Hélène Benveniste
Ecole Nationale Superieure des Mines de Paris, 2012
Science and Executive Engineering, Master
Rennes, Brittany, France
Born and raised in Brittany, France, Hélène has developed a passion for interdisciplinary approaches to solve the climate change challenge. As part of her Ph.D. studies in the Program in Science, Technology and Environmental Policy, she focuses on quantifying economic impacts of climate change in terms of migrations and conflict risks, using integrated assessment models. She is also interested in international environmental agreements design, as well as using behavioral science to improve communication between scientists and policy makers on climate change. Before graduating with a MSc in science and executive engineering and a minor in geostatistics and applied probabilities from Mines ParisTech, she was a research fellow at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado where she developed a statistical tool for scoring extreme climate events forecasts. She then started her career as deputy attaché for energy at the French Embassy in Germany, and as such followed the development and implementation of the German energy transition. Right before joining the Woodrow Wilson School, Hélène worked as a research engineer and project manager on an expertise mission for the French government; the mission, linked to the United Nations Framework Convention on Climate Change 21st Conference of the Parties (COP21), aimed at assessing the Intended Nationally Determined Contributions (INDC) presented by countries ahead of COP21, and used as a new tool for climate negotiations.
Leyatt Betre
Massachusetts Institute of Technology, 2016
Physics/Political Science, B.S.
Frisco, Texas
As a first-generation American born to Ethiopian parents, Leyatt had a small town Texas upbringing often punctuated by encounters with the wider world. While she cannot claim any encounters of the third kind, she picked up an early love of astronomy and the slightly less wide world of international politics. Leyatt went on to study physics and political science at MIT, where she sought to forge some semblance of academic and personal coherence out of her dual interests. After researching the early chemical evolution of the Milky Way, the spatial distribution of dark matter halos, the drivers of nuclear proliferation, and the role of arms control in shaping U.S. force posture, she concluded that the coherence of one’s C.V. should generally take a backseat to asking interesting questions. Leyatt is a Ph.D. student in security studies whose research interests center on issues of nuclear strategy, arms control and diplomatic history.
