I am an Assistant Professor of Economics at the National School of Development, Peking University. My research as a development economist examines how people in low-income settings make decisions under poverty, and why development programs often fall short in practice. I combine field experiments, original data, and close engagement with real-world programs, primarily in Sub-Saharan Africa.

My work studies health, service delivery, and household responses to shocks, and more recently the impacts of artificial intelligence on labor markets. Across contexts, I focus on how individual behavior and organizational design jointly shape development outcomes.
