Ryan is the co-chair of Shook’s Antitrust practice. He focuses on litigation, transactions, investigations, and counseling with a competition or consumer-protection nexus.

Ryan previously served at the Antitrust Division of the Department of Justice, working as a Digital Markets Trial Attorney. Ryan’s DOJ work included the landmark United States v. Google case, merger litigation, tech investigations, price-fixing investigations, and coordination with state and international enforcers. 

Before joining the DOJ, Ryan was an antitrust partner in Sidley Austin’s San Francisco office. He helped clients win antitrust cases in the Northern District of California and around the country. He also litigated FTC consumer protection matters as well as antitrust and non-antitrust consumer class actions. 

Ryan is an adjunct professor at UC College of the Law, San Francisco, where he co-teaches Antitrust and Intellectual Property. He also has written for a wide range of publications on antitrust-related topics, including pieces on the direct purchaser rule, refusal to deal standards, and predatory pricing claims. 

Before going to law school, Ryan taught American history and coached cross-country and track in Louisiana. He is a fan of Ohio sports teams and an avid, but slowing, runner.
