I am a Professor and the Giancarlo Elia Valori Chair in the Study of Peace and Regional Cooperation in and the Department Chair of the Department of International Relations at the Hebrew University of Jerusalem. I have received his Ph.D. from the Ohio State University and had taught at the University of Illinois-Chicago. My research agenda touches on the sources, design, and effects of international organizations and agreements. My 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 I explore security cooperation within REOs and overlapping regionalism as well as the politics of investment treaty ratification and renegotiation. I have 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.
