Ohlin, Jens David

Cornell Faculty Member


Jens Ohlin earned a Ph.D. in philosophy from Columbia University and a J.D. from Columbia Law School, where he also served as an associate-in-law for two years. His research and teaching interests are focused on criminal law theory, public international law, and international criminal law. He is the author, with George Fletcher, of Defending Humanity: When Force is Justified and Why (Oxford University Press, 2008), which offers a new account of international self-defense through a comparative analysis of the rules of self-defense in criminal law. His scholarly work has appeared in the Columbia Law Review, the Harvard International Law Journal, the American Journal of International Law, the Journal of Criminal Law & Criminology, and the Journal of International Criminal Justice, and he has forthcoming work in the Cornell Law Review, the Chicago Journal of International Law, and edited volumes published by Oxford University Press. His current research focuses on the normative application of criminal law concepts in international criminal law, especially with regard to genocide, torture, joint criminal enterprise and co-perpetration, as well as the philosophical foundations of collective criminal action. Prof. Ohlin is also a member of an international working group developing general rules and principles of international criminal procedure.
