I am an Associate Professor and the Giancarlo Elia Valori Chair in the Study of Peace and Regional Cooperation in the Department of International Relations at the Hebrew University of Jerusalem. He received his Ph.D. from the Ohio State University and had taught at the University of Illinois-Chicago. His research agenda touches on the sources, design, and effects of international organizations and agreements. His book, Regional Economic Institutions and Conflict Mitigation: Design, Implementation, and the Promise of Peace (2012), explores the relationships between variation in regional economic organizations (REOs) and regional security. In other projects he explores security cooperation within REOs and overlapping regionalism as well as the politics of investment treaty ratification and renegotiation. He published peer-reviewed articles on these and other topics in such journals as International Organization, International Studies Quarterly, the Journal of Conflict Resolution, and the Review of International Organizations.
