Jeffrey T. Checkel  – Full-time Professor, Department of Political and Social Sciences

Jeffrey T. Checkel joined the Department of Political and Social Sciences in January 2020, as Chair in International Politics, moving from Simon Fraser University in Vancouver, where he held the Simons Chair in International Law and Human Security. He had previously taught at the University of Pittsburgh and the University of Oslo.After a first degree from Cornell University in applied physics, Checkel received a PhD in political science from the Massachusetts Institute of Technology. A consistent theme in his scholarship has been to bridge divides of discipline, epistemology, and subfield. After a start in Sovietology and arms control, Checkel turned to the study of institutions and norms; to European politics and identity; to transnationalism, civil wars and political violence; and – most recently – to international institutions and the populist backlash against them.Checkel’s research interests include international relations theory (domestic-international linkages, international institutions, constructivism, governance), conflict studies (civil war), European integration (Europeanization, identity) and qualitative methods (process tracing, bridging positivist-interpretive techniques).He has published broadly on these topics, including four books from Cambridge University Press and one volume from Yale University Press. At EUI, he offers seminars on international-relations theory; civil wars; the liberal order and identity politics; international institutions; qualitative methods; and philosophies of social science.

Research interests: Conflict and Peace, International Relations, Identity, Internal Institutions.
