Rebecca Crootof


Rebecca Crootof is the Executive Director of the Information Society Project and a Research Scholar and Lecturer in Law at Yale Law School. 

Crootof's primary areas of expertise are technology law, public international law, and torts. Much of her work considers questions of when law can channel technological developments to promote socially desirable aims; how tort law principles can inform the development of state accountability for practices enabled by new technologies; and the complicated relationships between new weaponry, the law of armed conflict, and international human rights law. She teaches Technology Law at Yale Law School, a course focused on the domestic and international means of regulating legally disruptive technologies. 

Crootof earned a B.A. cum laude in English with a Mathematics minor at Pomona College; a J.D. at Yale Law School; and a PhD at Yale Law School, where she graduated as a member of the first class of PhDs in law awarded in the United States. Crootof's dissertation, Keeping Pace: New Technology and the Evolution of International Law, examines 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.

Crootof has authored pieces on various subjects, including on how the concept of transnational cybertorts can inform the development of the international law of cyberspace, how best to regulate autonomous weapon systems, when customary international law revises treaty law, what factors increase the likelihood that a weapons ban will be successful, and how non-self-executing treaties influence domestic U.S. jurisprudence. She has published with the Cornell Law Review, the Pennsylvania Law Review, the Yale Journal of International Law, the Cardozo Law Review, and the Yale Law Journal; contributed to a NATO book on autonomous weapon systems; and written for Slate, Lawfare, and Just Security.

Crootof served as a law clerk for 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 is a member of the New York Bar and serves on the Board of Directors of the Equal Rights Center. She enjoys skiing, hiking, and reading science fiction "for work."

Crootof hopes someday to be as cool as her sister, who wears a red shirt to go rock climbing.
