a general network with wireless links is [J2]. Vinod has contributed significantly on stability, rates of convergence and limit theorems, including solving long standing problems in obtaining tight capacity bounds for MACs with fading and capture [J26], discrete time queueing networks with stationary inputs [J38] and stability of polling systems with renewal arrivals [J37]. Information Theory: He developed the first capacity formulae for energy harvesting communication systems [J7]. He also obtained the first algorithm to get tight bounds on capacity of finite state channels [C126]. Signal Processing: New distributed, efficient algorithms were developed and theoretically analyzed for spectrum sensing in [J10], [J6]. Performance and tracking of several blind equalization algorithms was rigorously analyzed in [J20], [C92] solving important practical open problems. Proposer: Prof. P.S. Sastry, Seconder: Prof. Y.

Starting in 1998, Prof. Nishith Verma initiated a research program in the Department of Chemical Engineering at IIT Kanpur on developing technologies for environmental remediation. Prof. Verma subsequently undertook many studies to demonstrate adsorption to be an effective and energy-efficient method for contamination control in air and water [S.No 12: 1-10]. Prof. Verma‘s research laboratory patented two types of novel materials: (1) a multi-scale web of carbon micro-nanofibers and (2) carbon micro-beads, each in situ doped with metal nanoparticles. The catalytic web was grown on carbon fibers as the substrate. The method obviated the need for post-synthesis step and directly provided a robust platform for adsorption and catalytic reactions. These materials were successfully applied for the first time as air filters to remove NOx, SO2, and volatile organic compounds. Carbon beads in-situ doped with Fe and Al nanoparticles during polymerization showed significant adsorption capacity for arsenic and fluoride that has been measured at alarming concentration levels in several regions in India. The materials doped with Ag/Cu nanoparticles were shown to be effective as anti-bacterial agents. Prof Verma's research laboratory has played a pioneering role in the country to successfully integrate nanosciences with the development of novel materials as efficient and cost- effective adsorbents and catalysts in combating an array of contaminants in air and water. Funded by several sponsored and consultancy projects, Prof. Verma‘s initiatives continue to develop nanotechnology-based products and processes for the environmental as well as energy and health applications including electrodes of microbial fuel cells and electrochemical sensors.

In his 24-year long career, Sukanta Bose has made seminal contributions to gravitational- wave (GW) physics and astrophysics, as well as to the LIGO-India mega-science project as follows: (a) Sukanta contributed from the front in building a community of over 100 scientists in GW astronomy in India since 2013; (b) His pioneering works (not limited to Pai et al. Phys. Rev. D (2001)) on how a network of multiple GW detectors can be used coherently to observe the never-before-seen signals supported the case for LIGO-India as well as European and Japanese detectors; (c) He showed how these signals can be exploited to learn about the universe in unprecedented ways. How the measurement of black hole masses can be improved (Ajith and Bose Phys. Rev. D (2009)) eventually established that stellar-mass black holes in the universe can be significantly more massive than those observed in our Galaxy. His works on neutron stars (Bose et al. Phys. Rev. Letters (2018), Forbes et al. Phys. Rev. D (2019), etc.) and cosmology (Nair et al Phys. Rev. D (2018), etc.) helped understand the nature of nuclear interactions and measure the rate of expansion of the universe, respectively. Additionally, Bose was a LIGO reviewer for multiple highly cited LIGO-Virgo analyses and publications, in particular the path-breaking first observation of a binary neutron-star merger. In a multidisciplinary project like LIGO, a relative few are chosen as analysts and reviewers. His roles reflect both his high place in the collaboration and his contribution to these landmark papers. Proposer: Prof. Tarun Souradeep, Seconder: Prof.Sanjeev Dhurandhar Ten Best Publications: 1.

C.S. Stalin has made significant and consistent contributions to the important field of quasar astronomy over the past two decades. His leading contributions include (a) the first detection of intra-night optical flux variations in radio-quiet quasars, providing evidence for the presence of relativistic jets in them (b) demonstrating that the gamma- ray emitting narrow line Seyfert 1(NLSy1) galaxies newly discovered by the Fermi gamma-ray space telescope are the low black hole mass counterparts to flat-spectrum radio quasars and (c) showing that NLSy1 galaxies have black holes masses similar to broadline Sey ferts.Equally noteworthy are his contributions to the Indian astronomical community. From micro-thermal measurements of seeing at Devasthal, he proposed in 1999, that a seeing of ~0.6 arcsec is achievable if the telescope is located at a height of ~16 m above the ground. This prediction has now been confirmed as the Devasthal optical telescope is able to resolve binary stars separated by 0.4 arcsec. He has played major roles in the ground and in-flight calibration of the Ultraviolet imaging telescope(UVIT) on board India's first multi-wavelength astronomical satellite, AstroSat. As the deputy project manager of UVIT and the head of the UVIT payload operations center, he continues to contribute to UVIT and also in the to-be-launched XPoSat. He has guided several PhD students and postdoctoral fellows who have gone on to do well themselves.Thus his outstanding scientific research in the field of quasars and contribution to the community makes Stalin an exceptional candidate for the fellowship of NASI.

Member of the NASI: No (YON 2021, Physical Sciences)

G. Ravindra Kumar has placed India firmly on the global scientific map in the area of high energy density science and study of extreme states. With exceptional scientific vision and leadership, he has done this in an area dominated by leading national labs in the US, Europe, Japan and China. His research has focused on creating, probing and manipulating the behavior of extremely hot, dense plasmas using high peak power, femtosecond laser pulses.Extreme states are not only fundamental but have overlap with and implications for a broad range of scientific disciplines from plasma physics to accelerator physics and from biology to astrophysics. Some of the major breakthroughs he has made are (1) Demonstration of turbulent giant magnetic fields in intense laser produced dense plasmas, acknowledged as a simulation astrophysical magnetic turbulence in the laboratory, (2) Providing ‗super-filamentary‘ transport of mega-ampere currents of MeV electrons in carbon nanotube arrays, crucial for investigating the efficacy of ‗fast ignition‘ of laser fusion, (3) Unraveling ultrafast dynamics of the ‗critical density surface‘ in a laser produced, inhomogeneous plasma and the discovery of terahertz acoustics in laser plasmas, resolving two dimensional spatial motion on micrometer scales, simultaneously with femtosecond time resolution, a major leap in understanding plasma instabilities and heat transport and (4) Devising novel ways to monitor transport of relativistic electrons ‘in situ’ in solids via Cherenkov emission. Measured the lifetime of these electrons and showed them to be extraordinarily long - information crucial for novel radiation sources and laser fusion.

CP violation in the Standard model (SM) described by the Cabibbo-Kobayashi- Maskawa (CKM) mechanism, for which Kobayashi and Maskawa awarded Physics Nobel Prise (2008), CKM phenomenon implies at least 3 generations of quarks (all discovered by 1995) and a complex phase, known as CKM phase, which gives rise to CP violation in SM.The method proposed by Giri-Grossman-Soffer-Zupan (GGSZ) PRD 68 (2003) 054018 used first time PRD 70 (2004) 072003 to determine CKM angle gamma (phi-3) both in Belle (KEK) and BaBaR (SLAC) experiments. To date, GGSZ (also known as Dalitz) method is dominant method, and continue to be the model independent method for CKM angle gamma in Belle-II (KEK) and LHCb (CERN) experiments. Work on B decays JHEP 11 (2004) 084, new Z boson EPJC 45 (2006)151 and Lepton Flavour Universality violation PRD 88 (2013)114023 are compelling new-physics search a venues.Precision B and Neutrino experiments are most promising pathways to the future directions. Recent measurements of R(K) and Lepton Flavour violation in B decays JHEP 03 (2021) 105 by his group, and precision neutrino observations PRL 118 (2017) 231801, PRL 123 (2019) 151803 will be key to New-Physics.

The research activity of DK‘s group broadly focuses on understanding the photophysics, electronic properties and device physics of 1.Molecular semiconductors (MSs) and 2.Halide perovskite (HPer) materials.Molecular Semiconductors: DK‘s group focused on triplet exciton studies. The triplet states in the fluorescent organic semiconductor usually limits the efficiency of organic light emitting diodes (OLEDs). His group has made a considerable progress in explaining the triplet kinetics, where Solved the mystery of enhanced TTA at room temperature via thermally assisted TTA mechanism dominance over monomolecular triplet decay rate with customized advanced spectroscopic studies.His group‘s spectroscopic finding on operational bipolar and unipolar devices could explain some of puzzling results in MSs community where it is pretty unusual to make 1200 nm thick active layer diodes to get highly efficient EL devices.Halide Perovskites: In addition to exploring device physics of LEDs and solar cells, there is contributions in the understanding of the physics governing electronic properties, transport, defects and luminescence in HPer systems. DK showed that in HPer systems there is an interplay between dynamic vs static disorder, which influences transport, piezoelectric and optical properties. This viewpoint is now widely accepted in the community. He has been invited to submit multiple invited review articles based on device and fundamental work for this class of photonic materials.

Prof. Debasish Majumdar's research covers a wide spectrum of astroparticle physics that include dark matter, dark energy and cosmology, primordial gravitational waves and neutrino as well as nuclear processes in late stages of a star. The nominee's contribution in the field of particle dark matter phenomenology and its direct and indirect detection are commendable. The nominee not only had proposed and explored viable particle dark matter models by extending Standard Model of particle physics but investigated their impacts on direct dark matter search experiments and possible indirect signatures of dark matter in the cosmos. The nominee worked out in detail easily computable analytical expressions for the diurnal and yearly variations of dark matter direct detection signals. The nominee also made very significant contribution in predicting the dark matter mass whose indirect synchrotron signal could be detected by the upcoming Square Kilometer Array (SKA) Telescope. The dark matter induced first order phase transitions and the consequent gravitational wave production were thoroughly worked out. Possibility of IceCube neutrinos in PeV energy range to have originated from heavy primordial dark matter decay was successfully addressed by the nominee whereby the mass and lifetime of such dark matter and simultaneously the Universe's matter-antimatter asymmetry was explained. The accelerator neutrino were obtained oscillations for addressing possible violation of equivalence principle. Extensive simulations for the Iron Calorimeter (ICAL) detector at the proposed India-based Neutrino Observatory (INO) and physics issues constitute valuable chapters in INO reports. The work on cosmological perturbations and dark energy were also commendable. Proposer: Prof. Sukalyan Chattopadhyay, Seconder: Prof. Munshi Golam Mostafa Ten Best Publications: 1.

Member of the NASI: No (YON 2021, Physical Sciences)

Dr. Malik, with his students, has devoted the last two decades to research on various aspects of the BRST formalism. His notable contributions are (i) the concept of dual BRST symmetries [17, 21, 23, 24, 58, 76]*, (ii) a set of field- theoretic models of Hodge theory [18-20, 54, 59, 87, 113], (iii) the augmented version of superfield approach (AVSA) to BRST [25-27, 48-51, 85], (iv) the anti-chiral superfield approach (ACSA) [103, 107-112], (v) the BRST approach to higherp-form (p=2,3) gauge theories [56,59,60,87].These have led to (i) the proof of 2D (non-)Abelian gauge theories as a field theoretic example of Hodge theory and to a new kind of topological field theory (TFT) which captures [24] a few key features of Witten-type TFT and Schwarz- type TFT, and (ii) the derivation of (anti-)BRST symmetries for the matter fields together with the gauge and (anti-)ghost fields in an interacting gauge theory (within the framework of AVSA/ACSA [46-49,52]).In addition to the above works, he has contributed significantly in the realm of quantum groups [9, 38] and their applications to the physical systems [11, 14, 16], conformal field theories on the higher-genus Riemann surfaces [4-7], (supersymmetric) W-algebras [11, 12, 15] and corresponding integrable models, anomalous gauge theories [3, 64] and proof of the N = 2 SUSY quantum mechanical models as the examples of Hodge theory [86,89,91,94,100].References are from his full list of publications.

