Department Chair; Murray and Martha Ross Professor of Environmental Sciences; Harvard College Professor
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.
Sturgis Hooper Professor of Geology; Professor of Environmental Science and Engineering; Director, Harvard Univ. Center for the Environment; Director, Science, Technology and Public Policy Program, HKS; Area Chair for Environmental Science and Engineering
Daniel P. Schrag is the Sturgis Hooper Professor of Geology at Harvard University, Professor of Environmental Science and Engineering, and Director of the Harvard University Center for the Environment.
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.
Pamela and Vasco McCoy, Jr. Professor of Oceanography and Applied Physics
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.

Title:"Convective aggregation and cloud feedbacks in a near-global aquaplanet cloud-resolving model"
Abstract: Near-global aquaplanet simulations of 100 or more days with 4 km horizontal resolution and no cumulus or boundary-layer parameterization are now computationally affordable for academic research. They are attractive for problems for which the multiscale organization of cloud systems plays an essential role and specified zonally-symmetric sea-surface temperature is a useful simplification. Two...
The Schrag lab uses isotope ratio mass spectrometry (IRMS) to analyze environmental samples for stable isotopic content. This research yields information about global climate change in the geologic past, which can lead to a better understanding of climate change in the future.
Brad Lipovsky is an Earth Scientist who primarily studies glaciology, tectonics, and volcanology using geophysical observations, mathematical physics, and numerical simulations. On-going research focuses on the physics of the glacier-atmosphere, glacier-bed, and glacier-ocean interfaces.
