Ryan has particular experience with Department of Justice, Federal Trade Commission (“FTC”), Consumer Financial Protection Bureau (“CFPB”), Department of Health and Human Services (“HHS”), and State Attorney General investigations, and substantive expertise regarding federal, state, and international consumer protection, privacy and cybersecurity laws, regulations, and standards.

Ryan has served on the Board of Directors of the Faculty of Federal Advocates and the Magistrate Judge Merit Selection Panel for the District of Colorado. He graduated summa cum laude and Phi Beta Kappa from Princeton University with an A.B. from the School of Public and International Affairs. He received his J.D. from Yale Law School, where he served on the Board of the Yale Law Journal and as a civil procedure teaching assistant. After graduating from law school, Ryan clerked for the Honorable David M. Ebel on the United States Court of Appeals for the Tenth Circuit.

Before joining Gibson Dunn, Ryan served as an Assistant United States Attorney in the District of Colorado. He coordinated the District’s computer hacking prosecutions, served as its subject matter expert on electronic surveillance law, and investigated and prosecuted a wide range of crimes, including computer intrusions, denial of service attacks, theft of proprietary business information, identity theft, pharmaceutical misbranding, wire fraud, mail fraud, and murder. In addition to trying cases before nearly every judge in the District, he led dozens of criminal investigations and argued multiple appeals before the United States Court of Appeals for the Tenth Circuit. As a result of Ryan's work, the United States Attorney awarded him the District’s Distinguished Service Award and the U.S. Attorney’s Award of Excellence.
