STORER LECTURESHIP IN LIFE SCIENCES Edward DeLong Morton and Claire Goulder Professor Departments of Civil Engineering and Biological Engineering, Massachusetts Institute of Technology Professor DeLong is an internationally recognized marine microbiologist for his groundbreaking work on ocean microbiology and ecology. He is renowned for his discovery that bacteria use rhodopsin in converting sunlight to biochemical energy in marine microbial communities, revealing a previously unknown component in the Earth’s carbon and energy cycles. He has developed and applied novel methods for phylogenetic identification, functional characterization, and quantitation of (individual) bacterial species in culture‐independent ways leading to metagenomic analyses of marine bacterial populations. His laboratory has discovered new taxa, metabolic pathways, and photosynthetic pigments in marine bacteria, materially changing the field of marine microbial ecology. Dr. DeLong is an elected Fellow of the American Academy of Microbiology, the American Academy of Arts and Sciences, the American Association for the Advancement of Science, and the National Academy of Science. Ed DeLong was born in Sonoma California, received a B.S. degree from UC Davis and a Ph.D. from The Scripps Institute of Oceanography. He will receive the 2012 Outstanding Alumni award from the College of Biological Sciences at the College Celebration following his lecture on Thursday, October 4. Professor DeLong will present two lectures in this series Public Lecture: Scientific Lecture: Wednesday October 3, 2012 Thursday October 4, 2012 “Microbial community genomics and “Exploring Earth’s infinite microbial transcriptomics reveal structure, biosphere, from genomes to biomes” function and dynamics in marine planktonic assemblages” 4:10 PM Conference Center, Ballroom 4:10 PM ARC Ballroom B Sponsored by To make an appointment with the speaker Storer Endowment in Life Sciences contact Martina Newell-McGloughlin at College of Biological Sciences [email protected].

Reviewer Biographies
Biosciences Area Review 2015 Lawrence Berkeley National Laboratory Reviewer Biographies Janet Braam, Ph.D., Rice University Janet Braam has a diverse scientific background, being involved in research that spans from translation medical research to basic plant cell biology. She received her PhD in Molecular Virology and Biology from the Sloan-Kettering Division of the Cornell Graduate School of Medical Sciences, elucidating the roles of influenza viral polymerase subunits. She then joined Stanford University School of Medicine as an NSF postdoctoral fellow in plant biology. Dr. Braam’s research at Stanford led to the discovery that plants turn on genes in response to touch and shed light on the importance of calcium signal transduction in mechanical perturbation responses in plants. In 1990, Dr. Braam joined the faculty at Rice University and rose through the ranks. She has had continual federal grant support and served on diverse grant and advisory panels Dr. Braam’s research contributions include uncovering roles of calcium-binding and cell wall proteins in plant responses to environmental stress, and elucidating aspects of nitric oxide signaling, autophagy regulation, and jasmonate dependent defense. Most recently, her research focus also includes the role of the circadian clock in plant defense, the complex regulation of chlorophyll biogenesis, phytohormone regulation, and autophagy control. Her discoveries in basic plant biology have potential translational application in drug discovery, crop nutrient enhancement, and nanomaterial toxicity analysis in plants.

V. Rich, p. 1 Virginia Rich [email protected] 393 Broadway #20 • Cambridge, MA 02139 • 617-694-5087 RESEARCH INTERESTS I am interested in understanding the dynamic link between microbial community ecology and global biogeochemistry. In my thesis work I am applying a novel microarray platform to track the changes in marine microbial communities across environmental gradients, in concert with metagenomics analyses, and have previously examined changes in terrestrial methane-oxidizing microbial communities under simulated global change conditions. My goal is to continue to map these complex interactions, since we remain far from understanding their baseline conditions. In addition, I’d like to incorporate a personal or collaborative emphasis on modelling, prediction and potential remediation opportunities.

Press Release Wednesday July 2, 2008
Press Release Wednesday July 2, 2008 New Pathway for Methane Production in the Oceans Honolulu, HI – A new pathway for methane production has been uncovered in the oceans, and this has a significant potential impact for the study of greenhouse gas production on our planet. The article, released in the prestigious journal Nature Geoscience, reveals that aerobic decomposition of an organic, phosphorus-containing compound, methylphosphonate, may be responsible for the supersaturation of methane in ocean surface waters. Methane is a more potent greenhouse gas than CO2 on a per weight basis. Although the volume of methane in the atmosphere is considerably less than CO2, methane is much more efficient at trapping the long wavelength radiation that keeps our planet habitable but is also responsible for enhanced greenhouse warming. Today, between 20- 30% of the total radiative forcing of the atmosphere is due to methane. Terrestrial sources of methane production are well known and studied (including extraction from natural gas deposits and fermentation of organic matter), but those known sources did not account for the levels of methane observed in the atmosphere. David Karl, an Oceanographer in the School of Ocean and Earth Science and Technology at the University of Hawaii at Manoa and lead author of this paper, was interested in this “methane enigma” and why the surface ocean was loaded with methane, over and above levels found in the atmosphere. When looking at the literature, Karl found a possible solution to the A conceptual view of the role of sunlight in enigma, in the compound methylphosphonates, a very unusual organic producing methylphosphonate through food‐web compound only discovered in the 1960s.
