Before his appointment to the bench, Bibas was a Professor of Law and Criminology at the University of Pennsylvania and Director of Penn’s Supreme Court Clinic.  He holds degrees from Columbia, Oxford, and Yale.  Bibas studies the powers and incentives that shape how prosecutors, defense counsel, defendants, and judges behave in the real world of guilty pleas.
