Walker’s publications have appeared in the California Law Review, Duke Law Journal, Georgetown Law Journal, Michigan Law Review, Stanford Law Review, and University of Pennsylvania Law Review, among others. His article “Legislating in the Shadows” was selected as the recipient of the 2016 American Association of Law Schools Scholarly Papers Competition Award. His book Constraining Bureaucracy Beyond Judicial Review is forthcoming from the Cambridge University Press.
Walker brings to his scholarship and to the classroom the extensive practical experience of having worked in all three branches of the federal government, as well as in private practice. Before joining the Michigan Law faculty, he taught for a decade at the Ohio State University Moritz College of Law.
He clerked for Justice Anthony Kennedy on the US Supreme Court and worked for several years at a litigation boutique in Washington, DC, and on the Civil Appellate staff at the US Department of Justice, where he represented federal agencies in a variety of regulatory contexts. In 2017, he served as an academic fellow on the Senate Judiciary Committee, working on the Gorsuch Supreme Court confirmation as well as on regulatory reform legislation for Utah Sen. Orrin Hatch. From 2017 to 2021, Walker served on the bipartisan judicial advisory commission of Sen. Sherrod Brown and Sen. Rob Portman to help fill 10 federal district court vacancies in Ohio; he served as chair in 2018 and 2019.
Outside Michigan Law, Walker is a senior fellow at the Administrative Conference of the United States and past chair of the American Bar Association’s Section of Administrative Law and Regulatory Practice. He also is a regular blogger at the Yale Journal on Regulation and the section editor for Jotwell’s Administrative Law Section. In 2022, he received the Federalist Society’s Joseph Story Award.
