Orin Kerr is one of the country’s foremost scholars of the Fourth Amendment and criminal procedure. He helped found the field of computer crime law, which studies how traditional legal doctrines must adapt to digital crime and digital evidence. Kerr has authored more than seventy law review articles, over half of which have been cited in judicial opinions (including eight different articles that have been cited in U.S. Supreme Court opinions). He is regularly listed as among the most cited and most influential law professors in the United States. In addition to writing law review articles, Kerr has authored popular casebooks, co-authored the leading criminal procedure treatise, and published countless blog posts. These days he also wastes a lot of time on Twitter.

Kerr has briefed and argued cases in the United States Supreme Court and three federal circuits. He has testified six times before Congressional committees. From 2013-2019, Kerr served on the Advisory Committee for the Federal Rules of Criminal Procedure by appointment of Chief Justice Roberts. In 2015, the Chief Justice appointed him to serve on the Judicial Conference’s committee to review the Criminal Justice Act. Before attending law school, Kerr earned undergraduate and graduate degrees in mechanical engineering. He has served as a law clerk for Judge Leonard I. Garth of the U.S. Court of Appeals for the Third Circuit and Justice Anthony M. Kennedy of the United States Supreme Court. He has also served as a trial attorney in the Computer Crime and Intellectual Property Section at the U.S. Department of Justice and a Special Assistant U.S. Attorney in the Eastern District of Virginia.

Prior to joining the Berkeley Law faculty, Kerr was a professor at the George Washington University Law School and later at the University of Southern California Gould School of Law. He also has been a visiting
professor at the University of Pennsylvania and the University of Chicago.
