RESEARCH EXPERIENCE Aix-Marseille Université - Campus St. Jérôme, Marseille, France June 2014 – August 2014 Laboratoire Physique des Interactions Ioniques et Moléculaires (PIIM) Center National de la Recherche Scientifique (CNRS) Internship Advisor: Dr. Grégoire Danger ([email protected]) Optimization and quality control of the experimental set-up for Project VAHIIA (Volatile Analyses from the Heating of Interstellar/cometary Ice Analogues). Formation of cometary ice analogues using cryogenic and high vacuum technologies, as well as subsequent analysis of volatile organic compounds and organic residues coming from the heating of these analogues using GC-MS and Orbitrap high-resolution mass spectrometry. The goal of my research was to obtain information on potential chemical reactivity occurring inside cometary grains as a point of reference for data incoming from ESA’s Rosetta mission. Massachusetts Institute of Technology, Cambridge, MA USA January 2014 – May 2014 Department of Earth, Atmospheric, and Planetary Sciences MIT Undergraduate Research Opportunities Program/Wellesley College Senior Thesis Advisors: Dr. Tanja Bosak ([email protected]), Dr. Vanja Klepac-Ceraj ([email protected]) My thesis concerns cyanophycinase mediation in carbon and nitrogen cycling of benthic, marine, Subsection III cyanobacterial mats. I am currently investigating of cyanophycin expression in various regions of the mat as it relates to morphological and ecological observations using immunoassays. I take geochemical measurements of local N concentration, nitrate vs. ammonia, N-fixation, and also conduct high-resolution stable-isotope mapping of labeled bicarbonate 13 - (H CO3 ). I will use these data in conjunction with morphological observations and gene sequencing (16s rRNA, nifH, and CphA). I hypothesize that cyanophycin composition and function will vary according to species composition and nutrient availability, as such results have been implied for freshwater cyanobacteria from Yellowstone National Park, WY USA. NASA Ames Research Center, Moffett Field, CA USA June 2013 – August 2013 Exobiology Branch SSX Intern Advisor: Dr. David J. Des Marais ([email protected]) I continued to culture and characterize (via 16s rRNA sequencing) the same strain of anoxygenic purple non-sulfur bacteria species I had worked with in summer 2012. I also cultured several strains of Cyanidiales and Chlorella from Sulphur Works and Devil’s Kitchen localities. I developed a trial run of a volcanic rock dissolution experiment for the 2013-2014 Lassen Astrobiology Student Intern Program, which included mineral analysis of solid precipitates via XRD and comparison to alteration materials found in analogous hydrothermal sites in Lassen Volcanic National Park. I worked with the Geographic Information Systems software ArcGIS to develop a 3D hydrogeological map of California’s Southern Cascades. I participated in education and public outreach efforts at the 2013 Lassen Dark Sky Festival by giving field work Updated April 2016 demonstrations and public talks discussing the characteristics of Lassen that make it a Mars analogue site. NASA Ames Research Center, Moffett Field, CA USA June 2012 – August 2012 Exobiology Branch SETI Institute Research Experience for Undergraduates Advisor: Dr. David J. Des Marais ([email protected]) My research focused on early habitable environments and the evolution of complexity in support of the NASA Astrobiology Institute. Specifically, my work included conducting pure culture isolation and fatty-acid methyl ester (FAME) characterization of acid-tolerant purple non- sulfur bacteria from hydrothermal features in Lassen Volcanic National Park. I also participated in education and public outreach efforts by contributing to curriculum development of a NASA- sponsored astrobiology internship for high school junior and seniors – the Lassen Astrobiology Student Intern Program. Massachusetts Institute of Technology, Cambridge, MA USA May 2011 – August 2011 Department of Earth, Atmospheric, and Planetary Sciences MIT Undergraduate Research Opportunities Program Advisor: Dr. Tanja Bosak ([email protected]) In the Bosak Lab, I examined the microstructure of microbial mats produced by cyanobacteria under laboratory-controlled conditions, and compared these structures with those of fossils belonging to their 1-3 billion year-old (Ga) stromatolite ancestors. This process was developed to gain an understanding of the environmental conditions that existed in intertidal zones during the Precambrian, as well as the chronology of conditions that allowed for the rise of atmospheric oxygen – and consequently complex aerobic life – on Earth. In addition to hands-on research, I conducted literary research through my translation of primary scientific literature on the same subject from Soviet-era Russia. From this literary search, I began the process of reconstructing the stromatolite classification system using a dichotomous key approach to classify fossil stromatolite forms based on quantitative, morphological characteristics ranging from most general (macroscopic measurements), down to most subtle (i.e. microstructure) features. TEACHING EXPERIENCE Wellesley College, Wellesley, MA USA September 2012 – May 2014 Department of Astronomy Teaching Assistant Supervisor: Dr. Stephen Slivan ([email protected]) ASTR 102 – Introductory Astronomy Laboratory I served as an assistant laboratory instructor for introductory astronomy courses at Wellesley College. My training included knowledge of optics for both refracting and reflecting telescopes, which were used in my instruction for this course. I am also a licensed operator of two Victorian- era refraction telescopes (12” and 6” diameter lenses) and their respective domes for course- required student observing.
