Courses Recently Taught


Professor Walen has recently taught courses in criminal law, homeland security and counterterrorism law, the philosophy of rights, and constitutional law. He holds a joint appointment in the School of Law, and the Philosophy Department and the Program in Criminal Justice on the New Brunswick campus. Prior to joining the faculty at Rutgers, he was a research scholar at the Institute for Philosophy and Public Policy at the University of Maryland. He has also taught at the University of Heidelberg (Germany), Aachen University (Germany), the University of Baltimore, Harvard University, and Lafayette College.

Professor Walen earned his B.A. summa cum laude at the University of Maryand, College Park, in 1987. He then won a National Melon Fellowship in the Humanities, and earned a Ph.D. in Philosophy at the University of Pittsburgh in 1993. He earned his J.D. from Harvard in 1998. He was a fellow at the Center for Ethics and the Professions at Harvard University from 1996-97. He clerked for District Court Judge Nancy Gertner (1998-99), and worked for the D.C. office of what was then known at the law firm Mayer, Brown and Platt (1999-2000).

His academic work has ranged over topics in moral philosophy, criminal law, constitutional law, and national security law. His current projects can be grouped under two headings: (1) a liberal account of when detention is justifiable, and (2) an examination of rights, intentions and permissibility. Both of these are book projects. The first is now under contract at Oxford University Press, under the title: "Detention in a Liberal State."
