Previously, he served as the Marianne D. Short and Ray Skowyra Sesquicentennial Assistant Professor of Law at Boston College Law School, where he was a winner of the Innovation in Pedagogy Award, and as a fellow at Columbia Law School.

His scholarship is informed by a unique combination of high-level legal practice at both U.S. federal criminal and international criminal legal institutions.

During this time, he also taught International and Transnational Criminal Law as an Adjunct Professor at Georgetown University Law Center. He also held positions at two major international criminal courts in The Hague: as a Visiting Professional in the Presidency of the International Criminal Court and as an Associate Legal Officer at the U.N. International Criminal Tribunal for the former Yugoslavia, where he served in Chambers on Prosecutor v. Radovan Karadžić, one of the landmark trials in the Tribunal’s history. Additional international experiences include service as a Visiting Scholar at Seoul National University in South Korea; study at the Cornell Summer Institute in International & Comparative Law at Université Paris I Panthéon-Sorbonne; representation of the Robert F. Kennedy Center for Human Rights before the OAS Inter-American Commission on Human Rights; and human rights research on a mission to Colombia co-sponsored by Senator Edward M. Kennedy. He has also been a Senior Fellow and Interim Attorney-Editor at the American Society of International Law in Washington, D.C., and a law clerk for the Honorable Carolyn Dineen King of the U.S. Court of Appeals for the Fifth Circuit.