Prof. Bhabani Prasad Mandal has made significant contributions in theoretical research as well as teaching and science education. His invention of Finite Field BRST (FFBRST) transformation facilitates to solve many long-standing problems in QFT e.g finding correct prescriptions for the poles in the axial gauge propagator, regularizing the energy integral in the Coulomb gauge, removal of Gribov ambiguity, mapping nonperturbative QCD to perturbative QCD, avoiding the conformal anomaly in the Polyakovbosonic string theory. This earned wide appreciation in gauge field theories for enormous applicability. He has made a breakthrough in the field of nonhermitian quantum theories by being the first to realize the PT symmetry breaking in complex QES systems. This work has more than 200 citations. Prof. Mandal is working voluntarily for many years to ensure equal opportunity in STEM education for VIS. He approached the national science academies and won their support in this regard. He organized a one day awareness camp at BHU (Partially supported by NASI) to motivate the educators and the VIS.

Standard Model of Particle Physics is immensely successful but failed miserably to explain several long-standing issues. Amongst them, the Neutrino mass and mixing, Dark matter, and the Flavour anomalies are the prominent ones, which necessitate profound scrutiny. Prof. Rukmani Mohanta‘s research pursuit encompasses those riddles to examine simultaneous explanation and in deciphering the signals of beyond the Standard Model (BSM) Physics. Leptoquarks (both vector and scalar) as viable scenario of BSM invoked by her group to explain the observed Lepton Flavor Universality (LFU) violating observables R(K)/R(K*) in semileptonic (b-to-s) transition and R(D)/R(D*) in b-to-c tree-level transition. They have shown that all the flavor anomalies can be successfully elucidated with leptoquarks, which appears now as one of the most promising BSM scenarios [4,7].Dark matter, which constitutes almost one- fourth of the total energy budget of the Universe, has attracted significant attention resulting overwhelming theoretical and experimental studies. Rukmani‘s group employed BSM scenarios, like Lmu-Ltau model to describe the dark matter relic-density, neutrino mass and LFU-violating observables R(K)/R(K*) in a single-platform and a new B-L model as a scenario of Majorona Dark matter [8,9].Other interesting scenarios of Lepton flavor violation in long-baseline neutrino experiments and B-meson decays are illustrated in [5,6]. Possibility of nonuniversal Z-prime boson for understanding B->Kpi puzzle and the existing flavor anomalies pointing towards the tantalizing possibility of fourth-generation are discussed in [1-3].Unified description of flavor anomalies, radiative neutrino mass and ANITA anomaly along with Collider constraints presented in [10], indicating the possible existence of Leptoquarks.

MUKHERJEE, ASMITA (b. 1971) Professor, Dept. of Physics, IIT Bombay, Mumbai

Member of the NASI: No (YON 2021, Physical Sciences)

The nominee has made major scientific contributions in the field of QCD spin physics. In a series of work she has investigated jet production cross sections in polarized and un polarized proton-proton scattering at next-to-Ieading order in QCD, dependence of jet algorithm, and resummation of large logarithmic contributions [1,2]. Large transverse momentum jet with identified hadron provide a very important tool to probe the fragmentation function [3]. The theory results of [1,2,3] are currently being used by experimental collaborations at the relativistic heavy ion collider (RHIC) at Brookhaven National Lab, and at the Large Hadron Collider at CERN for analysis of the data. Other objects of current interest in this field are the transverse momentum dependent parton distribution and fragmentation functions (TMDs). Unlike collinear parton distributions, these are process dependent, due to the presence of gauge links. This makes the applicability of QCD factorization questionable in many of these processes involving TMDs. The candidate has addressed key issues related to the universality of the quark and gluon TMDs [4,5,6]. She has calculated the TMD Collins fragmentation function in a model and showed that these can explain the data from experiments[7]. On another topic, namely generalized parton distributions, that are probed in exclusive electron• proton collision processes, she has made interesting study in exploring the amplitude of these processes in positon space in a simple model [8]. In a relatively different field of atomic physics, she has made important contributions in obtaining the selection rules for atomic transition in interaction with twisted light, or light that has a spiral wave front [9].

Dr. Kunal Purnachandra Muthe has significant contributions in the field of condensed matter physics viz. functional materials for gas sensors, thermoelectrics, solar cells, superconductors and optically stimulated luminescent (OSL) materials. His simple and cost effective large scale synthesis of carbon doped Al2O3 (OSL) phosphor process garnered an international US patent. He could solve three fundamental issues pertaining to thermoelectric power generators viz. synthesis of high figure-of-merit materials; development of electrical contacts with very low specific contact resistances; and device design with minimum thermal shunt path. Two of his technologies have been successfully commercialized and now available in the market. H2S sensor (10-50 ppm) technology is crucial for Department of Atomic Energy (DAE) as it ensures safe operation of Heavy Water Plants. Table top static gas sensing unit, a niche product helped to achieve the complete indigenization of sensor development technology and fetched presidential award (DST) to one of the licensees. Besides, first products have attracted veterans like CSIR-NPL and SPPU. Import substitute indigenous technology namely titanium hydride targets has been successfully employed in portable neutron generator applications. A novel TIRANGA process using Zn based nanoparticles was established for effluent treatment capable of converting the waste water (2000 L/day) into clean water suitable for irrigation. He has written and directed four Edutainment Skits that clarify myths about nuclear energy and these have been presented to large gatherings (about 10,000) across several research organizations and educational institutes. He published about 120 papers in the refereed journals and 2 patents (USA & Indian). Proposer: Prof. A. K. Tyagi, Seconder: Dr. R. S. Ningthoujam Ten Best Publications: 1. M. Kaur, K. P.

Quantum Information and computation (QIC) is one of the most fascinating fields of research around the world and has the potential of revolutionizing the future of communication and computational technologies. Her work includes multiport quantum communication with and without security as well as their realizations by using quantum optical elements (PRL 93, 210501; PRA 90, 022319 (2014); PRA 92, 052330 (2015); PRA 93, 032338 (2016); PRA 93, 052313 (2016); PRA 98, 052131 (2018); PRA 100, 052304 (2019)), the discovery of a method like density matrix recursion method, which can be applied to quantify quantum correlations in large superposed systems (NJP 15, 013043 (2013); PRL 111, 070501 (2013); PRB 96, 075143 (2017)), effects on quantum correlations in presence decoherence (PRA 91, 062119 (2015); PRA 97, 062324 (2018)), characterization of sharability of quantum correlations in multiparticle systems (PRA 85, 040102(R) (2012); PRA 98, 012310 (2018)), new measures for multisite resources useful for quantum technologies with many-body systems (PRA 81, 012308 (2010); PRB 99, 064422 (2019)).

The work on oxide glasses has been well cited and included in the Handbook of Glass Data published by Elsevier. The work on BiCaSrCuO glasses, superconducting glass ceramics is novel and significant. The exponential decay of critical current density with external applied field on tubular samples of Y-123 superconductor (1989) is an addition to the literature. The work on RF-sputtered Cu-Zn spinel ferrite nano-crystalline magnetic thin films has been cited well and summarized in an invited book chapter by Nova publishers. The thin films of SnO2 show the dependence of optical properties on environment under which these films are deposited. The RF –sputtering technique is successfully used to deposit a new class of multilayer structures called discontinuous multilayer of [SnO2/ Co, Mn]n (n = 5 – 60) to understand the role of interfacial regions on the magnetic and optical properties of these structures. The work on [SnO2/ Cu-Zn ferrite] multilayer has highlighted the effect of interfacial regions on the properties of these systems. He has developed method of preparing magnetic nanoparticles of various shapes and sizes. The XRD powder data on Mn-Zn ferrite nanoparticles has been included in ICDD release 2019. The work on magneto-viscosity of ferrofluids based on nanoparticles of various shapes is important in view of their applications in energy conservation devices. He played a key role in setting up various teaching laboratories and facilities for condensed matter research namely material synthesis (bulk and thin films) and characterization, liquid nitrogen and liquid helium facilities at the university.

Prof. Ajit Srivastava is an unusually versatile physicist. He has made contributions to the theory of topological defects in the early universe, to the theory of the quark-gluon plasma (QGP) in relativistic heavy-ion collision experiments (RHICE), and to astrophysics.In a rare venture for a theorist, he took up experiments on defects in liquid crystals, first in Syracuse, and later in his own lab at IoP for testing cosmic defect theory. His research in this area has the distinction of providing the first confirmations of quantitative predictions of cosmic defect formation theory. His analysis of the power spectrum of flow coefficients in RHICE established an analogy between the evolution of QGP and the growth of fluctuations in inflationary cosmology. He was the first researcher to investigate the effects of the enormous magnetic field (about ten thousand trillion Tesla) in the initial states of RHICE.His recent proposal uses pulsars as remotely stationed Weber gravitational wave (GW) detectors. The waves from a GW event leave their imprint on the shape and hence rotation of neighbouring radio pulsars. This is observable in principle on earth as perturbations on the pulse profile. This opens up the possibility to revisit past GW events such as from supernovae recorded in far past.Prof. Srivastava has been a very successful mentor at the PhD level and is simultaneously an acclaimed science communicator, active in science outreach programs and regularly invited by prominent institutions all around the country to speak to students of diverse ages and backgrounds.

Prof. Rajesh Srivastava is one of world‘s leading Atomic Physics theorists and worked on wide variety of Atomic and Molecular structures and collisional problems by developing quantum mechanical non-relativistic and relativistic theories and extended their applications to the Plasma Physics. He is internationally known for his electron–atom /ion Relativistic Distorted Wave (RDW) theory, and reliable Collisional Radiative Model for Plasma Diagnostics. His group at IITR has conducted research in these areas for nearly four decades, developing new theoretical formulations and sophisticated computer codes that led to new experiments at the fundamental level. His studies involved different charged particles impacting on neutral atoms, ions and molecules in wide variety of manners. He developed Density matrix theory to study alignments and orientation of the excited sates and polarization of their decay. Such studies have only been carried by few groups in USA, Canada, Germany, and Poland, who collaborated with him. He developed RDW theory which described collisions of polarized electrons by any polarized atomic species and explained uniquely the complete electron scattering experiment through generalized Stokes and spin STU parameters. He was invited as an expert member (2010–2013) at IAEA, Vienna, to monitor electron collision data for world‘s biggest ongoing ITER project in France. He was Sole Indian Representative, of General Committee of ICPEAC (1995- 1999). He developed various reliable collisional-radiative models of inert gases, its ions and mixture plasmas using reliable fully relativistic electron impact excitation cross-sections of inert gases and its ions for their diagnostics.

General Relativity (GR) is an extremely successful description of gravitation and cosmology. However, both theory and observations suggest that GR might have significant classical and quantum corrections in the Strong Gravity (SG) regime. SG corrections, described as modified gravity theories, become important where classical solutions result in space-time singularities, notably, in Early Universe cosmology near the Big Bang and the interiors of black-holes. In the last ten years, Shankaranarayanan and his team of postdoctoral fellows and students have focused on uncovering characteristic signatures of the SG corrections, as imprinted on observational features in these two domains as shown below.In a major component of this program, Shankaranarayanan used quantum entanglement and fluid-gravity correspondence to resolve long-standing problems in black-hole physics. Since entropy is a single number, he has shown that, we need other quantities to provide complete information about the black-hole microstates. With doctoral students, he has shown that quantum entanglement mechanics provides a one-to-one correspondence with black-hole thermodynamics. The universality of results suggests quantum entanglement is the fundamental building block of space-time.The spectrum of energy density fluctuations, baryon asymmetry, and coherent large-scale magnetic fields are the three observables that provide crucial information on physics at very high energies. Inflation can only provide a mechanism to explain the density perturbations, and the origin of primordial magnetic fields and baryon asymmetry require physics beyond the standard models of cosmology and particle physics. Shankaranarayanan provided a novel, purely electromagnetic mechanism that generates large-scale fields and leads to baryogenesis with doctoral students.

