Nadja Drabon

Assistant Professor of Earth and Planetary Sciences
My research focuses on the habitability of the early Earth and how it was affected by crustal processes and changing surface environments. The study of the early Earth requires a clear understanding of present-day sedimentary processes as well as an appreciation of the non-uniformitarian character of the early Earth. My research integrates multidisciplinary approaches by applying stratigraphic, provenance and geochemical analyses paired with detailed knowledge of complex geology at outcrop- to basin-scale. Specifically, my contributions to the field focus on: (1) Furthering our understanding of the formation of crust during the Hadean and Archean, (2) evaluating processes of early life recorded in the rock record and studying the influence of impact-related environmental perturbations on the biosphere, and (3) characterizing the poorly understood tectonic processes in the Archean.

Rebecca Fischer

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.

Peter Huybers

Professor of Earth and Planetary Sciences
Professor of Environmental Science and Engineering

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.

Huybers received a B.S. from the United States Military Academy at West Point in 1996 and a Ph.D. from the Massachusetts Institute of Technology in 2004.

Frank Keutsch

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.
