Professor Ohlin specializes in international law and all aspects of criminal law, including domestic, comparative, and international criminal law. His latest work concentrates on the legal implications of remotely piloted drone strikes, and he is a co-editor of a collected volume entitled Targeted Killings: Law and Morality in an Asymmetrical World, forthcoming from Oxford University Press in 2012.
He also 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, the Journal of International Criminal Justice, the Cornell Law Review, the Chicago Journal of International Law, as well as several edited volumes published by Oxford University Press.
Professor Ohlin's current research also 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. His work has been cited by judges and litigants at several international tribunals, including the ICTY, the ICC, and the ECCC. He is also a member of an international working group, centered in The Hague, that is developing a codification of general rules and principles of international criminal procedure.
Professor Ohlin has consulted for foreign governments and law firms on a wide range of issues, including human rights, white collar criminal defense and litigation, criminal antitrust, and appellate litigation.