Prof Tripathi‘s research focuses on the magnetic coupling and dynamics of the solar atmosphere. He has made significant contributions in two specific areas of solar astrophysics, viz. initiation and evolution of solar eruptions at various spatio-temporal scales [1,2,3,8,9] and heating of the solar atmosphere[4,6,7,10].Durgesh has established that magnetic reconnection plays a crucial role in large-scale eruptions such as CMEs, which are often preceded by small- scale dynamics events, that suggests a unified picture of the origin of small- and large-scale dynamic events.Durgesh has also successfully demonstrated that impulsive heating is a viable mechanism for the existence of the solar corona and the formation of the solar wind. More importantly the scenario proposed by Durgesh‘s research [4,7,10] provides a unified picture of various structures in the solar corona, including the magnetic switchbacks, recently discovered from the Parker Solar Probe.Prof Tripathi is a first-class scientist with an outstanding track-record and is well respected in the community. Durgesh has published 75 refereed papers, with 2874 citations and an h-index of 32. He is the most cited solar physicist in the country below the age of 50.Since 2012, Durgesh, as the Principal Investigator, has been leading the efforts in conceptualizing and building the Solar Ultraviolet Imaging Telescope (SUIT) that will fly onboard the Aditya-L1 mission of ISRO in 2022. He is a member of Aditya science working group. He has arranged three international conferences at IUCAA and several workshops at universities to encourage research in solar astrophysics.

VADIVEL, MASILAMANI (b. 1948) Former Professor of Laser Physics, Anna University, Chennai

Member of the NASI: No (YON 2021, Physical Sciences)

I have known Prof V Masilamani over last thirty years as he was a Professor of laser physics in Anna University and we had been working on a very closely related areas: he was on excited state photo physics and we on excited state photo-chemistry. He has done some original work on a new molecular species called Super exciplex produced only under population inversion condition produced by a pulsed high power laser (N2 or VAG). During his tenure in Anna University he was the head of laser Center and over 100 M Tech students and 4 Ph D scholars were trained by him.

Shikha Varma is an experimental condensed-matter physicist working in areas of nanoscience, nano-bio and ion-beam applications. Her research involves studies of quantum-dots, self-assembled nanostructures and nanopatterned surfaces for understanding and modulating properties like electronic, optical, magnetic, wetting etc. for achieving functional platforms. Her studies on nucleation of quantum-dots by MBE present very important studies in this field. Her investigations of self-assembled non-equilibrium patterns induced by ion beams display many significant fundamental and functional aspects. Her group was the first to achieve prominent band gap-tailoring and biocompatibility during ion-induced nano-patterning in TiO2, exhibiting potential for biosensing and reversible-Resistive switching. Her group has shown that hybrid-conjugated nano-biosensors, prepared via novel co-electrodeposition route, exhibit exceptional sensitivity and fast response-time for non-enzymatic glucose sensing. She has shown that effective electronic structure tuning is instrumental in inducing enhanced photocatalytic activity in aligned ZnO nanorods and interesting plasmonic characteristics in graphene quantum-dots. Her group was the first to demonstrate via XPS- STS investigations that DNA can act as a sensor of mercury nano-particles. Continuing her study on bio- adsorption of arsenic pollution in Bengal-delta, in a novel approach a tailored biomimetic platform has been fabricated for the detection and sequestration of arsenite via charge conjugation [140]. She has setup facilities like ion-based nanofabrication in conjunction with XPS, low temperature Raman, AFM-STM-STS and UV-Vis facilities. Many groups (more than 120) from universities and institutes have utilized these facilities resulting in some very good collaborative papers (not included in list of ten given here).

ARVIND (b 1968), Professor, Indian Institute of Science Education and Research, Mohali

Member of the NASI: No (YON 2020, Physical Sciences)

Professor Arvind has made seminal contributions to the areas of Quantum Optics, Foundations of Quantum Mechanics, Quantum Information and Physics Education Research. He approaches Quantum Optics from a group theoretic and phase-space point-of-view. Theory of two mode squeezing, intrinsically two mode notion of antibunching and nonclassicality are some of the highlights. Earlier he developed a connection between Bell's inequalities and quantum optical nonclassicality for Gaussian states which he has recently extended to non-Gaussian states. He was the first to point out the capability of optically passive transformations to produce entanglement. His focus is on exploring weak quantum measurements to extract information and to compare sequential weak measurements, Arthurs-Kelly measurements, homodyne and heterodyne schemes as different ways to estimate quantum states. He has contributed to the theory of geometric phases including for three-level systems and for mixed states. He was one of the first scientists in India to work in the field of Quantum Information and early on explored the role of entanglement in the Deutsch-Jozsa algorithm. He has connected his geometric description of three-level quantum systems with qutrit quantum contextuality which led to its experimental implementation. His recent contributions include extremal extensions of entanglement witnesses, new connections between unextendable product bases and entanglement witnesses, discovering new bound entangled states and using them to enhance quantum key distribution (QKD) rates, and using displaced squeezed states to enhance continuous variable QKD schemes. He has has designed new experimental setups for physics pedagogy which have been introduced in the curriculum at various institutes. Proposer: Prof. N.

Professor Barman has carried out pioneering research on ultrafast spin-dynamics, magnonics and spintronics by developing world-class indigenous laboratories and become a world leader in the above fields. He has made outstanding contributions in the highly debatable ‗ultrafast demagnetization‘ for all-optical manipulation of spin at femtosecond timescale in magnetic thin films, multilayers, Heusler alloys and 2D material/ferromagnet heterostructures to underpin the underlying mechanisms. He has made seminal contributions in ultrafast spin dynamics of single/isolated nanomagnets in deep nanoscale regime and discovered the dominance of edge-localized spin-wave modes in these systems. He has invented novel classes of one-, two- and three-dimensional magnonic crystals with reconfigurable and reprogrammable band structure and designed GHz frequency on-chip communication and processing devices based on those. He has made pioneering contributions in spin-orbitronics by inventing novel all- optical methods to study spin-Hall effect, spin pumping effect and Rashba effect and investigated roles of perpendicular magnetic anisotropy, interfacial Dzyaloshinskii-Moriya interaction, voltage-controlled magnetic anisotropy and spin-orbit torque in controlling ultrafast spin dynamics and switching. He has investigated topological magnetic objects like domain wall, vortex and skyrmion, and developed novel all-magnetic vortex-transistor and logic devices for the first time. He has made probing contribution in the field of straintronics, where he investigated and controlled magneto-elastic modes in strained nanomagnets and developed extreme sub-wavelength magneto-elastic electromagentic antenna. He has made scholarly contributions by authoring several Topical Reviews, Perspectives and the first Monograph on ultrafast spin dynamics. He also led and edited the first Magnonics Roadmap including about 60 experts across the globe. Proposer: Prof. Milan Kumar Sanyal, Seconder: Prof. Samit Kumar Ray Ten Best Publications: 1. S.

CHAKRABARTI, NIKHIL (b 1963), Senior Professor, Saha Institute of Nuclear Physics, Kolkata

Member of the NASI: No (YON 2020, Physical Sciences)

Nikhil has done outstanding research in several areas of plasma physics spanning fusion applications, space physics and fundamental phenomena in laboratory plasmas. With deep physical insight and great mathematical ingenuity he has solved a number of complex nonlinear problems including derivation of the relativistic wave breaking criterion, phase mixing of upper hybrid waves (Physical Review E 86, 016408, 2012) and exact analytic solutions for coherent structures in regular (Physics of Plasmas 18, 102301, 2011) as well as strongly coupled plasmas (Physical Review E 83, 066406, 2011). His work on wave breaking phenomena in non-relativistic (PRL 106, 145003, 2011) and relativistic (PRL 110, 215002, 2013) magnetized plasmas are very noteworthy. In the nonrelativistic problem he was able to obtain exact time-dependent, strongly nonlinear, collapsing magnetosonic wave solutions for compressible MHD plasmas that can have an important application in explaining the seeding mechanism for clumping in the universe prior to star formation. In another remarkable theoretical contribution (Physics of Plasmas 2, 3296, 1995), Nikhil has provided a novel physical mechanism for the saturation of the long scale end of energy cascade in magnetized turbulence through secondary instabilities. This has important implications for energy transfer mechanisms both in laboratory (fusion) plasmas and astrophysical plasmas. Finally, along with his student, Nikhil was instrumental in obtaining the first ever direct experimental observation of electron acoustic waves in a laboratory plasma (Physics of Plasmas 24, 062111 2017) and explaining its physical origin – an outstanding fundamental plasma physics discovery.

He promoted its use in the form of collaborations and educating a large number of users within the country in addition to his own research on the study of magnetic structures and their influence on the physical properties in transition metal based oxides systems. In his several studies on half-doped manganites, he has shown that the complex magnetic structures in these compounds are stable only in a narrow composition range and they are susceptible to perturbations viz., site disorder and external pressure. The site disorder in the compounds induces melting of the charge- ordered state and leads to evolution of the CE-type AFM ordered insulating state to a ferromagnetic metallic state with increase in ionic radii and site disorder. Similarly, from neutron diffraction studies under the influence of external pressure, he has shown that the magnetic structures in these compounds evolve from CE-type AFM state to ferromagnetic state via intermediate structures. Using polarized neutrons, he has shown the presence of magnetic short-range order coexisting with magnetic long-range order, well below the magnetic ordering temperature in half-doped manganites. He has shown the presence of spin phonon coupling and its possible role in driving the spin reorientation behavior in orthorhombic and hexagonal frustrated manganites. Proposer: Dr. S.L.

Dr. Amarendra is a specialist in atomic characterization of materials. He carried out extensive experimental studies on irradiated metals and alloys, which paved way for atomistic understanding of helium clustering in metals and alloys. The most significant contribution had been the indigenous design and development of variable low energy positron beam system in 1995, which is one of the dozen systems existing world-wide. This enabled non-destructive depth profiling of vacancy-defects, which was used extensively for studying thin films and multilayers. His detailed studies brought out the first experimental evidence for the vacancy cluster size distribution in amorphous Si using positron beam and ion channeling techniques. He made fundamental contributions to the understanding of the effect of radiation on nuclear structural materials. The void swelling behavior of D9 steel had been investigated so as to deduce the peak swelling temperature, which very important for fast reactor applications. His studies on metal-slicides provided important insights on the role of defects and diffusion in the formation of metal-silcide phases. Dr. Amarendra is instrumental in setting up of UGC-DAE CSR, Kalpakkam Node with advanced experimental facilities for use by University faculty/students, which is one of the four Centers functioning under UGC-DAE Collaborative mode.

Kanekar has made very significant contributions to our understanding galaxy formation and evolution as well as to measurements of the cosmological variation of fundamental constants. He developed new theoretical techniques to probe the cosmological evolution of fundamental constants using redshifted hydroxyl lines. He discovered two new redshifted ``conjugate'' satellite hydroxyl systems, a special class of hydroxyl absorber- emitter that is well-suited to probe changes in the constants. Using conjugate-hydroxyl lines, ammonia lines, and methanol lines he obtained the most stringent constraints on changes in the fine structure constant and the proton-electron mass ratio, over timescales of 3-8 billion years. He detected the three most distant known 21cm absorbers in normal galaxies, and obtained the first identifications of absorbing galaxies at high redshifts, z ~ 4, via ionized carbon emission, yielding estimates of their molecular masses. He identified the first case of a cold disk galaxy at these redshifts, showing that such massive disks form at early times, in contrast with standard models of galaxy formation. He obtained the first detections of these galaxies in molecular emission, finding extremely large molecular gas masses. He used HI 21c m ``stacking'' to measure the average atomic gas mass of star-forming galaxies during the epoch of galaxy assembly, and showed that the atomic gas is consumed rapidly in such galaxies during this epoch, explaining the observed decline in the star formation activity in galaxies at later times. He discovered a thresholdin the neutral hydrogen column density for the formation of the cold phase. Proposer: Prof.Jayaram Chengalur, Seconder: Prof.Yashwant Gupta Ten Best Publications: 1. A.

