Sean Sullivan
Overview
Sean Sullivan holds the Jon and Sarah Fister Chair in Law & Economics at the University of Iowa College of Law. His research involves core questions in antitrust law and evidence—questions like why market shares tell us anything about market power and what it means for a jury to find the truth of a disputed fact. He also studies markets, negotiation, and small-sample statistical methods as an experimental economist.
Before joining the faculty at Iowa, Professor Sullivan served as an antitrust attorney at the Federal Trade Commission. His legal practice focused primarily on the review and litigation of mergers in technology and commodity-chemical spaces. Beyond law, Sullivan studies and holds advanced degrees in economics and statistics.
At Iowa, Professor Sullivan regularly teaches Contracts, Evidence, Antitrust Law, and Law and Economics. He serves as faculty advisor for the Journal of Corporation Law and the Parents and Law Students (PALS) student organization. Outside of the law school, Sullivan holds a leadership role in the Antitrust Section of the American Bar Association and chairs the editorial board of the peer-reviewed Antitrust Law Journal.
