Joséphine is a 6th year PhD student in Sustainable Development, working across ecosystem ecology and environmental economics. She uses a causal lens to study ecosystem resilience to climate change, and theory to highlight the role of diversity as a factor of resilience in crop ecosystems. She is also exploring methodological questions at the intersection of remote sensing, machine learning and causal inference. In particular, she is working on monitoring flower phenology from space, on modeling plant-pollinator interactions under a changing climate, and on quantifying tree adaptation to temperature extremes using tree ring data.

She graduated from the Ecole Polytechnique with a multidisciplinary bachelor in Science and Engineering, and a masters in Economics and Public Policy. She also holds an MPA in International Development from the London School of Economics. Before joining the PhD program, she worked with the Social Protection Unit and Human Development Network of the World Bank, and then pursued research in development economics, political economy and international trade at the Columbia Business School.
