Warren Grimes honed his expertise in antitrust and other public policy issues during his 16 years in government service. Following a year as a litigator with the firm of O'Melveny & Myers and three years as a fellow at the Max Planck Institute in Germany, he began his government career as an attorney advisor to the U.S. Department of Justice, Office of Legal Counsel. There he drafted legal opinions for the President and other executive branch officials. He was then recruited by the Federal Trade Commission (FTC) and represented the agency in many federal court antitrust proceedings and at antitrust meetings of the Organization for Economic Cooperation and Development headquartered in Paris, France. Professor Grimes then moved to the U.S. House of Representatives where he served for 8 years as chief counsel of the Judiciary Committee's Subcommittee on Monopolies and Commercial Law.
"On occasion, a scholarly paper can impact policy, which is extremely satisfying. But writing also allows me to refine my thinking and improve my ability to teach my subject."
After several years as an adjunct professor at Georgetown University Law Center and Columbus School of Law of Catholic University, Professor Grimes accepted an appointment to Southwestern's full-time faculty in 1988. He was recognized for his teaching excellence and scholarship with the Irwin R. Buchalter Professorship in 2000 and the Irving D. and Florence Rosenberg Professorship in 2006. Professor Grimes served as Associate Dean for Research from 2016 to 2019. With his international reputation continuing to expand, he has served as a visiting professor at Nihon University in Tokyo, Japan, and as a lecturer on international antitrust enforcement at the Comparative Competition Law Conference at the College of Europe in Brussels, among other forums around the world.
Professor Grimes is co-author of the definitive antitrust law text for lawyers and law students, The Law of Antitrust: An Integrated Handbook with the late Professor Lawrence Sullivan and has written numerous scholarly articles on related topics.
Professor Grimes chaired the Los Angeles County Bar Association Antitrust and Trade Regulation Section and is a member of the Executive Committee, and serves on the Advisory Board of the American Antitrust Institute. In 2009, he was one of two American professors appointed to the Scientific Advisory Board of the Max Planck Institute for Intellectual Property, Competition, and Tax Law in Munich Germany, which is made up of experts from Europe and North America.
