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) the strategic use of terrorism globally and its emotional consequences for public opinion, 2) the short- and long-term psychological consequences of political violence, 3) group processes in foreign policy decision-making, 4) patterns of conflict and contention in Israel-Palestine, and 5) the psychology of intergroup contention and cooperation.
