Matthew C. Waxman

Matthew C. Waxman, a distinguished scholar of national security law, cybersecurity, and constitutional war powers, is the Liviu Librescu Professor of Law and the faculty chair of the National Security Law Program at Columbia Law School, which draws on faculty experience and expertise in government to address policy and real-world challenges.

Waxman has taught classes on cybersecurity, constitutional war powers, surveillance and privacy, and the law of the sea.

He has served in senior positions at the State Department, Department of Defense, and the National Security Council, and he is a member of the Council on Foreign Relations. He has testified on the question of cyberattacks as acts of war before the Senate Armed Services Committee.

Waxman is co-chair of the interdisciplinary Center for Cybersecurity, which is focused on developing capacity to keep data private and secure, at the Columbia Data Science Institute.

Lawyers argue endlessly about the president’s authority to use force, while constitutionally unconstrained threats—to coerce or deter enemies and to reassure allies—remain one of the most important ways in which the United States government actually wields its military might, and have enormous consequences for sustaining peace or provoking war.