Member of the NASI: No (YON 2020, Physical Sciences)

Gunadhor Singh Okram has made significant contributions in the physics and material science of nanoscale thermoelectric materials, oxides and metals covering nanolattice, quantum size effect (QSE), surface plasmon resonance (SPR), thermoelectricity and catalysis. These are possible with his significant in-house development of thermopower and resistivity setups [Rev. Sci. Intsrum. (2008, 2019)] and their dedication to nation as user facilities to study these properties, free of cost, on a large number of samples of several researchers of colleges, universities, national laboratories and institutes of India. In Ni nanoparticles, he demonstrated for the first time (i) self-assembly [J. Mater. Chem. C (2014), Faraday Discussions (2015)], (ii) coexistence of HCP and FCC atomic Ni lattices internally with drastic change in the density of unoccupied electronic states, and QSE [J. Phys. Chem. C (2016)], (iii) QSE- induced exponential drop in heat capacity [Appl. Phys. Lett. (2017)], and (iv) their sensitivity on SPR to dielectric environment showing potential biomedical and SPR sensor applications [PCCP (2017)]. In thermoelectricity, desirable for waste heat harvesting, he revealed for the first time enhanced thermoelectric properties in Cu-doped Bi2S3 nanorods [Nano Research (2016), ACS Appl. Mater. Interfaces (2020)], polyaniline [Appl. Phys. Lett. (2014)], Ag- induced Ag2S [ACS Appl. Energy Mater. (2019)] and Ag-doped CuS [PCCP (2018)]. In catalysis, he established for the first time excellent catalytic properties of silica-coated ZnO nanoparticles in the presence of ultrasound in high-yield multi-component synthesis of biological and medicinal application potential triazolo[1,2-a] indazole-triones at 60 °C [Green Chemistry (2017)].

Prof. Ramakrishna has made significant contributions towards the development of structured composite materials (metamaterials) at optical, infra-red and microwave frequencies. He used insightful theory to understand wave phenomena in complex structured materials and design efficient metamaterials. Several novel contributions such as the use of amplifying media in metamaterials and plasmonic structures, application of transformation optics to negative index materials, design of optical frequency metamaterials, negative refraction in acoustic metamaterials, coherent control of metamaterials by atomic / molecular resonances, anisotropic metamaterial fibers etc. were made by him. His experimental work on absorbing/emissive metamaterials from microwave to optical frequencies on a plethora of substrates ranging from metals, polymers to fabrics has created a path for implementing these in military stealth technologies. His novel work on switchable and nonlinear metamaterial absorbers by imbedding phase change materials like vanadium dioxide and nonlinear materials have opened new possibilities in the field. He has pioneered the use of structured indium tin oxide thin films for developing infra-red and microwave metamaterials that have optical transparency. His work on optical properties of plasmonic nanostructures, their use for surface enhanced Raman scattering (SERS) and the possibility of obtaining broadband extraordinary transmittance in checkerboard plasmonic systems are important. His studies on aged latent fingerprint visualization by thin film depositions and inclusion of fluorescent dyes bring in new insights from optical interference into fingerprint imaging for forensic analysis. After joining CSIR-CSIO he has launched new programs on nanophotonics and diffractive optics for technology development, particularly for display and defence applications.

SAHOO, BIJAYA KUMAR (b 1977), Professor, Physical Research Laboratory, Ahmedabad

Member of the NASI: No (YON 2020, Physical Sciences)

Prof. Sahoo has made seminal contributions to a wide range of problems in modern atomic physics. His developed analytic response relativistic coupled-cluster theory is a path breaking achievement by him, which gave very reliable calculations of isotope shift constants for atoms and combining results from this method with measurement, he probed possible magic behaviour of nuclei around neutron number 32. By studying electric dipole moments (EDMs) of atoms, he obtained the best limits for the chromo-EDMs of the combined up- and down-quarks |푑 푢̃ −푑 푑̃ |<2.7×10−27 e-cm and the chromodynamics parameter |휃 ̅|<1.1×10−10, which are about ten orders larger than the Standard Model predicted values. By studying atomic parity violation in 133Cs atom, he put stringent constraints on the low-energy effective electron-quark coupling gAV = -0.1877(9), isospin conserving oblique parameter S ≃ 0.60(44), and mass of an extra Zx boson MZx > 2.36 TeV with 95% confidence level. His other noteworthy contributions include the best limit on a local Lorentz invariance violating parameter (C0 =2.6x10-18 of an electron, searching several atoms and ions for ultrahigh precision (fractional uncertainty below 10-18) atomic clocks, and offering high-accuracy spectroscopic data for applications in astrophysics to predict interstellar lines and in material sciences to explain interactions of atoms with walls of different material media by carrying out ingenious theoretical analyses. He also carried out a pilot study recently on Quantum Computation. He has collaborated widely internationally and at the highest level. In 2020, he was listed among world‘s top 2% scientists by Stanford University. Proposer: Prof. Ravindra Eknath Amritkar, Seconder: Prof. Ashok Kumar Singhvi Ten Best Publications: 1. Á. Koszorús, W.

Member of the NASI: No (YON 2020, Physical Sciences)

Subramanian has significantly contributed to diverse areas of astrophysics. His impactful work on cosmic magnetism, emphasizing the crucial role of magnetic helicity conservation for mean-field dynamo saturation, led to a paradigm shift in the field. He proposed the first consistent definition of magnetic helicity density, as the density of correlated links, derived its local conservation (ApJ , 648, L71), and constructed detailed models to explain galactic fields (A&A, 448, L33; MNRAS, 428, 3569) . Subramanian showed that large-scale field generation is intriguingly like 'tunneling' of small- scale correlations, in helical turbulence (PRL, 83, 2957). His work on fluctuation dynamo saturation is critical to understanding galaxy cluster magnetism (MNRAS, 366, 1437). Subramanian proposed a novel thermal battery for seed field generation during reionization (MNRAS, 271, L15). His review on Astrophysical magnetism is a standard reference in the field with high impact (Phys. Rep., 417, 1). Subramanian is a leading expert on primordial magnetism (ROPP, 79, 076901), having predicted its distinctive signatures on Cosmic Microwave Background anisotropy (PRL, 81, 3575), polarization (PRL, 87, 101301) and non-Gaussianity (PRL, 103, 081303; PRD, 89, 043523). Immediately after discovery of gravitational lensing, Subramanian's models established their usefulness for astronomy (MNRAS, 200, 941; ApJ, 289, 37). He proved general theorems on multiple imaging using catastrophe theory (MNRAS, 219, 333). Subramanian proposed that incomplete relaxation leads to universal cuspy density profiles of dark matter halos (ApJ, 538, 528) and used semi analytical galaxy formation models to understand their abundance and clustering at high redshifts (MNRAS, 377, 285), and to limit neutrino mass (PRD, 83, 123518).

Dr. Vasa has worked extensively on various aspects of experimental nano-optics, plasmonics, semiconductor nanostructures, and spectroscopic techniques for last several years. The focus of her work has been experimental studies of strong light-matter interactions on ultrafast timescale and nanometric lengthscale. She has made systematic and detailed study of strong light-matter interactions in extended hybrid structures comprising an ensemble of quantum emitters in close proximity of a metal nanostructure. Such hybrid nanostructures, supporting strong light-matter interactions are very promising for observing fascinating quantum optical phenomena, and for developing efficient photovoltaics and all-optical devices. In particular, her works on coherent exciton-plasmon interactions, a very first demonstration of real-time Rabi oscillations, optical Stark effect and quantum beats in strongly coupled metal- semiconductor hybrid nanostructures are examples, where quantum optical phenomena have been demonstrated in condensed matter systems at room temperature! Similar investigations were hitherto only possible with pure Rydberg atoms in cryogenically cooled optical cavities. Her work on supercontinuum generation in water, selective bond breaking and ionization of atomic species under the influence of intense fields as well as prevention of optically induced damage in DNA are other noteworthy contributions. In the last few years, her work in India has appeared in journals like Nature Photonics, Physical Review Letters, ACS Nano, ACS Photonics, and Applied Physics Letters and resulted in three patents related to novel fabrication techniques of photonic materials. She is certainly among the leading scientists of her generation in contemporary optics and photonics. Proposer: Prof. Devang V. Khakhar, Seconder: Prof. Dipak K. Palit Ten Best Publications: 1. A.

Member of the NASI: No (YON 2019, Physical Sciences)

Prof. Bambah‘s contributions are in theoretical and experimental particle physics and in mathematical physics. In high energy physics, she proposed a model of multiplicity distributions in high energy collisions based on squeezed coherent states which described two-particle correlations in multiparticle production. Her theoretical Studies of the Quark Gluon Plasma(QGP) addressed the problem of thermalization and stability. The methods from dynamical systems theory have been used by her to study the process of equilibration in the formation of QGP. In particular, she has pioneered the study of Chaos in topological Yang-Mills theories. She has hands-on experience with analysis of data at CERN and contributed to ―QCD Generators at LEP‖. She has used the squeezed state formalism for constructing models of non-equilibrium phase transitions to describe Disoriented Chiral Condensate in QGP and Baryon Asymmetry in the early universe. She has developed a formalism to investigate the dynamics of a relativistic Non-Abelian hot fluid which has been used to investigate topological fluid field configurations and to generalize the Ray-Chaudhuri equation for hot gravitating non-Abelian fluids. She has developed new coherent states in quantum optics, Isospin squeezed states and coherent states of polynomially deformed algebras. Currently, she is leading the collaboration of the University of Hyderabad with The NoVa neutrino experiment at Fermilab and has produced the first Ph.D. from UOH in Experimental Particle Physics. Dr. Bambah has written articles and given seminars to devise methods of inducing and training women to assume leadership roles in physical science. Proposer: Prof. A.K.

Member of the NASI: No (YON 2019, Physical Sciences)

The most important contribution of Dr. Barshilia is in the area of harvesting solar energy through photo-thermal conversion route. He has developed 15 patented compositions of nanostructured coatings of transition metal nitrides and oxides with very high solar absorptance (>0.95), low emissivity (<0.10) and high thermal stability (>500ºC in air) using the concept of graded refractive index along with by providing suitable infrared reflectors, suitable for solar power generation. In order to further improve the thermal stability of these coatings he has put forward the concept of hybrid multilayer coatings, wherein a thin ormosil layer is deposited on top of the solar absorber coating. In yet another significant research, he has developed photo-thermal absorber materials using CNTs and graphene and tailored their composition and optical thicknesses, thus leading to very high optical absorption. Further, he has developed RGO paint along with suitable dopants for solar absorber applications. One of the spin-offs of his fundamental research is in developing a spectral beam splitter for photovoltaic-thermoelectric hybrid system consisting of TCO/metal/TCO. The novel architecture of this system exhibits angular insensitive behavior. Similarly, he has coupled the high temperature solar absorber coating with a thermoelectric generator to develop a proof-of-concept for high performance solar- thermoelectric generator and validated its efficiency through simulation. In order to achieve omni-directional optical absorptance, Dr. Barshilia uses controlled chemical etching of silicon surfaces to make silicon nanowires with very high aspect ratio. The optical performance of these nanostructures has been further improved by decorating silicon nanowires with plasmonic nanoparticles.

BASU, BANASRI (b 1957), Professor (HAG), Indian Statistical Institute, Kolkata

Member of the NASI: No (YON 2019, Physical Sciences)

The nominee,Prof. Banasri Basu,has made pioneering research contributions, primarily in condensed matter physics along with quantum physics and cosmology, demonstrating the relevance of geometric phase in these areas,thereby opening a new vista in theoretical physics. A novel unified framework towards the dynamics of optical and electron vortex beams from the perspective of geometric phase, as proposed by Basu et al., advances substantially the field of vortex beams and highlights connection between Hall effects (spin and orbital angular momentum) and Berry curvature. Further study of interaction between a relativistic electron-vortex beam and laser field deepens our understanding in this context.The nominee‘s idea on the relation between concurrence-a measure of entanglement- and geometric phase provides new insight in quantum information theory and has found applications in the analysis of entanglement dynamics and quantumcriticality. Moreover, Prof.Basu‘s exposition of an innovative analogue of geometric phase, namely, cosmological Berry phase associated with cosmological perturbations of quantum mechanical origin,furnishes new directions in inflationary cosmology. The nominee's recent works on transport coefficients in irradiated Weyl semimetals using Floquet theory and photo-induced entanglement in Floquet magnonic topological insulator are significant in the area of light-matter interaction.For her outstanding research contribution Prof.Basu certainly deserves to be elected a NASI Fellow.

