About
Hayley Stillwell joined the OU Law faculty in 2024. She teaches Evidence, Evidence Lab, Remedies, and Criminal Law. Her research focuses on evidence, juries, and criminal adjudication, including empirical mock-jury studies examining how jurors evaluate evidence and reach decisions. Her recent scholarship also explores the capabilities and limitations of artificial intelligence in replicating human judgment and predicting judicial decisions.
Professor Stillwell’s scholarship has been published in the Arizona State Law Journal, the Georgetown Journal of Law and Public Policy, and the George Mason Law Review, among others, and has been cited in amicus briefs filed in the U.S. Supreme Court.
Sooner born and sooner bred, Professor Stillwell earned a B.A. summa cum laude and a J.D. with highest honors from the University of Oklahoma. In law school, she finished first in her class and earned membership in the Orders of the Coif, Barristers, and Scribes. After earning her J.D., Professor Stillwell served as a law clerk to federal and state judges at all levels of the court system, including the U.S. Courts of Appeals for the Second and Tenth Circuits, and gained valuable practice experience as a litigation associate at leading Oklahoma City and Houston law firms.
