Ivan Sascha Sheehan specializes in the intersection of global terrorism, counterterrorism, and international conflict management. He came to the University of Baltimore after serving on the graduate faculty at the University of Massachusetts Boston in the John W. McCormack School of Policy Studies (Graduate Programs in Dispute Resolution). A frequent speaker on U.S. counterterrorism efforts in the War on Terrorism, Sheehan has addressed diverse audiences from academic forums in Europe and at Harvard Law School to policymakers on Capitol Hill. His research, based on terrorism incident data, examines the impact of pre-emptive force on terrorist activity and the implications for U.S. foreign policy and international human security.

Sheehan studied post-conflict stabilization and reconstruction in war-torn societies through the Peace Operations Policy Program at George Mason University’s School of Public Policy and the Center for International Development and Conflict Management at the University of Maryland. He was trained in mediation at the Harvard Mediation Program and has served as a court-appointed mediator.

Sheehan previously taught in the International Studies Department at Bentley College and at Tufts University. He continues to serve on the visiting faculty at the Institute for Conflict Analysis and Resolution. His first book, When Terrorism and Counterterrorism Clash: The War on Terror and the Transformation of Terrorist Activity , was published in December 2007.