Prof.V. N. Bhoraskar has made significant contributions towards radiation processing of materials and for preparing nanostructures using research facilities developed by him indigenously, namely a 7 MeV Race-Track Microtron, a 14 MeV Neutron Generator and 150 keV Electron & Ion accelerators. Specifically, he prepared substrates for Surface Enhanced Raman Spectroscopy by embedding ~ 3 nm gold nanoparticles on SiO2 nanospheres and detected thiabendazole, crystal violet, and 4-Aminothiophenol at an ultralow concentration ∼10−17 M. The ELCINA-1986 Award was bestowed jointly with B.H.E.L for developing a method based on 6 MeV electron -irradiation, as a superior alternative to the gold diffusion process, routinely used by semiconductor industries. He is credited with the development of a system for simulating radiation environment for space applications, employing electrons, protons, atomic oxygen and UV-radiation. He exposed solar cells and other space quality components to 1 MeV electrons to evaluate any degradation in the device parameters, correlating it with Satellite mission period. Using keV and MeV electrons, he studied (i) in-situ synthesis of metals and semiconductors nanoparticles (ii) diffusion of elements in polymers at room temperature and (iii) radiation -induced damage in semiconductors by measuring lifetime of minority carriers. He successfully correlated ion-energy loss processes in semiconductors by characterizing the 40-100 MeV heavy- ion induced defects, and measured cross sections of several nuclear reactions induced by 14-40 MeV neutrons. Prof. Bhoraskar has published over 215 research papers in peer-reviewed journals, worked in six foreign universities, and delivered thirty invited talks at Universities and research Institutes.

Professor Alokmay Datta's main area of research has been soft materials under planar (monolayers, multilayers, films, membranes) and spherical confinement (droplets and bubbles), and the metal-organic and nano-bio interfaces. Recently he is working on oxide films and glasses. He has played a major role in the pioneering work on observation of planar confinement induced spontaneous ordering in simple and complex fluids, opening a new area of research – the thermal properties of micro and nanofluids. In spherical confinement within droplets, he showed spontaneous segregation of components and ordering of DNA, as a model mechanism of autonomous self-organization within cells. This has made a very strong impact on development of artificial cells. He has conducted extensive research on Langmuir monolayers and multilayers, covering (1) two-dimensional lattices of metal ions forming spontaneously beneath fatty-acid monolayers, (2) two- to three-dimensional transition of monolayers to membranes and clusters, (3) a new type of spontaneously formed bi-layer that can reduce surface tension of water by two orders of magnitude, and (4) two-dimensional pattern evolution through de-mixing in monolayer-nanoparticle systems. The first studies have initiated research on international scale, the second have shown a new way of growing graphene and MoS2, the third is used in water conservation in arid regions, while the fourth have been used to reduce nano-titania optical bandgap by an order of magnitude. His collaborations with groups at Indian Statistical Institute and Institute of Postgraduate Medical Education and Research (SSKM Hospital) have led to new understanding of nanoparticles as anti-viral and anti-bacterial agents.

Sushant has addressed some of the critical issues of a black hole (BH) by systematically investigated the observational consequences of the EHT, searching for new BHs in modified theories of gravity (MTG), contrasting their properties with our knowledge from GR and also investigate in detail, gravitational lensing by MTG BHs in the context of Sgr A* and M87*. He proposed a new robust and accurate method characterizing a haphazard shadow to estimate the parameters associated with a black hole, consistent with the earlier results and applicable to shadow shapes that may not be circular due to noisy data. Although the MTG BHs shadows are smaller and distorted than those of the Kerr BH over a finite parameter space, they satisfy the M87* BH shadow observables within the 1σ bounds deduced by the EHT. The detailed investigations reveal that modelling M87* and Sgr A* as an MTG BH and considering the source star in the Galaxy‘s bulge, the light deflection angle is smaller, images angular separation is more significant, and images magnification is smaller than that for the Kerr and Schwarzschild BHs. Besides finding rotating BHs in MTG, he also tested them against the observations to check their viability for astrophysical BH candidates. In striking contrary to the Kerr- naked singularity, he showed the no-horizon rotating regular spacetimes can cast closed photons ring. He also contributed to regular BHs, higher dimensions, gravitational collapse, generating black holes, and on the black hole as a particle accelerator. Proposer: Prof. M.

Professor Neelima Gupte has made unique and innovative use of insights and techniques from nonlinear dynamics and statistical physics for the analysis of problems which lie at the interface of both fields. The identification of universality properties has been an underlying theme of her work. The method of impulsive synchronisation is a notable contribution that has significant potential applications, as is the use of reconnection strategies to ease congestion in traffic problems, and to enhance the efficiency of load bearing networks. Both these results have been widely appreciated. From a purely theoretical point of view, an important contribution has been the resolution of a long- standing problem, the identification of the universality classes of spatiotemporal intermittency, including the identification of a regime which is in the directed percolation class. In the analysis of traffic on networks, the statistical signatures of congestion and decongestion in the waiting time of messages have been identified. In the case of the branching hierarchical lattice, the critical realisation of the lattice has been found. A new direction being pursued in her work is the application of topological characterisers for revealing the hidden geometry of time series networks, and the identification of their correlations.

The work of Prof. Jha is guided by a strong sense of social needs -- for example, he is actively involved in research in bringing advanced computing technologies in materials science. Owing to continuing advances in computers and algorithms, it is now possible to characterize and design new materials, particularly at the nano-scale, based mostly using simulations. Through computer simulation, his group predicts material-specific behavior that results from the multi-scale structure and associated processes in a material. Mainly, his research work focuses from theory to applications in the field of topological insulators, electronic materials, catalyst, materials at extreme environment, thermoelectric, nuclear materials, drug designing and neurotransmitters has a direct impact to tackle developing world‘s greatest challenges. Taking into account most realistic aspects of a material his theoretical research has involved strong scientific interactions and collaborations with experimental researchers. Therefore, his research has resulted in understanding and interpretation of new observations in experiments and prediction of novel materials. A large number of his outstanding publications in peer-reviewed journals testifies his talents and his quality of research in the DFT-based study. Prof. Jha is an INSA teacher awardee(2018) and also a fellow of the Royal Society of Chemistry(London). He received prestigious TWAS-UNESCO and ICTP associateships. I presume that Prof. Jha‘s work will form an important database for future workers. Prof. Jha quite successfully keeps high tempo of both teaching and research in a university system. This needs to be recognized and nurtured and Prof. Jha is eminently suited for such recognition. Proposer: Prof. Yogendra Pathak Viyogi, Seconder: Prof. Laxman Singh Chamyal Ten Best Publications: 1.

Dr.Brijesh Kumar played a key role in the realization of India‘s largest optical telescope (3.6 m diameter) in Devasthal in Uttarakhand, Himalayas at an altitude of 2500 meter in 2016. The telescope is designed to be technologically advance optical astronomy instrument. He was its Project scientist and was involved in all phases of the project. The telescope now makes fine images and has demonstrated its high capability by resolving a binary star with an angular resolution of 0.4 arcsec. The overall on-site performance of telescope is found to be excellent and at par with the performance of other similar telescopes located across the globe. The telescope is now open to all astronomers in India and abroad. Dr.Kumar was involved earlier in a detailed survey for a high quality astronomical site, and as a result Devasthal was identified as a potential site in the country for setting up new optical telescopes (1,10) Dr. Kumar and his PhD students have made extensive astronomical observations from optical telescopes in India to constrain the physics of explosion and nature of progenitor systems of supernovae explosions. They have also elucidated the circumstellar interaction in supernovae and defining type II supernovae as redshift independent distance indicators.(2-8)Dr.Kumar has also carried out systematic multi-wavelength measurements of aerosols over Nainital a high altitude station in the lower Himalayan region both during night and day time. The finding from this study of a relatively low extinction level over Nainital in the ultraviolet region has played a key role in building up a comprehensive picture of global aerosol distribution.(9) Proposer: Prof.Annapurni Subramaniam, Seconder Prof.Subramaniam Ananthakrishnan Ten Best Publications: 1.

Dr. Dipankar Mandal is a frontier researcher in the area of energy harvesting, in particular piezo and pyro-electric based nano structure materials. Most of his research achievements are mainly work out from India. Recently his group have been demonstrated the way of electricity generation from waste by-product such as fish scale, swim bladder and prawn shell those have enormous future aspects in real-time as well as remote health care assessment. It has high impact in health care sector and portable electronic industries. In other way this approach has another aspects of waste management of biomass like fish waste by-products which consumed a large amount in India every day. So improper disposal of such bio-waste causes environmental pollution. Dr. Mandal and his team have successfully able to fabricate a biocompatible energy generator (published in Nano Energy and APL) that has a higher sensitivity towards mechanical vibrations. It indicates that in near future this type of device, named as nanogenerator have potential application in health care sector, for example it may able to replace batteries of pace-maker and also enable to monitor bio-signal such pulse rate recording. In addition, it also have numerous application in portable electronics devices since it has capabilities to power up every day used tiny electronics devices, thus heavily dependence of batteries and its replacement might be avoided. Recently he has proposed a tribo-electric face mask (Nano Energy, 2021, 79, 105387) which have potential impact to protect from viral infractions that has lots of social impact as well.

Professor Amruta Mishra is a leading researcher in the field of theoretical nuclear physics with expertise on the behavior of hot and dense matter under extremeconditions of temperature, pressure and external fields. Prof. Mishra has made important contributions to the properties of hadrons in a hotand dense medium. Her group has developed and used a model of interacting hadronsrespecting chiral and scale symmetry of the underlying strong interaction. They have used this chiral model of hadrons to calculate medium modification of masses of hadrons as well as their widths in the medium. These calculations are particularly important for the ongoing and planned experimental program of heavy ion collision to study the behavior of strongly interacting matter. Prof. Mishra has also important contribution to the study of superconductivity in quark matter. She, using a nonperturbative method, for the first time, showed the existence of gapless modes in color superconducting quark matter which was later known asbreached pairing in superconductivity. She successfully applied these ideas of quark matter to pairing in ultracold fermionic atoms. Incidentally, her work on cold atoms is the first reserach paper on cold atom superfluidity from India.Apart from being a devoted researcher, she is also an excellent teacher. Many projects that she has done with the master students have resulted in important publications. Proposer: Prof. D. K. Srivastava, Seconder: Prof. Munshi Golam Mustafa Ten Best Publications: 1.

Prof Mittal is regarded as a leading expert by the international scientific community in the field of modeling of anomalous thermodynamic properties of complex solids using neutron scattering experiments and lattice dynamics. His research work on, thermodynamic behaviour of nuclear materials, anomalous thermal expansion, phase transitions and lithium diffusion has led to high impact publications. He has thoroughly investigated graphite samples that had been irradiated with neutrons over 50 years in the CIRUS research reactor, experimentally and by ab-initio simulations. He has for the first time identified neutron-irradiation induced magnetism, atomic-level defect topologies, and mechanism of defect annihilation on heating and release of the Wigner energy. His recent work on alpha-uranium has provided the explanation of multiple Kohn anomalies in uranium, which is a rare phenomenon of fundamental importance. His exhaustive work on negative thermal expansion compounds provided understanding of the underlying mechanism. His studies of superionic conductors identified the linkage between phonons and diffusion in lithium-based battery materials. His extensive studies on several multiferroics and other perovskites provided a clear understanding of the role of structural distortions and their correlation to phonon instabilities, leading to phase transitions in these compounds. Prof. Mittal has been actively involved in neutron instrumentation. The double-focusing neutron monochromator assemblies installed at two of the inelastic neutron spectrometers at Dhruva reactor have resulted in substantial increase in neutron flux at the sample position.

