Professor Tushnet, who graduated from Harvard College and Yale Law School and served as a law clerk to Justice Thurgood Marshall, specializes in constitutional law and theory, including comparative constitutional law. His research includes studies examining (skeptically) the practice of judicial review in the United States and around the world. He also writes in the area of legal and particularly constitutional history, with works on the development of civil rights law in the United States and (currently) a long-term project on the history of the Supreme Court in the 1930s.
