Dr. Gabrielle Dreyfus Chief Scientist

Dr. Gabrielle Dreyfus is the Chief Scientist at IGSD, where she collaborates with leading experts and international partners to conduct research, and craft and advance policies to slow global warming through strategies to control short-lived climate pollutants, improve energy efficiency, and protect carbon sinks. She is also an adjunct lecturer at Georgetown University, where she teaches science policy. Dr. Dreyfus is a member of the Climate & Clean Air Coalition’s Scientific Advisory Panel, the Montreal Protocol’s Technology and Economic Assessment Panel, and chair of the U.S. National Academies’ Committee on Atmospheric Methane Removal: Development of a Research Agenda.

Prior to IGSD, Dr. Dreyfus served as the Deputy Director of the U.S. Department of Energy Office of International Climate and Clean Energy, where she led international initiatives and campaigns to strengthen and scale clean energy policy. She developed expertise in applying science to inform climate, energy, environmental, and international policy in the U.S. Senate, National Oceanic, and Atmospheric Administration (NOAA), and U.S. Department of Energy, through a series of fellowships.

Dr. Dreyfus received a doctorate in Geosciences from Princeton University and Sorbonne Université (formerly the University of Pierre and Marie Curie) for her research reconstructing climate change history from Antarctic ice core records conducted at the Laboratoire des sciences du climat et de l’environnement (LSCE) and Princeton.