Dr. Nandi started research carrier with reinstallation and modifications of heavy ion accelerator (400kV) and developing beamlines including one for beam-foil spectroscopy at TIFR and made important contribution on multiply excited ions during PhD. Later, contributed well on inner-shell ionization using 3 MV tandem at IOP. Later he setup beam-foil experiments with 14 UD Pelletron at TIFR. In mid-nineties, he initiated experimental atomic physics research programs at IUAC. He setup novel beam-foil spectroscopy technique combining single and two-foil target to avoid blending problems that hinder important aspects of highly charged ions. He explored that beam-foil interaction yields indeed a tenuous high-density plasma. He discovered circular Rydberg states forming in ion-surface collisions, radiative resonant energy transfer during beam-foil interactions, and collision induced intra-shell transitions, which have relevance in astronomy and astrophysics. He put sincere efforts in developing Doppler tuned spectrometer for precise measurements, which showed both self-energy and term energy corrections are required in theoretical calculations. He also developed accelerator mass spectrometry, one of its offshoots enabled discover an entirely new field of ion energy loss at solid surfaces. The laboratory is unique for cross disciplinary science of atomic and nuclear physics. Recently, he discovered influence of strong force on electromagnetic interaction near Coulomb barriers. This field finds significant implications in dark matter detection. He has pursued other cross disciplinary physics programs. His pioneering contributions in mean charge state inside the bulk of the target foil is remarkable. Above all, he is an inspiring teacher cum supervisor and true research inspirator.

The nominee is well-known for his outstanding fundamental research on high-performance ferroelectric and piezoelectric materials. He has over 150 publications, several of them in very highly reputed journals like PRB (> 40), PRL (3), APL (>10), JAP ( > 10), Nature Materials (1), Acta Mater (5), etc. He has contributed extensively towards understanding the structure-property correlations in Na0.5Bi0.5TiO3 family of Pb-free piezoelectrics [PRB 86 134103 (2012); Phys. Rev B88 014103 (2013); PRB; 102, 184113 (2020)]. He is credited with the discovery of a material which exhibits exceptionally large electrostrain (~ 1 %) [Nat. Mater.17, 427 (2018)], and has demonstrated the feasibility of tuning photoluminescence (PL) in ferroelectrics by application of external electric field [PRL 116, 117601 (2016)]. For the first time, his work has shown that rare-earth PL emission signal can be used to understand the degree of structural heterogeneity in ferroelectrics [Phys. Rev. B 98, 094111 (2018); Acta Mater. 145, 429 (2018)]. He has demonstrated that a judicious use of Raman and photoluminescence signals emitted from a rare-earth doped ferroelectric can be used for temperature tuning of the overall emission color, and for design of highly sensitive optical thermometers (Materials Horizons 7, 1101 (2020)).

The nominee has made significant research contribution in the area of quantum transport through low dimensional (meso/nano scale) systems and various recently discovered Dirac materials and topological insulators. Very recently, for the first time in literature, he has theoretically investigated a Cooper pair beam splitter geometry based on Graphene superconductor and showed that it can be a more efficient source of entangled electron pairs compared to other normal materials. Moreover, he has proposed for the first time, how to obtain resonant crossed Andreev reflection and pumped charge out of it in spin-orbit coupled Dirac materials. Also, he has investigated a spin- dependent coupling of Majorana bound states (MBS) mediated by ferromagnetic boundary perturbation in nanowire systems. This is a new proposal as far as transport signature of MBS is concerned. In his earlier career, he has generalized the weak interaction renormalization group method for superconducting hybrid junctions of multiple one- dimensional quantum wires or Luttinger liquid. For a two-wire geometry, he has investigated the possibility of generating pure spin current through such hybrid junctions of Luttinger liquid. Another important aspect he has investigated is the transport signature of zero energy fractional fermion or Jackiew-Rebbi states in one-dimensional nanowires via the two terminal conductance and quantum pumping mechanism.

Prof. P. Singha Deo has worked in a very important research area, namely mesoscopic physics in a rather isolated situation in the absence of sufficient interest in the area within the country, while it has remained to be the most active area of research in developed nations. He has namely worked on charge transport and thermodynamic properties of these small quantum systems and contributed sufficiently to the developing the formalism for understanding these systems. He has pioneered work on understanding electron scattering phase shifts in low dimensional systems and shown that it contains very rich information that can lead to the development of new devices [Nondispersive backscattering in quantum wires]. It can help overcome the most important drawback in finding device application of these systems by bypassing internal details of the system which is rather impossible to know. His works show that the system properties can be determined from the asymptotic wavefunctions and this has been also later found experimentally. He has authored many other well referenced works in the area and mentioned in the section 12. Proposer: Prof. A.M. Jayannavar, Seconder: Prof. P. K. Panigrahi Ten Best Publications: 1. Jayannavar A.

Prof. V.R. Soma, in a span of thirteen years of research career at Advanced Centre for Research on High Energy Materials (ACRHEM), University of Hyderabad (UOH), has established a vibrant ultrafast photonics/spectroscopy laboratory to detect high energy materials (HEMs)/explosives as well as to understand light-matter interactions in a wide variety of materials using ultrashort laser pulses. He has established state-of-the-art ultrafast time-resolved techniques, laser-induced breakdown spectroscopy (LIBS), and ultrafast ablation techniques and investigated dynamics of various materials including HEM‘s. Prof. Rao has developed novel, robust, versatile, low-cost surface- enhanced Raman scattering substrates based on plasmonic nanostructures for the detection of several common explosive molecules using a portable Raman spectrometer, useful for defence applications. Prof. Rao and his group have synthesized several metallic nanoparticles, nanostructures using ultrashort laser pulses and utilized them in detecting explosives at trace levels and biomedical applications. Another outstanding research contribution of Prof. Rao is the development of microfluidic structures in a variety of polymers using the femtosecond laser direct writing (LDW) technique established by him at UOH. These structures found applications in creating lab-on-a-chip devices for medical diagnosis. Recently he has filed a patent for developing few-layer graphene nanocomposites useful as protective coatings against high-temperature corrosion of mild steel (missile canister applications).

BASAK, DURGA (b 1966), Senior Professor, Indian Association for the Cultivation of Science, Kolkata

Member of the NASI: No (YON 2018, Physical Sciences)

Prof. Durga Basak has made pioneering and many original contributions in the development of low-cost zinc oxide (ZnO) nanostructure-based thin films with outstanding photophysical especially UV photodetection properties. Her contributions have greatly advanced the understanding of topics ranging from correlation between the UV photoresponse and emission properties with the intrinsic and extrinsic defects to the development of efficient design strategies for p-n junctions and composites based on ZnO resulting in very high-quality UV sensing properties. Prof. Basak has explored for the first time the photocarrier relaxation mechanism in ZnO nanorods under steady UV illumination and demonstrated that modifying the surface of the nanorods with zinc sulphide, titatium oxide etc can help to achieve improved and steady photodetection properties using such low-cost oxide materials. Her recent series of works on self-powered photodetectors are very promising as these save energy too. By combining ZnO with other low-cost materials to attain a tailored band structures, for the first time, she has demonstrated unprecedentedly high efficiency self-powered broad band photodetection. Prof. Basak has demonstrated so far the highest photoresponsivity value for a low-cost organic-inorganic diode photodetector without externally applied power. Her acclaimed work on simple oxide materials-based photodetectors has attracted significant attraction from the peers. Most notably, she reported a unique and novel combination of graphene quantum dots with ZnO nanowires that can be efficiently harnessed in solar cells. In summary, Prof. Durga Basak has made commendable contributions to basic and advanced applied science in the field of photodetectors and nonconventional energy harnessing. Proposer: Prof. Amlan J.

BHATTACHARYYA, ABHIJIT (b 1969), Professor, Department of Physics, University of Calcutta, Kolkata

Member of the NASI: No (YON 2018, Physical Sciences)

Prof. Abhijit Bhattacharyya has an international reputation as a physicist working in the area of High Energy Physics. His specialisations include QCD phase transition, Heavy Ion Collisions, Compact Stars and Stellar Nucleosynthesis. He has published more than 50 papers in the most reputed and competitive peer-reviewed international journals. His accolades include the very prestigious K.S.Krishnan fellowship and Alexander von Humboldt fellowship. Abhijit has taught for more than seventeen years and supervised seven doctoral and three post-doctoral scholars. One of the major area of work of Abhijit is phase transition in strongly interacting matter. In a large number of publications he has studied different thermodynamic quantities and the fluctuations and correlations of conserved charges, in strongly interacting matter, over the years. These studies have revealed many intricate issues of the medium. He and his group was the first to point out that fluctuations may not scale with volume (PRD91). In a seminal work, in the area of compact stars, Abhijit has found that the conversion of hadronic star to strange star takes place in two steps: first the conversion to 2-flavour quark matter in the strong interaction time scale and second is the conversion to 3-flavour quark matter in the weak interaction time scale (PRC74). The effect of GR was found to have a spectacular result that the conversion front moves in different directions with different velocities (PRC76). Prof. Bhattacharyya is a member of the collaboration board of the Compressed Baryonic Matter experiment at FAIR (Germany).

BINDRA, KUSHVINDER SINGH (b 1963), Associate Director, Laser Group and Head, Laser Applications and Industrial Applications Division, Raja Ramanna Centre for Advanced Technology, Indore

Member of the NASI: No (YON 2018, Physical Sciences)

Dr. K.S. Bindra has worked extensively on research and development of solid state and fiber lasers, operating in cw mode to ultrashort pulsed domain, and their applications in diverse fields. The indigenously developed laser material processing technology has been extensively used in refurbishment of nuclear reactors at KAPS-1, KAPS-2, RAPS and Dhruva reactor. This has resulted in tremendous saving in man-rem consumption and maintenance shutdown time of reactors. He has used ultrashort pulses to investigate nonlinear optical properties of semiconductor nanoparticles and organic materials. The experimental results on semiconductor nanoparticles using degenerate four-wave mixing and Z-scan experiments unraveled previous ambiguities and showed that electron hole pairs generated by nonlinear absorption dominates the nonlinear response. Optical limiting and switching were studied in detail and mechanisms were investigated by conducting Z-scan, nonlinear transmission and scattering measurements. The results and analysis showed that thermal mechanism dominates the signal. The fiber lasers, (a) using the novel concept of multi-mode interference, narrow and tunable cw and Q-switched, (b) ultrashort pulses of nano to femtosecond duration, were designed and developed. The soliton rain was investigated in detail in standing wave cavity for the first time. The Laser Shock Peening (LSP) technique has been studied to improve the fatigue life of leaf springs used in commercial vehicles, and turbine blades. The LSP studies showed mitigating stress corrosion cracking (SCC) of stainless steel. The feasibility of repairing SCC damaged SS304L by laser melting and peening was demonstrated.

DATTA, USHASI (b 1966), Senior Professor "H", Saha Institute of Nuclear Physics, Kolkata

Member of the NASI: No (YON 2018, Physical Sciences)

Dr. Ushasi Datta is an internationally recognized Nuclear Physicist and has significant contributions to understanding of the nuclear structure and to their applications to nuclear astrophysics. She along with her group pioneered the method of extracting unambiguous information on detailed components of the ground-state wavefunction along with quantum numbers of the valence neutron of the nuclei from the measurement of threshold strength along with the gamma-ray spectra following Coulomb breakup. She took major responsibility in establishing the method. The method is now being followed by other groups worldwide for exploring frontiers of the nuclei around the drip-line. Her work in collaboration with international groups showed the disappearance of magic shell gap for neutron-rich nuclei around neutron number 8, 20, 28 which clearly demonstrates urgent need for theories beyond the standard models. She led several pioneering experiments internationally and nationally. She along with her co-workers established the method of measurement of the neutron skin and symmetry energy which are important to model the neutron-star. This work has a direct bearing on understanding neutron star mergers. A small group led by her developed for the first time in India a technological challenging detector (MMRPC) with timing resolution less than 100ps with imaging capability having a high potential for societal applications. Three Ph.D students finished thesis work and another three Ph.D students are working under her supervision.

