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. Before graduating with a MSc in science and executive engineering and a minor in geostatistics and applied probabilities from Mines ParisTech (Paris, France), 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. Most recently, 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 CV should generally take a backseat to asking really interesting questions. Leyatt is now a Ph.D. student in security studies whose research interests center on issues of nuclear strategy, arms control and diplomatic history.
Maya Buchanan
Washington University-St Louis, 2006; Johns Hopkins University, 2008
Economics/Environmental Studies, B.A.; Environmental Engineering and Geography, M.S.
Salt Lake City, UT
Maya grew up in Salt Lake City, Utah. She started her career developing integrated water resources projects for the World Conservation Union, the United Nations and CDM engineering in Jordan. As a Fulbright fellow, she modeled water scarcity amidst climate change. Maya later worked on federal sustainability and Earth science projects for the Architect of the Capitol, Department of Energy, and NASA. Most recently, she worked for the White House Subcommittee on Global Change Research on developing the U.S. Government’s priorities in advancing climate science and informing decision makers. Maya’s research interests lie in optimizing resilience to climate change impacts, particularly to sea level rise in the face of multiple economic and social stressors.
Christopher Crawford
University of Michigan-Ann Arbor, 2012
Ecology and Evolutionary Biology, B.S.
East Lansing, Michigan
Chris comes to Princeton after three and a half delightful years working at Sustainable Conservation, an environmental nonprofit in San Francisco. He worked on Sustainable Conservation’s PlantRight initiative, collaborating with plant scientists, environmental groups and the horticultural industry to stop the sale of invasive plants in California. Along with PlantRight, he worked to provide incentives for riparian restoration in California’s Central Valley, leading a cost-benefit analysis to help inform restoration along the Mokelumne River. A Michigan native, Chris attended the University of Michigan in Ann Arbor, graduating in 2012 after studying ecology & evolutionary biology and physics. Among other things, he enjoys riding his bicycle, taking pictures of clouds, cooking vegetarian stir fries and listening to Swedish music. An avid traveler, he spent much of the summer finding environmental inspiration while road-tripping coast to coast. After graduating, Chris hopes to collaboratively improve the implementation of biodiversity conservation in developing countries.

Jamie Gruffydd-Jones
Oxford University, 2006; Oxford University, 2008
Philosophy/Psychology, B.A.; African Studies, MSc
Bath, United Kingdom
Jamie’s research focuses on the impact of international pressure on public opinion in the target country, particularly in relation to China, and the conditions under which it may have counterproductive effects. His thesis examines further how authoritarian regimes deal with information about international pressure domestically. He is also interested in how international actions affect domestic attitudes and behaviors and novel methodologies of measuring nationalism and its impacts. Jamie’s forthcoming research project looks at the impact of Western human rights violations on the behavior of authoritarian regimes.
Yixin Guo
Peking University, 2014
Atmospheric Sciences, B.S.
Beijing, China
Yixin joins the STEP family after finishing undergraduate study in atmospheric and oceanic sciences in Peking University, China. Back then, she had intensive training in physics, programming and maths and particularly explored the summertime long-range transpacific transport of ozone. The voluntary experience for the Nature Conservancy Beijing Office in her senior year further cultivated an interest in science policy and raised concerns about China's climate and air pollution policy. At Princeton, several courses and seminars make Yixin interested in agriculture, i.e. agricultural pollution from fertilizer and manure, food security and rural development. She looks forward to helping a transition to sustainable practices in the developing world.
