I am an environmental scientist who investigates the drivers and impacts of agricultural change, with a particular focus on Africa. I conduct my research using new Earth Observation technologies and a range of modeling techniques, and work within inter-disciplinary projects that involve economists, agronomists, human geographers, decision scientists, hydrologists, climatologists, and computer scientists. I hold a BA in English from Georgetown University, an MPhil in Conservation Biology from the University of Cape Town, and a PhD in Environmental Science from the University of Virginia. After receiving my PhD degree in 2008 and before joining Clark, I worked as a research scientist in Princeton University’s School of Public and International Affairs and Department of Civil and Environmental Engineering. Prior to my academic career, I spent nearly 9 years working in protected area management and environmental consulting in Southern Africa.
