I am a postdoctoral research fellow at the Belfer Center for Science and International Affairs at the Harvard Kennedy School. I study crisis escalation, coercive diplomacy, and nuclear security, with a regional focus on China, the Korean peninsula, and the Asia-Pacific. My book project, Playing with Fire: Provocation, Crisis Escalation, and Inadvertent War, explains the escalatory dangers of provocation in international crises.

​I hold a Ph.D. in Political Science from the University of Pennsylvania, M.A.s in Political Science from Columbia University and in International Relations from Seoul National University, and a B.Sc. in Government and Economics from the London School of Economics. I have also held fellowships at George Washington University and Stanford University. ​
