Jens David Ohlin became the Allan R. Tessler Dean of Cornell Law School on July 1, 2021. His scholarly work stands at the intersection of four related fields: criminal law, criminal procedure, public international law, and the laws of war. Trained as both a lawyer and a philosopher, his research has tackled questions as diverse as criminal conspiracy and the punishment of collective criminal action, the philosophical foundations of international law, and the role of new technologies in warfare, including cyberwar, remotely piloted drones, and autonomous weapons. Dean Ohlin’s latest research project involves foreign election interference and the use of disinformation as a mode of statecraft by foreign actors. In addition to dozens of scholarly articles, Ohlin is the author of several textbooks and treatises on criminal law and international law.
