Alex Weisiger, Ph.D. Columbia University, 2008, studies international politics, focusing in particular on political decisions relating to the use of force. His primary research focus has been on the sources of variation in the duration and severity of interstate wars. In other work, he explores the phenomenon of regional systems of war, the relevance of systemic variables for the democratic peace, and the implications of psychological biases for rationalist explanations for war. He has held fellowships at the Belfer Center for Science and International Affairs and the Olin Institute for Strategic Studies at Harvard University.
His teaching interests include the causes of war and peace, war termination and peacebuilding after conflict, international relations theory, and game theory.