Research work of Dr. Jagatap covers a wide spectrum of contemporary issues in atomic, molecular and optical physics. In quantum optics, his significant theoretical contributions include key analytical results on resonance fluorescence, non-classicality, cooperative behavior, roles of laser fluctuations, inter-atomic interactions and permanent dipole moments, quantum jumps, photon statistics, squeezed light, electromagnetically induced transparency, spontaneously generated coherence and Kerr nonlinearity and slow light. He provided novel coherent control strategies such as phase control by competing two-photon excitation processes, perfect phase control in two channel problem and recipe for design of molecules for large two/three-photon absorption cross-sections. He was first to demonstrate laser cooling of atoms in India and provided a novel method of control of magneto-optical trap, evidence for new supper-ballistic diffusion and a new technique for measurement of temperature of cold atoms. In experimental quantum optics, his important contributions include sub-natural resolution spectroscopy, modulation transfer and its application to novel frequency offset locking. This work became the forerunner of development of precision atomic clock and ultra-sensitive magnetometer at BARC. In nanophotonics, he has several firsts including multiple Bragg scattering in photonic crystals, inhibition of spontaneous emission in the stop gap, low threshold laser and role of controlled disorder. He contributed significantly to the understanding and consolidation of UV-VUV spectroscopy of several molecules of environmental and astrophysical interest using indigenous INDUS synchrotron facility. His work on novel materials for energy conversion is noteworthy. He contributed to the basic spectroscopy and separation science of strategic technology of laser separation process.

Dr. Sudhir Ranjan Jain has made the most innovative contribution in unravelling a detailed understanding of the eigenfunctions of planar quantum billiards. The analytically exact results for eigenfunctions of a class of chaotic systems known in literature are due to him. This became possible due to certain ―magic connections‖ found by him between between random matrix theory and exactly solvable models. Chladni figures exhibiting the nodal portraits of quantum billiards or acoustic enclosures or electromagnetic cavities were classified in families in his insightful work. He found the nodal domain count for all planar integrable billiards, and thereby established a nodal domain theorem. This work provided the most important advance on the question of nodal domains initiated by Courant and Hilbert more than a century ago. He established some beautiful connections of nodal loops of the eigenfunctions and classical periodic orbits. The difference equation formalism discovered by him realizes algebraic representation of complex geometrical nodal patterns. Other significant innovative contributions include the development of semiclassical methods and trace formulae with the aim of understanding nuclear structure, and, discovering new universality classes of random matrices for systems violating parity and time-reversal symmetries. Currently, he is coordinating the quantum computation activity where alongwith the experimental and technological aspects, he has made original contributions towards protection of qubits from decoherence and noise.

Solar energy is one of the prominent renewable energy sources that could supplement the conventional fuels in the future. Although many materials have been developed in the past, they are not economic as they involve either sophisticated technology or less abundant / toxic materials. Hence, new and novel materials that are more abundant and environmentally safe to handle are highly desirable to develop low cost and user friendly solar cell technology. Dr. Reddy has made solar cells using SnS, Cu2SnS4, SnS2, ZnS, ZnO, ZnMgO materials for the first time and thus has made significant contribution in developing photovoltaic cells using earth abundant and low cost materials. Thin films of these materials have also been grown by him using simple and low cost techniques with ultimate goal of developing cost effective and environmental friendly device technology. Also, one of the critical parameters in the realization of highly efficient heterojunction solar cells, namely, the energy band discontinuities have also been estimated for first time for a variety of SnS-based solar cell configurations. All these aspects are evidenced by well cited publications / patents and award of coveted research fellowships apart from presentations in leading international forums in this upcoming area. I strongly recommend his nomination for the award of fellowship of the National Academy of Sciences, India (NASI). Proposer: Prof. S.K. Joshi, Seconder: Dr. H.C. Kandpal Ten Best Publications: 1. K.

Narayan‘s research work has straddled several different subareas in string theory, some of which involve gauge/gravity duality. In recent times, string theory has emerged as a broad, remarkably consistent framework for addressing a diverse collection of questions involving gravitational physics, often involving remarkable connections or dualities between gravitational theories and quantum field theories without gravity, dubbed as ―holography‖ (or AdS/CFT or gauge/gravity duality). Observables in strongly interacting Conformal Field Theories (CFTs) are mapped to geometric quantities in the dual gravitational Anti de Sitter (AdS) space (in the gravity approximation): e.g. correlation functions map to geodesics while entanglement entropy maps to the areas of minimal surfaces. More generally, remarkable connections have been unravelled between e.g. AdS black holes and Yang-Mills plasmas and so on. Some highlights of his recent research work are: (i) Recently there has been considerable interest in nonrelativistic generalizations of holography (dubbed AdS/CMT) towards addressing questions in strongly correlated condensed matter systems on e.g. quantum entanglement, hydrodynamics and so on. Narayan‘s work involves concrete gauge/string realizations of some of these gravity models (Lifshitz and hyperscaling violating spacetimes), some of which exhibit novel entanglement scaling. (ii) Generalizations of AdS/CFT have included conjectures to accelerating universes (de Sitter space), called dS/CFT duality. In recent work, Narayan has been exploring the geometry of extremal surfaces in de Sitter space. Some of these lead to generalizations of the notions of entanglement to theories with negative norm states, e.g. in simple toy quantum mechanical ―ghost-spin‖ models.

The work done by Dr Tankeshwar Kumar over nearly three decades makes distinct contributions to our understanding of atomic motions in liquids and its interaction with confining walls. Several exact sum rules have been derived by him and his coworkers for the dynamical correlation functions of mass currents, momentum currents and energy current density fluctuations. These results have been used to make acceptable predictions of the transport coefficients of classical fluids and confined fluids. The research work done during past one decade encompasses distinct contribution to the understanding of physics problems pertaining to biological processes and energy conversions. His work in nano scale science finds application in field of human health care. The contribution has also been made to develop new materials for future application in flexible electronics and nano devices for energy conversions. His major scientific contribution lies in the research areas of transport properties, 2D materials, nanofluidics, nanotubes and nanocubes. One of his outstanding work has proven that confinement of liquid at nano- length scale results in local and anisotropic diffusion. Relevance of this work lies in understanding not only with the flow of blood in human arteries but also in understanding the physics of heart attack. Proposer: Prof. K.N.

Dr. K.K. Pant has provided outstanding scientific leadership in the successful development of an Infra-red free electron laser (IR-FEL) at RRCAT, which is the first FEL to lase in the country. FELs involve the advanced technologies of accelerators and lasers in a single system, and X-ray FELs are the fourth generation light sources providing several orders higher photon flux as compared to synchrotron based third generation light sources. The IRFEL at RRCAT has been built indigenously, and lasing in the setup has been achieved at a wavelength of 34 microns with a peak power output > 40 kW, which is set to go up to 2 MW on saturation. This FEL is tunable from 15 – 50 microns, and will pave the way for cutting-edge research in different areas of science and technology for which a commensurate user facility is being setup. Dr. Pant has made valuable contribution to the design and indigenous development of the IR-FEL injector linac system, which is capable of delivering an electron beam of 15-25 MeV energy with the required beam quality, consuming ~ 12 MW peak microwave power. Dr. Pant has also contributed to the design, development, tuning and testing of a laser photocathode RF gun - a state-of-the-art injector required for building fourth generation light sources in the future. Novel algorithms have been developed for the design and tuning of this and other accelerating structures with desired RF properties as part of this activity. Proposer: Dr. P.A.

TRIBEDI, LOKESH CHANDRA (b 1963), Senior Professor (E), T I F R, Mumbai

Member of the NASI: No (YON 2018, Physical Sciences)

Prof. L. C. Tribedi has developed multi-faceted and cutting-edge research program and made several seminal discoveries in the field of inter-disciplinary science of atoms, large-molecules and clusters. Prof Tribedi is a world- authority in taking-up a pedagogically clean fundamental experiment on the Young type electron interference using homonuclear diatomic molecule as a nano-scale double-slit. Provided unambiguous experimental evidence of interference using fast-ions, photon and electron collisions which gave rise a new direction to the field. Extending these studies to interdisciplinary realm he explored influence of many-body effect in e-emission from DNA/RNA-base molecules and water. He explored first time the unusually large e-emission or radio-sensitization for nano-particle inserted biomolecules which will play a crucial role in hadron-therapy of cancer. He showed unambiguously this effect arises due to giant resonance. Direct evidence of dipolar and quadrupolar plasmon resonance in single-nano-particle C60 was provided for the first time-through ―plasmon-electron‖ detection. Provided unique evidence of UV-plasmon resonance in PAH molecules crucial for astrophysics, astrochemistry and UV plasmonic devices. He was pioneer to unearth the influence of collective excitation which was crucial for modelling radiation damage and radio-sensitization. Demonstrated existence of fluorescence-active doubly excited states in He-like heavy-ions contrary to the conventional quantum selection rules. His series of meticulously planned experiments has not only generated new experimental fronts but also guided the theorists to develop newer models. He is responsible for indigenous development of world- class experimental-setups, such as: state-of-the-art low energy ECR-ion-accelerator laboratory for forefront research in interdisciplinary sciences, and several electron-, Recoil-ion-momentum, x-ray spectrometers etc. Proposer: Prof. E.V.

Pankaj Agrawal works broadly in two areas -- HEP Phenomenology and Quantum Information. He obtained his PhD under Prof. Stephen D. Ellis. They proposed new signatures of the Higgs boson, top quark and other new heavy quarks. His other notable works in HEP phenomenology are proposals for detecting T-violation in rare Kaon decays, novel signatures of the Higgs boson with the bottom-jet or tau-jet tagging. Theirs was one of the earliest works in 2001 in computing contribution of pentagon-type diagrams to collider processes. They have also developed packages for such calculations. The package OV Reduce is for the reduction of tensor integrals to scalar integrals. In India, he has been a leading figure in one-loop multi-leg computations. In Quantum information, His contribution is to probabilistic versions of protocols, such as teleportation and superdensecoding. In a major contribution, a information- theoretic measure to quantify and characterize the entanglement of multipartite systems is proposed. They have also found new ways to measure entanglement of higher-dimensional bipartite systems. They have also found new Bell inequalities for multipartite systems. They have computed new trigonometric sums which will be part of major handbooks. Moreover, one of his publications is termed as "famous paper" in the classification of HEP Inspire database for citation. I expect him to continue to do significant work. I strongly recommend a fellowship for Prof. Pankaj Agrawal who certainly deserves it. Proposer: Prof. H. S. Mani, Seconder: Prof. Sudhakar Panda Ten Best Publications: 1.

Selected major scientific contributions of Prof. Sudip Bhattacharyya, who studies extreme physics of superdense celestial objects, e.g., neutron stars and black holes, are listed here.In 2007, he led the discovery of a broad relativistic X-ray spectral iron emission line from an accreting neutron star. This opened up a new way to probe the superdense degenerate stellar core matter and the strong gravity regime, and this newly established field provides a major scientific motivation for current and future X-ray satellites. It is a holy grail of modern physics to find a definitive proof of the existence of stable stellar-mass black holes. In 2020, he, with his Ph.D. student and two other collaborators, reported heretofore by far the most significant signature of such black holes using observations in X-rays. A fundamental problem of physics is to identify plausible naked singularities by distinguishing them from black holes. During 2017-2019, he, with his Ph.D. student, postdoctoral fellow and other collaborators, found multiple ways to observationally achieve this goal. In 2018, he and his postdoctoral fellow reported the first indication of the gravitomagnetic monopole, which is a fundamental aspect of physics. During 2017-2021, he showed that the traditional way of spin evolution computation for accreting neutron stars is inadequate. He also inferred that the neutron star PSR J1023+0038 should emit gravitational waves continuously. Prof. Bhattacharyya was awarded the NASA Space Science Achievement Award, and is the current project manager of the Soft X-ray Telescope aboard the Indian astronomy satellite, AstroSat.

Subir Das has made outstanding contributions to fundamental aspects of phase transitions and related phenomena occurring in living and nonliving matters. Through powerful combinations of simulations, finite-size scaling and other statistical mechanical theories, he extracted universal features in equilibrium and nonequilibrium systems and achieved deeper understanding. He has published high quality works that (i) demonstrated how curvature-dependent interfacial tension governs the kinetics of phase transitions and predicted its anomaly in the vicinity of the critical points or second order phase transitions; (ii) developed analytical methods for determination of the contact angle and line tension relevant to a wetting transition, by taking care of interfacial fluctuations near criticality in thermodynamic manner; (iii) obtained quantitative understanding of the universality in transport anomalies near the critical points of fluid-fluid phase transitions, effectively using the finite-size scaling method, and confirmed the fundamental predictions of renormalization group and mode-coupling theories; (iv) pointed out the significance of fractal morphology and hydrodynamics in kinetics of phase separation; (v) uncovered the scaling laws of aging in various types of nonequilibrium systems and identified the differences based on dimensionality, order-parameter conservation and relevance of hydrodynamics; (vi) demonstrated the validity of dynamic scaling laws of nonequilibrium statistical mechanics of passive matter in the behavior of active matter; (vii) showed how scaling theory can be effectively used to predict disease spread. His works have significantly enhanced our understanding of phenomena like nucleation, wetting, criticality, growth and aging, which are directly relevant to experiments on hard, soft and living matter, spanning many disciplines.

