Stonington Professor of Engineering and Atmospheric Science Area Chair for Environmental Science and Engineering Professor of Chemistry and Chemical Biology; Affiliated Faculty Member of Earth and Planetary Sciences
Research in the Keutsch group is aimed at improving our understanding of photochemical oxidation processes of volatile organic compounds (VOCs) that produce tropospheric ozone (O3) and are central to secondary organic aerosol (SOA) formation. O3 and aerosol affect human health and climate, and uncertainties in the radiative effects of aerosol comprise the largest uncertainties in current estimates of anthropogenic forcing of climate. Our scientific approach builds on enabling new field observations of key VOC oxidation intermediates (OVOCs) via instrumentation and method development.
Gordon McKay Professor of Environmental Chemistry Professor of Earth and Planetary Sciences
Elsie M. Sunderland is the Gordon McKay Professor Environmental Chemistry at the School of Engineering and Applied Sciences and in the Department of Environmental Health in the Harvard School of Public Health, and an affiliated faculty member of the Department of Earth and Planetary Sciences. She is a Faculty Associate in the Harvard University Center for the Environment and the Harvard Center for Risk Analysis.
Research in the Sunderland Lab focuses on how biogeochemical processes affect the fate, transport and food web bioaccumulation of trace metals and organic chemicals. Her group develops and applies models at a variety of scales ranging from ecosystems and ocean basins (e.g., the Gulf of Maine, the North Pacific and Arctic Oceans) to global applications to characterize how changes in climate and emissions affect human and ecological health, and the potential impacts of regulatory activities. Her group also makes key measurements of chemical concentrations and reaction rates in environmental samples (natural waters, sediments, and aquatic biota) and humans (hair, blood) to parameterize and evaluate environmental models.
Ongoing research is elucidating the biogeochemical cycling of compounds with contrasting physical and chemical properties that can be used to obtain insights into the varying exposure pathways and environmental lifetimes for industrial chemicals. The innovation in this work is to quantitatively analyze the entire exposure pathway for these compounds to identify their properties in air and water (e.g., stability in the atmosphere, photodegradation in water, environmental partitioning behavior) that enhance chemical persistence and ultimate accumulation in biota.

Sturgis Hooper Professor of Geology Professor of Environmental Science and Engineering Director of the Harvard University Center for the Environment; Director of the Science, Technology, and Public Policy Program, HKS
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.
Vertical velocities in the ocean are prohibitively slow to measure directly, so physical oceanographers have been attempting to estimate them by other means for several decades. There is strong motivation to do so; upwelling fuels marine life by bringing nutrient-rich water into the sunlit surface layer. Upwelling also affects the atmosphere by cooling the surface, which affects wind and clouds. The surprising abundance and diversity of life—from corals to fish to seabirds—around equatorial islands, has been...
Talk Title: From Microbial to Global: What Mercury Stable Isotopes Can Tell us about Mercury Bioaccumulation
Abstract: Mercury (Hg) stable isotopes have become a standard approach to study Hg sources and processes in the environment. Despite the power of these tools, applying Hg isotopes to understand source to receptor relationships can be difficult due to the myriad of...

Title: Influence of fluid-assisted healing on fault permeability structure
Abstract: Micro-cracks in fault damage zones can heal through diffusive mass transfer controlled by temperature and pressure. The diffusion of pore fluid pressure in fault damage zones...
Alexis Berg (firstname.lastname@example.org) is a Research Associate in Prof. Kaighin McColl's group. He is an Earth System scientist whose research interests focus on land-climate interactions, land surface hydrology and global ecosystems. His research relies primarily on the analysis of climate model simulations and global observational datasets. On-going research focuses on understanding the coupled responses of the continental water cycle, land ecosystems and climate to greenhouse warming.
Alexis Berg obtained his PhD in 2011 from Pierre and Marie Curie University (Paris, France), working at the Institute Pierre Simon Laplace (IPSL).

Dr. Anna M. Michalak is a faculty member in the Department of Global Ecology of the Carnegie Institution for Science and a professor in the Department of Earth System Science at Stanford University. She studies the cycling and emissions of greenhouse gases at urban to global scales – scales directly relevant to informing climate and policy – primarily through the use of atmospheric observations. She also explores climate change impacts on freshwater and coastal water quality via influences on nutrient delivery to, and on conditions within, water bodies. Her approach is focused on the...
