A graduate of UCLA School of Law, Professor Robinson, is one of the world’s leading scholars on criminal law. He joined the Penn Law faculty in Spring 2003, coming from Northwestern. Prior to that, Professor Robinson served as a federal prosecutor, as counsel for the U.S. Senate Subcommittee on Criminal Laws and Procedures, and as one of the original commissioners of the U.S. Sentencing Commission, where he was the lone dissenter to promulgation of what are the current federal sentencing guidelines. Among his dozen books are the standard lawyer’s reference book on criminal law defenses, an internationally-known Oxford monograph on criminal law theory, a highly-regarded criminal law treatise, a popular innovative case studies course book, and a ground-breaking empirical study of the conflict between criminal law rules and lay intuitions of justice.