Developing the knowledge of energetic materials through computer simulation provides a safer and convenient way to study the physics and chemistry of energetic materials, which is cost effective and the candidate has done a quite extensive and dedicated research over the past years on this topic. The main part of the candidate‘s work is focused towards the fundamental understanding of these materials and his theoretical predictions guide the experimentalists in proper designing of these energetic materials and his work, on these materials [J. Phys. Chemistry C 123 (2019) 2114; Journal of Chemical Physics 145 (2016) 064706; Physical Chemistry Chemical Physics 17 (2015) 29210] are well cited.Understanding the crystal structure of NH4ClO4 is an evergreen problem because of the contradicting reports by several experimental groups in the literature. The candidate tried to resolve this issue in his recent work [J. Phys. Chemistry C 123 (2019) 2114] in which he proposed that NH4ClO4 will have polymorphic structures with very low energy difference under ambient conditions. In addition, the candidate computed the phonon dispersion curves for the first time to resolve the issue of structural stability. In the case of ADN, the candidate was the first one to predict the strengthening of the hydrogen bonding in ADN above moderate pressure of about 5 GPa [Journal of Chemical Physics 145 (2016) 064706]. The candidate work on N4H4 polymorphs [Physical Chemistry Chemical Physics 17 (2015) 29210] tried to shed light in understanding the high-pressure behavior of high energy density material NH4N3.

I know Prof. Binay Kumar for decades and am impressed by his work ethics and dedication for scientific commitments. His major contributions in the field of single crystals, ceramics, nanoparticles and devices are: He has developed the know-how of preparing ceramic and crystals of many technologically important materials like High-Tc Superconductors, piezoelectric binary perovskites like PZN-PT, BNKT and Non-linear Optical organics. Many of these works are path breaking and he has achieved excellent properties of international standard by innovative crystal engineering. [Physica C 411 (2004) 180; Cryst. Res. Technol. 44, (2009) 915; CGD 15 (2015) 867; Scripta Materialia99(2015)77]. He has designed a low cost modified Czochralski set up (used for crystal growth of high melting point materials) to grow large organic crystals of low melting point for the first time [CrystEngComm 20 (2018) 624]. He showed that ‗ferroelectricity‘ can be induced in ZnO nanoparticles with doping and morphology tuning and achievedmany-foldhigherpiezoelectricity[JALCOM816(2020)152491]. He used these crystals and nanoparticles to fabricate devices like flexible piezoelectric energy harvesters sufficient to feed body-bound electronic gadgets and patch antennas for GHz communication [JALCOM 767 (2018) 1003; JCG 450(2016)74].He has published nearly 160 research papers, completed seven major projects, guided 18 Ph.D. scholars and taught/mentored nearly 8000 M.Sc. students and delivered over 60 invited talks.

MAHADEVAN, PRIYA (b 1970), Senior Professor, S.N. Bose National Centre for Basic Sciences, Kolkata

Member of the NASI: No (YON 2017, Physical Sciences)

Dr. Priya Mahadevan is a condensed matter theorist who has made significant contributions in the study of electronic and magnetic properties of materials. Recently there has been a lot of interest in studying multiferroics (materials which exhibit both magnetism and ferroelectricity) with a view to use them in new generation electronic devices. A limitation that has often been encountered has been that the largest ferroelectric polarizations are seen in systems which have no d electrons, while the latter are needed for the material to exhibit magnetism. Dr. Priya Mahadevan adopted a rather unusual route to search for high polarization multiferroics. As large values of polarizations have lattice distortions as their origin, she along with her students tried to examine why the distortions found in systems which had no d electrons did not survive at finite d electron count. In Phys. Rev. B 87,214110 (2013) they gradually increased the d count and showed that one had the unusual situation where orbital ordering favoured the presence of polar distortions. The ideas of the dilute doping limit were extended to design bulk heterostructures which were both magnetic and ferroelectric (Phys. Rev. Lett 111, 077601 (2013). A set of recent papers from her group(Phys. Rev. B 86, 104406 (2012), Phys. Rev. B 89, 134416 (2014)) represent a paradigm shift of how one understands magnetism. A class of 4d and 5d transition metal oxides have been identified which have high magnetic temperatures, higher than their 3d transition metal containing counterparts.

MOHANTY, SUBHENDRA (b 1960), Senior Prof.(H), Retired; Physical Research Laboratory, Navarangpura, Ahmedabad

Member of the NASI: No (YON 2017, Physical Sciences)

Prof. Subhendra Mohanty introduced the emergent field of Astroparticle Physics in India proposing many new and unique ideas correlating gravity as well as astrophysical observations with particle physics. His main contributions is in testing particles physics of axions, neutrinos, supersymmetry using different astronomical observations like pulsar timings, WMAP and Planck observations of CMB. His were among the the earliest papers on testing neutrino properties like magnetic moment, life-time and long-range leptonic interactions from experimental observations of solar, atmospheric and astrophysical neutrinos. His major contribution is in the study of particle physics aspects of Inflation where starting from 2006 he continues to contribute new ideas towards the goal of arriving at the correct theory of inflation in general relativity and particles physics using the observational evidence. Specifically, he showed that during cosmic inflation there can be large deviations from well established scale invariant perturbation spectra of both scalar and gravitational waves if inflation was preceded by a radiation dominated era. This can be tested from the analysis of the B-mode polarisation signal of CMB.Prof. Mohanty is a unique physicist in the country who has initiated and significantly contributed to research in interdisciplinary areas of gravity, particle physics, cosmology and the various interfaces of these fields He has six papers published in Physical review letters on the topics of astroparticle physics and inflation and has written monograph on ―Advances in Astroparticle Physic and Cosmology‖ which was published by Springer in Dec 2020.

PANIGRAHI, KAMAL LOCHAN (b 1975) Professor, Indian Institute of Technology Kharagpur

Member of the NASI: No (YON 2017, Physical Sciences)

In the last few years Dr. Panigrahi's research focus of attention has been the study of AdS/CFT correspondence and integrable deformations thereof, D-branes and string theory in various time-dependent exact string backgrounds by using the methods of conformal field theory and the eDective field theory. He has also contributed in the study of higher Spin gauge theory and string inspired cosmology in various D-brane models. In JHEP 1506 (2015) 057 and JHEP 1409 (2014) 048 various semiclassical rotating and pulsating string has been studied in integrable deformations of AdS to have better understanding of the AdS/CFT dualities in lesser supersymmetric backgrounds. JHEP 0806 (2008) 065, JHEP 0711 (2007) 011, JHEP 0704 (2007) 099 quite extensively argued the role of semiclassical strings in computing the string theory side story of the BPS operators in various curved backgrounds whose boundary theory is misnomer. Phys.Rev. 074 (2006) 085029 discussed a novel way of constructing bosonic triplet in higher spin gauge theory on AdS space. In JHEP 0509 (2005) 023, and JHEP 0505 (2005) 018 Dr. Panigrahi with collaborators studied the D-branes and the case of particle production in various group manifolds in string theory which allows one to understand the time dependent phenomena in string theory. To have more a clearer picture of geometric realization of open string tachyons of string theory, in Phys.Lett. 8601 (2004) 64-72, the time dependent motion of D-brane in arbitrary Dp-rane background was analyzed. In JHEP 0711 (2007) 017, and Phys.Lett. 8712 (2012) 10-15 various inflationary situation of such D-brane motion was studied and JHEP 0706 (2007) 015 classifies geometric realization of various unstable branes with tachyons in the worldvolume.

SEN, PRASENJIT (b 1969), Professor-H, Harish-Chandra Research Institute, Prayagraj

Member of the NASI: No (YON 2017, Physical Sciences)

Prof. Sen has made pioneering contributions in the area of atomic clusters. His research on transition metal (TM) doped alkali clusters led to the discovery of magnetic superatoms giving rise to possibility of bottom-up design of novel nano-materials. Prof. Sen and his collaborators showed that VCs8, ligated MnAu24, FeMg8 and FeCa8 clusters behave as magnetic supertaoms. VCs8 superatoms can be used to make larger assemblies with fascinating magnetic properties. It was later suggested that two VCs8 clusters together act as an efficient spin filter which can find use in molecular electronics. These path-breaking works received immediate worldwide attention and media coverage. Prof. Sen‘s path-integral quantum Monte Carlo (PIMC) calculations on melting of flux line lattice is a seminal work in the area with broader implications for effects of quenched disorder on first-order phase transitions. This was the first PIMC calculation with 1000 particles, a new technical feat at that time. His Monte Carlo calculations conclusively established that KO2 has a magnetic ground state unexpected for an alkali-oxide. KO2 was also found to have an orbital order in p-orbitals, the first known compound of its kind. Prof. Sen has made well cited contributions to the areas of one-dimensional atomic wires, hydrogen storage, semiconductor surfaces, and various two- dimensional electronic materials. He is a versatile scientist with wide impact. Proposer: Prof. Alok K. Gupta, Seconder: Prof. J. K. Bhattacharjee Ten Best Publications: 1. P. Sen, N. Trivedi, and D. M.

The group led by Prof. Taraphder is internationally prominent and the leading theoretical group in India on the Oxide hetero-interfaces, a lively recent field, home to strange metallic phases at the interface, and oxide electronics. In an incisive series of contributions, they established the Kosterlitz-Thouless nature of superconducting transition, predicted Majorana bound states, being searched for internationally. In a brilliant piece of work, his group has recently proposed the Planar Hall Effect in Weyl semimetals which is now observed and acknowledged worldwide. His papers on GdI2 are the only theories that explain its unconventional metallic ferromagnetic state. Their alternative scenario, sans nesting, and using excitonic fluctuations condensing at low temperatures to a charge-density-wave (or superconducting) state, explains the unique observation of enhanced coherence of the charge-density-wave states in transition metal dichalcogenides. Their theory has, of late, gained considerable acceptance. Their work on the unusual transport properties of Barium Bismuthate is a standard reference in the subject even after 25 years. They explained the extraordinary difference between the optical and transport gaps using electronic correlation, proposing a new mechanism. He and Coleman had predicted ―Charge Kondo Effect‖ theoretically, which was discovered 14 years later by Geballe‘s group in Stanford University. They also predicted orders of magnitude rise in accompanying superconducting Tc. This was subsequently discovered, and possibly plays a role in superconductivity in elemental Bi. The sustained high level work of Prof. Taraphder has, almost single-handedly, put his department on the national and international map in condensed matter physics. Proposer: Prof. T.V.

Prof. Mahendra Verma has made fundamental contributions in theoretical and computational turbulence. In particular, he (with Eswaran and Dar) formulated ―mode-to- mode energy transfers‖ in turbulence that is widely used for the computation of energy flux and shell-to-shell transfer rates. He also devised novel tools to quantify anisotropic turbulence. Prof. Mahendra Verma has focused on magnetohydrodynamic and buoyancy-driven turbulence. In a significant development, using field-theoretical tools and extensive numerical simulations, he demonstrated Kolmogorov-like turbulence phenomenology for magnetohydrodynamic (MHD) turbulence. He and his collaborators have computed various energy fluxes of MHD turbulence, which are useful for understanding magnetic fields of the Sun and the Earth. Prof. Mahendra Verma showed that turbulence in thermal convection has significant similarities with fluid turbulence, notably their energy spectrum, fluxes, and structure functions. He and his group have also discovered valuable results on scaling of the Reynolds number and dissipation rates in convection. These results were derived using novel theoretical tools and extreme computing. Prof. Mahendra Verma has pioneering contributions in high-performance computing of turbulent flows. For example, the Fast Fourier Transform and pseudo-spectral solver TARANG developed by his group are being widely used by many researchers. Proposer: Prof. Jayant K.
