My research centers on issues of international security. I study the effects of psychology and biology on international conflict. My work examines how collective emotions shape national identity, how gender and suffrage interact to affect war and peace, how public opinion affects the evolution of norms and how rhetorical justifications for territory relate to the use of force.


My book The Consequences of Humiliation: Anger and Status in World Politics  has been published at Cornell University Press. 


I teach courses on psychology in international relations, nuclear weapons, territory and conflict and explanations for war and peace.
