My research falls under the broad umbrella of international relations and political psychology, seeking to understand the behavioral micro-foundations underpinning political violence, war, and conflict across and within societies. My current projects explore five key themes: 1) psychological causes and consequences of political violence, 2) strategic and psychological dynamics of terrorism, 3) group processes in foreign policy decision-making, 4) patterns of conflict in Israel-Palestine, and 5) the psychology of intergroup contention and cooperation.
