Dr. Greiff is a conflict analyst specializing in intergroup/interethnic conflicts in the Balkans. His research is focused on the emergence of new violent actors in post-war settings, the political use of cultural matrixes (symbols, discourses, rituals) to mobilize, legitimize and justify violence, and intergroup positioning processes that challenge local moral orders and pose threats to the security and stability of nation states. He teaches conflict resolution at the Elliott School of International Affairs and holds affiliations with the Center for Political Practice and Order, the Center for Narrative and Conflict Resolution, and the Department of Political Science at the University of Pennsylvania. Previously he worked as a visiting researcher at the Department of Government at Georgetown University, the Department for International Relations and International Organizations at the University of Groningen, and the Balkan Institute for Conflict Resolution, Responsability, and Reconciliation at the Sarajevo School of Science and Technology. Next to his academic engagements he serves as the director of f-r-e-e (friendship-respect-education-engagement), an international non-profit organization working in peace and community building in post-conflict environments.
