Harlan Fiske Stone Professor of Constitutional Law, Columbia Law School
A leading administrative and constitutional law scholar, Gillian Metzger ’96 writes and teaches in the areas of administrative law, constitutional law, and federal courts, with an emphasis on federalism and privatization. In 2023-2024, she served as Acting Assistant Attorney General and Deputy Assistant Attorney General in the Office of Legal Counsel in the Department of Justice.
Metzger's recent work covers topics ranging from constitutional attacks on the administrative state to appropriations, administrative law under the Roberts Court, and the role of administrative agencies in a polarized world. In 2015, Metzger won the American Bar Association Administrative Law Section Annual Scholarship Award for “The Constitutional Duty to Supervise,” which examined presidential control and oversight of the modern administrative state. She is a co-editor of Gellhorn & Byse’s Administrative Law: Cases and Comments, 13th ed. (Foundation Press, 2023), a seminal administrative law casebook.
Professor Metzger was recently elected to the American Academy of Arts & Sciences and is a Senior Fellow of the Administrative Conference of the United States.

CCG brings together a diverse group of constitutional scholars to explore policy areas such as health care, civil rights, immigration, financial regulation, and national security.
Metzger also has co-authored and filed numerous amicus briefs in major constitutional and administrative law challenges before the Supreme Court and other courts.
