Professor William C. Banks is recognized internationally as an expert in constitutional law, national security law, and counterterrorism. Since 1987, when the Federation of American Scientists asked him to provide a legal perspective on first use of nuclear weapons, Banks has helped set the parameters for the relatively new field of national security law.
Banks co-wrote the definitive text in the field. National Security Law was first published in 1990 and is now in its fourth edition. Banks and his co-authors published Counterterrorism Law in 2007 to help define the emerging field of counterterrorism law. Banks is also the author of numerous other books, book chapters and articles including Constitutional Law: Structure and Rights in Our Federal System, 5th Ed., "The Death of FISA," "Legal Sanctuaries and Predator Strikes in the War on Terror," and "Targeted Killing and Assassination: The U.S. Legal Framework."
In addition to teaching United States law subjects, Professor Banks lectures extensively on these and other national security and constitutional law-related topics and on comparative legal systems throughout the United States and Canada, as well as in South and Central America, the Middle East, the Caribbean, Asia, Africa, and Europe. Banks' current research interests include domestic and international terrorism, emergency powers, war powers, emergency preparedness and response, civil/military relations, and appropriations powers.
