Don Casler

Welcome! I am a Ph.D. candidate in the political science department at Columbia University. 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 dissertation 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. My other ongoing projects can be found under the "Research" tab.
