Alex Geisinger concentrates on the role of legal theory -- including law and economics, behavioralism and expressivism -- in the development of international law, environmental law and criminal law. 

Before coming to the law school, he served as associate dean and professor of law at Valparaiso University School of Law. He was a visiting professor at William and Mary Law School and Northwestern University School of Law. Prior to teaching, he practiced with Day, Berry & Howard in Hartford, Conn.

Professor Geisinger was elected to the American Law Institute in 2010 and currently works with the Public Interest Law Center of Philadelphia on issues of environmental justice. Before receiving his LLM from Harvard Law School, he earned his JD with high honors from the University of Connecticut School of Law. There, Professor Geisinger earned numerous honors, including the Connecticut Bar Association Award for Scholarship in Real Property and Environmental Law and the Milton Hurwitz Award and American Jurisprudence Awards for achievement in property and in torts.

Professor Geisinger’s scholarship covers theories of social norms and the law and topics in environmental law and regulation. Representative articles include "Rational Choice, Reputation and Human Rights Treaties," (with M. Stein) in the Michigan Law Review, "A Belief Change Theory of Expressive Law," in the Iowa Law Review, and "Rethinking Risk-Based Environmental Cleanup," in the Indiana Law Journal.

A co-founder and former chair of the New Law Professors Section of the Association of American Law Schools, he has also served as an advisor to the Uniform Environmental Covenant Drafting Committee of the National Conference of Commissioners on Uniform State Laws.

He served on the board of the Indiana Bar Foundation and also on the Curriculum Committee of the American Bar Association Section on Legal Education.

He received the Dean Jennifer L. Rosato Excellence in the Classroom Award in 2014 and in 2018.
