Professor Sean Sullivan joined the faculty in 2017. He teaches and writes about antitrust law, evidence law, and law and economics. Across these topics, Professor Sullivan seeks to clarify law by identifying and building upon the ways in which law depends on economics and statistics.

Before joining the Iowa Law faculty, Professor Sullivan served as an antitrust attorney at the Federal Trade Commission in Washington, DC. His practice focused primarily on the review and litigation of mergers in technology and commodity-chemical industries.

Professor Sullivan holds advanced degrees in economics and statistics. He is an associate editor of the (peer reviewed) Antitrust Law Journal and maintains an active role in the VeconLab Experimental Economics Laboratory at the University of Virginia.
