Ann Pearson is the Murray and Martha Ross Professor of Environmental Sciences. Her research focuses on applications of analytical chemistry, isotope geochemistry, and molecular biology to biochemical oceanography and Earth history. 

Through study of the “how, when, and why” of microbial processes, her work yields insight about environmental conditions on Earth today, in the past, and about potential human impacts on our future.  Recent projects have focused on the carbon and nitrogen cycles and on pathways of lipid biosynthesis.

Pearson received a Fellowship for Science and Engineering from the David and Lucille Packard Foundation in 2004, a Radcliffe Institute Fellowship in 2009, and was named a Marine Microbiology Initiative Investigator of the Gordon and Betty Moore Foundation in 2012. She holds a Ph.D. in Chemical Oceanography from the MIT/WHOI Joint Program in Oceanography, where she was awarded the C. G. Rossby Award for Best Dissertation in the Program in Atmospheres, Oceans, and Climate; and a B.A. in Chemistry from Oberlin College.

Daniel P. Schrag is the Sturgis Hooper Professor of Geology, Professor of Environmental Science and Engineering, and Co-Director of the Science, Technology, and Public Policy Program.

Schrag studies climate and climate change over the broadest range of Earth history. He is particularly interested in how information on climate change from the geologic past can lead to better understanding of anthropogenic climate change in the future. In addition to his work on geochemistry and climatology, Schrag studies energy technology and policy, including carbon capture and storage and low-carbon synthetic fuels.

From 2009-2017, Schrag served on  President Obama’s Council of Advisors on Science and Technology.  Among various honors, he is the recipient of the James B. Macelwane Medal from the American Geophysical Union and a MacArthur Fellowship. Schrag earned a B.S. in geology and geophysics and political science from Yale University and his Ph.D. in geology from the University of California at Berkeley. He came to Harvard in 1997 after teaching at Princeton.

Eli Tziperman joined Harvard as a Professor of oceanography and applied physics in 2003.  His research interests include large-scale climate and ocean dynamics, including El Nino, thermohaline circulation, abrupt climate change, glacial cycles and equable climates; advanced methods of ocean data assimilation. 

He teaches courses in oceanography, climate and applied math.  Before Joining Harvard he was a post doc to a prof, 1988-2003, at the Weizmann institute of science.  He holds a BA in physics and mathematics, Hebrew University, Jerusalem, and a PhD in physical oceanography from the joint program of MIT and Woods Hole Oceanographic Institution.
