about me
I am an economist studying political economy, firms, financial markets, the environment, and structural transformation in developing economies. My work examines how institutions, social norms, conflict, climate change, and new technologies shape economic behavior and development. I use applied microeconomic methods, combining large administrative and spatial datasets with theory-driven causal inference, field research, and experiments.
My work has appeared in the American Economic Review, American Economic Journal: Economic Policy, Economic Journal, and Proceedings of the National Academy of Sciences, among other outlets.
I am an Economist at the World Bank in the Office of the Chief Economist for South Asia, and was previously 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, Pakistan, Bangladesh, and Myanmar.
