I am a 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. 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.
