Professor McGreal's SSRN Author Page

Professor McGreal was appointed the James L. Koley ’54 Professor of Constitutional Law in July 2025, and has been a Professor of Law since 2015. His teaching, research, and speaking span two fields: constitutional law—particularly religious liberty and the economic analysis of law and religion—and the design and effectiveness of corporate compliance and ethics programs.

In constitutional law, Professor McGreal has published widely on First Amendment doctrine and theory, with recent articles including Reforming the Ministerial Exception in the Villanova Law Review (2024), True Threats and the Neuroscience of Fear in Case Western Reserve Law Review (forthcoming 2025) and Resolving the Ministerial Exception's Economic Paradox in the Florida State University Law Review (forthcoming 2026). One of his current research projects applies economic analysis to claims of clergy malpractice, and another examines the relevance of historical analogies from religious persecution in Reformation Era Europe to current litigation over Ten Commandments displays in public schools.

He is co-author of the leading constitutional law student guide Questions & Answers: Constitutional Law (4th ed., Carolina Academic Press 2023), and the coursebook Skills & Values: The First Amendment (3rd ed., LexisNexis 2021).

On the compliance side, Professor McGreal has written, taught, and spoken on the subject since 1997. During that time, he was a frequent speaker at the Practising Law Institute’s annual Compliance and Ethics Workshop. For over fiften years, he wrote the annual Corporate Compliance Survey for the ABA publication The Business Lawyer, and he published the article Caremark in the Arc of Compliance History in the Temple Law Review. He founded and served as Director of the Corporate Compliance Center at South Texas College of Law (2003–06), where he taught the first course on corporate compliance and ethics programs at a US law school. He is also a founding faculty member of the Texas A&M Mays Executive MBA Program, where he has taught modules on corporate compliance and ethics since 1999.

Professor McGreal’s administrative leadership includes terms as Dean of Creighton University School of Law (2015–17) and Dean of the University of Dayton School of Law (2011–15). He was previously Director of Faculty Development and Interim Associate Dean for Academic Affairs at Southern Illinois University School of Law.

Professor McGreal was a full-time faculty member at South Texas College of Law Houston from 1996 to 2006, and at SIU School of Law from 2006 to 2011. He has also been a visiting professor at George Mason University (spring 2022) and SMU (spring 1996).

Professor McGreal received his LL.M. from Yale Law School (1994) after clerking for the Hon. Warren W. Matthews of the Alaska Supreme Court, and graduated magna cum laude from SMU Dedman School of Law (J.D. 1992), where he served as Editor-in-Chief of the SMU Law Review/Southwestern Law Journal. He holds a B.A. in Economics, cum laude, from Williams College (1989).
