Soomin Oh is a PhD candidate in Political Science specializing in political economy. Her research primarily focuses on explaining subnational variations in access to water, sanitation and health services in the developing world. In her dissertation, she proposes a spatial framework to explain the local variations in the patterns of public goods provision and tests the framework using fine-grain survey data and quasi-natural experiments of Indonesia and Cameroon. She argues that local public goods have spatial externalities defined by the extent of their catchment area, and elites allocate strategically by targeting catchment areas that are rich in core voters and have greater returns to investment. Further, as a member of DevLab@Duke, she collaborates with international donors and government agencies in designing policy interventions and the evaluations thereof.
