Welcome! My name is Chagai Weiss. I am a postdoctoral fellow at the Conflict and Polarization Lab at Stanford University. I defended my dissertation at the Political Science Department at the University of Wisconsin-Madison in summer 2022, after spending two years as a Middle East Initiative predoctoral fellow at the Harvard Kennedy School.

My core interest is in examining how institutions and the people within them shape intergroup relations in divided societies. I am also working on several projects examining the effects of scalable interventions for prejudice reduction, the electoral effects of conflict, the institutional origins of partisan polarization, and experimental methods. My research has been published or is forthcoming in Cambridge University Press, the Proceedings of the National Academy of Sciences, the American Journal of Political Science, Comparative Political Studies, and other journals.

I co-coordinate the Intergroup Relations Workshop — a virtual workshop which meets periodically to provide feedback on political science and social psychology research relating to intergroup relations.
