Orin S. Kerr joined the faculty at USC Gould School of Law in January 2018 as the Frances R. and John J. Duggan Distinguished Professor of Law. From 2001 to 2017, he was a professor at the George Washington University Law School. Kerr has previously been a visiting professor at the University of Chicago and the University of Pennsylvania. An accomplished teacher, Kerr received the outstanding teaching award from the George Washington Law School Class of 2009.

Kerr specializes in criminal procedure and computer crime law, and he has also taught courses in criminal law, evidence, and professional responsibility. He has written more than 60 law review articles, over 40 of which have been cited in judicial opinions (including seven articles that have been cited in U.S. Supreme Court opinions). His scholarship also has been cited by more than 3,000 academic articles. In addition to writing law review articles, Kerr has authored popular casebooks, co-authored the leading criminal procedure treatise, and published countless blog posts at popular blogs such as the Volokh Conspiracy and Lawfare.

Kerr has briefed and argued cases in the United States Supreme Court and three federal circuits. He has testified six times before Congressional committees. In 2013, Chief Justice Roberts appointed Kerr to serve on the Advisory Committee for the Federal Rules of Criminal Procedure. In 2015, the Chief Justice again appointed him to serve on the Judicial Conference’s committee to review the Criminal Justice Act.

Kerr graduated from Princeton University and received a master’s degree in mechanical engineering from Stanford University. He earned his law degree from Harvard University, where he was executive editor of the Harvard Journal of Law and Public Policy. After law school, he clerked 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 then served as a Special Assistant U.S. Attorney in the Eastern District of Virginia and as a trial attorney in the Computer Crime and Intellectual Property Section at the U.S. Department of Justice.

Re: Niels W. Frenzen

Niels W. Frenzen was quoted about the case of Scott Warren, an activist who was arrested and charged with harboring and conspiring to transport undocumented immigrants. In 2017, a directive from then-Attorney General Jeff Sessions to prioritize cases involving the transportation of undocumented immigrants,"brought to a head the conflict between immigration enforcement and a sanctuary movement that reaches back to the 1980s," explained Frenzen. "While maintaining a spiritual element, the movement has become more political and less religious...especially as the Trump administration draws stark battle lines on immigration," he said. Frenzen's quote was also mentioned in the National Post, Daily Herald, Calgary Herald, Montreal Gazette, Leader Post, Ottawa Citizen, The London Free Press, The Star Phoenix,, The Salt Lake Tribune, and The Province.
