Don Casler is a Ph.D. candidate in political science at Columbia University and studies topics at the intersection of international security and international political economy. During academic year 2021-22, he has been appointed as a Teaching Scholar through Columbia's Graduate School of Arts & Sciences and a Hans J. Morgenthau Fellow at the University of Notre Dame's International Security Center.

Mr. Casler's research interests include foreign policy decision making, political psychology, public opinion, and historical political economy. His dissertation project, “Credible To Whom? The Organizational Politics of Credibility in International Politics” explores the bureaucratic sources of national security policymakers’ concern for the credibility of their state's commitments, and in turn, how these concerns shape policy advocacy, deliberation, and decision making regarding the use of force during crises.

He received a B.A. from Dartmouth College in June 2014, where he graduated cum laude and was awarded high honors for his senior thesis, Brasher With The Bomb? The Effects of Nuclear Weapons on Interstate Aggression.
