My name is Hohyun Yoon. I am a PhD candidate in Political Science at the University of Wisconsin-Madison. I specialize in International Relations with a focus on leader psychology and signaling. My dissertation investigates how leaders’ public expressions of anger during foreign policy crises shape bargaining dynamics, using both observational and experimental data. I am also broadly interested in international security, cooperation, and alliances. My work has appeared in the Journal of Conflict Resolution.
