Clare Boothe Luce 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.
Fischer received a B.A. in Earth and Planetary Sciences and Integrated Science from Northwestern University in 2009, and a Ph.D. in Geophysical Sciences from the University of Chicago in 2015.
Jerry X. Mitrovica joined Harvard in 2009 as a Professor of Geophysics.His work focuses on the Earth's response to external and internal forcings that have time scales ranging from seconds to billions of years. He has written extensively on topics ranging from the connection of mantle convective flow to the geological record, the rotational stability of the Earth and other terrestrial planets, ice age geodynamics, and the geodetic and geophysical signatures of ice sheet melting in our progressively warming world. Sea-level change has served as the major theme of these studies, with particular emphasis on critical events in ice age climate and on the sea-level fingerprints of modern polar ice sheet collapse.
Mitrovica is the Frank B. Baird, Jr., Professor of Science at Harvard University. He is a former Director of the Earth Systems Evolution Program of the Canadian Institute for Advanced Research and J. Tuzo Wilson Professor in the Department of Physics at the University of Toronto, where he also received his Ph.D. degree. He is the recipient of the Arthur L. Day Medal from the Geological Society of America, the W.S Jardetsky Medal from Columbia University, the A.E.H. Love Medal from the European Geosciences Union and the Rutherford Memorial Medal from the Royal Society of Canada. He is also a Fellow of the American Geophysical Union and the Geological Society of America, as well as a past Fellow of the John Simon Guggenheim Memorial Foundation.
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.

Fisher Professor of Natural History and Professor of Earth and Planetary Sciences
Andy Knoll is the Fisher Professor of Natural History at Harvard University. He received his B.A. in Geology from Lehigh University in 1973 and his Ph.D., also in Geology, from Harvard in 1977.... Read more about Andrew H. Knoll
Daniel Green is Director of the Central Bureau for Astronomical Telegrams and he is involved in research of small bodies of the solar system — particularly comets and meteors, but also minor planets. He collects and archives/publishes data on comets from observers around the world, and these data are published in the International Comet Quarterly (the world’s largest journal devoted solely to comets, which he edits) and posted at the Cometary Science Archive on its computers at EPS. He also directs the acquisition of CCD images of comets on a nightly basis using telescopes in Tibet, and those images are analyzed, measured, and archived; searching for new comets and near-earth asteroids. He is a member of the International Astronomical Union’s 13-member Committee on Small Body Nomenclature, which approves names for comets and minor planets (including trans-Neptunian objects) and their satellites. He is a member of Harvard’s Origins program, with an interest in how observational data of comets can help in the study of their origins and in the origins of the solar system. Green obtained his Ph.D. in physics and astronomy from the University of Durham (U.K.), his thesis focusing on analysis of old astronomical data in the historical literature using modern techniques, to extend our archive of useful data by centuries.

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...
Episodic Plate Motion and Thermal Structure in Subduction Zones Caused by Slab Folding in the Transition Zone
Abstract: Although most present-day subduction zones are in trench retreat, plate reconstructions and geological observations show that individual margins experience episodes of advancing, retreating or stationary trench motion with time-variable subduction rates. However, most laboratory and numerical simulations predict steady plate velocities and sustained trench retreat unless the slab experiences folding in the...
