Dr. Philip A. Wallach

Philip Wallach is a senior fellow at the American Enterprise Institute (AEI), where he studies America’s separation of powers, with a focus on regulatory policy issues and the relationship between Congress and the administrative state.

Dr. Wallach’s scholarly and popular work has been published widely, including in the publications of the Brookings Center on Regulation and Markets, Studies in American Political Development, Fortune, National Affairs, National Review, Law & Liberty, Los Angeles Times, RealClearPolicy, the Bulwark, the Hill, the Wall Street Journal, and the Washington Post. A frequent conference participant, he has lectured at William & Mary, the University of Oregon, Northwestern University’s Medill School of Journalism, and the University of Michigan, among others.
