about me

I am a development microeconomist, with interests in political economy, urban economics, and environmental economics. 

My research studies how foreign investors navigate conflict and corruption; the politics of international finance; political communication in pandemics; the environmental and political consequences of natural resource wealth; urbanization in emerging countries; and climate change adaptation. My work has appeared in top academic journals, including the American Economic Review (AER), the American Economic Journal - Policy (AEJ), the Economic Journal (EJ), and the Proceedings of the National Academy of Sciences (PNAS). 

I am currently an Economist at the World Bank in the Office of the Chief Economist for South Asia (SARCE), as well as a visiting scholar at Princeton University. At the Bank, I have worked on climate adaptation, gender, and labor markets. 

Previously, I was a Postdoctoral Associate in the Empirical Studies of Conflict research group and Lecturer at the School of Public and International Affairs, Princeton University.

I hold a PhD in Applied Economics from the Wharton School of Business, University of Pennsylvania, and an MPA/ID from the Harvard Kennedy School. I have conducted field research in Uganda, Nigeria, India, and Myanmar.
