Don Casler

Welcome! I am an assistant professor at the University of Illinois at Urbana-Champaign. During the 2022-23 academic year, I was a postdoctoral research associate at Brown University's Watson Institute for International and Public Affairs. Previously, I was a Hans J. Morgenthau Fellow at the University of Notre Dame's International Security Center. I received my Ph.D. in political science from Columbia University in 2022.


I research topics at the nexus of international security and international political economy, with a particular focus on political psychology, organizational theory, and the use of historical and experimental methods. My book project uses an organizational lens to examine when and why foreign policy decision makers express concern for their state's credibility and reputation, as well as how these concerns shape bureaucrats' policy advocacy regarding the use of force during crises. This research has been funded by both the Smith Richardson and Charles Koch Foundations. It also received the 2023 Kenneth N. Waltz Dissertation Award from the American Political Science Association and the 2023 Alexander George Award from the International Studies Association.


My other research has been published or is forthcoming in International Studies Quarterly, Journal of Conflict Resolution, Journal of Politics, Security Studies, and World Politics. My ongoing projects can be found under the "Research" tab.
