Gas-phase kinetics of free radicals; catalytic processes in the atmosphere controlling global change of ozone; high-altitude experiments from balloons and aircraft; development of laser systems for stratospheric and tropospheric studies; development of high-altitude, long-duration unmanned aircraft for studies of global change.
Assistant Professor of Earth and Planetary Sciences
Accretion, core formation, and composition of the deep interiors of Earth and other terrestrial planets. She combines high-pressure, high-temperature mineral physics experiments with planetary-scale modeling.
Professor of Environmental Science and Policy Teresa and John Heinz Professor of Environmental Policy
John P. Holdren is the Teresa and John Heinz Professor of Environmental Policy at the Kennedy School of Government; Co-Director of the Program on Science, Technology, and Public Policy in the Kennedy School’s Belfer Center for Science and International Affairs; and Professor of Environmental Science and Policy in the Department of Earth and Planetary Sciences at Harvard University. He is also Senior Advisor to the Director at the independent, nonprofit Woods Hole Research Center. From January 2009 to January 2017, he was President Obama’s Science Advisor and the Senate confirmed Director of the White House Office of Science and Technology Policy (OSTP), becoming the longest-serving Science Advisor to the President in the history of the position (dating back to World War 2). His responsibilities in that role included advising the President on all S&T issues bearing on the President’s agenda (including economic competitiveness and job creation, biomedicine and public health, energy and climate change, the oceans and the Arctic, the Nation’s space program, and national and homeland security); coordinating R&D strategy and budgets across the Executive Branch departments and agencies; overseeing interagency S&T programs, including the U.S. Global Change Research Program; developing initiatives in STEM education; advancing scientific integrity and openness in government; and representing the U.S. government in interactions with the U.S. and global science and engineering communities.
Professor of Earth and Planetary Sciences and Environmental Science and Engineering; Co-Director, Harvard University Center for the Environment
Peter Huybers is a Professor of Earth and Planetary Sciences at Harvard University whose research interests lie in developing a better understanding of the climate system and its implications for society. On-going research involves interactions between volcanism and glaciation, trends and predictability of extreme temperatures, and implication of climate change for food production.
Isotope geochemistry and cosmochemistry; the formation and early differentiation of the terrestrial planets; the chemical evolution of Earth's crust-mantle system; Earth systems evolution and environmental geochemistry.
Professor of the Natural Sciences and co-Director of Graduate Studies
Isotope geochemistry and historical geobiology. Re-animating ancient ecosystems and ocean chemistry using stable isotope systems, chemical speciation techniques, modern microbial experiments (for calibration) and theoretical considerations.
