Rebecca Crootof is an Assistant Professor of Law. Dr. Crootof's primary areas of research include technology law, international law, and torts; her written work explores questions stemming from the iterative relationship between law and technology, often in light of social changes sparked by increasingly autonomous systems, artificial intelligence, cyberspace, robotics, and the Internet of Things. She is interested in the various ways both domestic and international legal regimes respond to and shape technological development, particularly in the armed conflict context.

Dr. Crootof earned a B.A. cum laude in English with a minor in Mathematics at Pomona College; a J.D. at Yale Law School; and a PhD at Yale Law School, where she graduated in the first class of PhDs in law awarded in the United States. Her dissertation, Keeping Pace: New Technology and the Evolution of International Law, discusses how technology fosters change in the international legal order, both by creating a need for new regulations and by altering how sources of international governance develop and interact. She has published with the Cornell Law Review, the Duke Law Review, the Pennsylvania Law Review, the Harvard National Security Journal, the Yale Journal of International Law, and the Yale Law Journal; and written for Slate, Lawfare, and Just Security.

Dr. Crootof served as a law clerk for the late Judge Mark R. Kravitz of the U.S. District Court for the District of Connecticut and for Judge John M. Walker, Jr. of the U.S. Court of Appeals for the Second Circuit. She consults for the Institute for Defense Analyses and is a member of the New York Bar, the Equal Rights Center's Board of Directors, the Center for New American Security's Task Force on Artificial Intelligence and National Security, and the Permanent Mission of the Principality of Liechtenstein to the United Nations' Council of Advisers on the Application of the Rome Statute to Cyberwarfare.

She enjoys skiing, hiking, and reading science fiction "for work."
