Ilya Shapiro is the director of the Robert A. Levy Center for Constitutional Studies at the Cato Institute. Before joining Cato, he was a special assistant/adviser to the Multi-National Force in Iraq on rule-of-law issues and practiced at Patton Boggs and Cleary Gottlieb.

Shapiro is the co-author of Religious Liberties for Corporations? Hobby Lobby, the Affordable Care Act, and the Constitution (2014), and editor of 11 volumes of the Cato Supreme Court Review (2008-18). He has contributed to a variety of academic, popular, and professional publications, including the Wall Street Journal, Harvard Journal of Law & Public Policy, Washington Post, Los Angeles Times, USA Today, National Review, and New York Times Online. He also regularly provides commentary for various media outlets, including CNN, Fox News, ABC, CBS, NBC, Univision and Telemundo, the Colbert Report, PBS NewsHour, and NPR.

Shapiro has testified before Congress and state legislatures and has filed more than 300 amicus curiae “friend of the court” briefs in the Supreme Court, including one that The Green Bag selected for its “Exemplary Legal Writing” collection. He lectures regularly on behalf of the Federalist Society, was an inaugural Washington Fellow at the National Review Institute and a Lincoln Fellow at the Claremont Institute, and has been an adjunct professor at the George Washington University Law School. He is also the chairman of the board of advisors of the Mississippi Justice Institute, and a member of the Virginia Advisory Committee to the U.S. Commission on Civil Rights. In 2015, National Law Journal named him to its 40 under 40 list of “rising stars.”

Before entering private practice, Shapiro clerked for Judge E. Grady Jolly of the U.S. Court of Appeals for the Fifth Circuit. He holds an AB from Princeton University, an MSc from the London School of Economics, and a JD from the University of Chicago Law School (where he became a Tony Patiño Fellow).
