Matt is a seasoned litigator fortunate to do work he loves, for clients with inspiring missions, alongside phenomenal colleagues.

While at the firm, Matt has led a broad coalition of public health and environmental groups, working with several States, localities, and companies on multiple challenges to the Trump Administration's decisions weakening federal clean-car standards and rescinding state authority to set emission standards for those vehicles. Additionally, Matt has litigated successfully to rescind a federal nonenforcement policy for super-polluting trucks; to vacate a midnight rule that prejudiced an agency against using the best available science on health effects of pollution; and to defend Michigan's pathbreaking lead-and-copper regulations passed in the wake of the Flint water crisis.

Matt also maintains an active appellate practice supporting state and local governments in eminent domain and inverse condemnation ("takings") cases. He has authored certiorari and merits stage briefs for municipalities in the Supreme Court, as well as for amici curiae representing governmental interests.

A 2010 graduate of Harvard Law School and the Kennedy School of Government, Matt served as a law clerk to Judge William C. Bryson of the U.S. Court of Appeals for the Federal Circuit. Before joining the firm, Matt spent six years as an appellate attorney in the Environment and Natural Resources Division of the U.S. Department of Justice, where he briefed and argued dozens of federal and state appeals on topics including pollution control, natural resources, Indian law, and Fifth Amendment takings. Matt also worked closely with the Office of the Solicitor General to draft jurisdictional and merits briefs in the Supreme Court on those topics and a range of other issues. He twice received the Assistant Attorney General's Award for Excellence and received a Bronze Medal from the U.S. Environmental Protection Agency for his advocacy. Matt earlier served as a Law and Policy Associate in the White House Office of Energy and Climate Change at the outset of the Obama Administration.

Matt is a member of the bars of New York and the District of Columbia.
