Theodore Ruger brings fresh insight to the study of some of the oldest questions of American law – namely the theoretical justifications for, and empirical contours of, the application of judicial authority. In exploring these issues, Ruger supplements traditional legal analysis with the methods of other disciplines, including history and political science. His work has appeared in the Harvard Law Review, the Columbia Law Review, the University of Pennsylvania Law Review, the University of Pennsylvania Journal of Constitutional Law, the Northwestern Law Review, and as the centerpiece of a symposium in Perspectives on Politics, a leading peer-reviewed political science journal. In addition to his interests in constitutional law and legislation, Ruger also teaches and writes in the area of health law and pharmaceutical regulation. His current research in that field draws on his broader work on judicial power and constitutionalism, and addresses the manner in which American legal institutions – including the U.S. Supreme Court – have shaped the field of health law over the past two centuries.
