Biographical Profiles of Current Ph.D. Graduate Students

Hélène Benveniste
Ecole Nationale Superieure des Mines de Paris, 2012
Science and Executive Engineering, Master
Rennes, Brittany, France
Hélène is a fourth year Ph.D. student in the Program in Science, Technology and Environmental Policy (STEP) at the Woodrow Wilson School. In her dissertation, she focuses on interactions between damages from climate change, international migration and inequality, using Integrated Assessment Models and a scenarios-based approach. She is also interested in International Environmental Agreements design, and in communication between science and policymaking on climate change. Hélène graduated in 2012 with a MSc in science and executive engineering from Mines ParisTech, France. For her master’s thesis at the National Center for Atmospheric Research in Boulder, Colorado, 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. During the Paris Agreement year, she worked as research scientist and project manager of a scientific advisory group to the French climate negotiation team, focusing on assessing countries’ Nationally Determined Contributions. When not obsessing over climate change, Hélène can be found in the local movie theater or hiking in the nearest national parks.
Christopher Crawford
University of Michigan-Ann Arbor, 2012
Ecology and Evolutionary Biology, B.S.
East Lansing, Michigan
Chris is a fourth-year Ph.D. student in the environmental policy program, studying biodiversity conservation through the lens of agricultural land use change. As demographic, technological, and environmental forces change the spatial distribution of global agriculture, Chris is particularly interested in regions where agriculture is being abandoned or repurposed, and the environmental trade-offs these changes represent. Where do these transitions present opportunities for habitat regeneration in former agricultural fields, and how might policy be designed to harness these opportunities and encourage conservation? Chris aims to answer these questions by leveraging global datasets and geospatial analysis tools while drawing on the fields of ecology, environmental science, and economics. Prior to graduate school, Chris worked at the nonprofit Sustainable Conservation in San Francisco, working to encourage river restoration in California’s Central Valley and prevent the use of invasive plants in gardening and landscaping. Chris graduated from the University of Michigan in 2012, and likes riding his bicycle, taking pictures of clouds, and listening to Swedish music.
