Matthew H. Adler is a partner in the Litigation Department of Pepper Hamilton LLP. Mr. Adler chairs the International and Domestic Arbitration Practice Group and is former co-chairman of the Trial and Dispute Resolution Practice Group. He is a past member of the firm’s Executive Committee.

Mr. Adler began his legal career at a large Washington, D.C., law firm, where he worked on a $1 billion lawsuit brought in the Iran-United States Claims Tribunal in The Hague, Netherlands, by a consortium of U.S. oil companies against Iran. That experience brought him to government service. In 1986, he joined the U.S. Department of State's Office of the Legal Adviser, where he litigated claims by the United States against Iran at the Claims Tribunal. In 1988, his State Department duties shifted to counsel to the Bureau of InterAmerican Affairs, where he worked on a number of Central and South American foreign policy issues. Mr. Adler joined Pepper Hamilton in 1989 and was elected a partner in 1992.

Mr. Adler has a strong interest in the continued practical development of international law as a dispute resolution mechanism, and he has published a number of articles on this topic in the United States and abroad, including in Northwestern University School of Law’s Journal of International Law and Business, The International and Comparative Law Quarterly, Georgetown Law School’s Law and Policy in International Business, the U.S.-Mexican Law Journal, and the Fordham International Law Journal. These works cover the subjects of expropriation, international terrorism, investment dispute resolution with Latin American countries, and enforcement of international judgments.

Mr. Adler lectures frequently to professional groups on these topics, most recently at the Dublin (Ireland) Bar’s Arbitration Day in November 2018. From 2005 to 2013, Mr. Adler was an adjunct professor of law at Rutgers Law School. Since 2015, he has been an adjunct professor of law at University of Virginia School of Law, where he teaches arbitration. He is the author of the law school textbook Commercial Arbitration: Cases, Problems and Practice (Carolina Academic Press 2017).

Mr. Adler serves as a member of the U.S. Department of State's Working Group on Judgments, which is negotiating a multilateral treaty on transnational enforcement of civil monetary judgments for presentation to the Senate. He is also a member of the Secretary of State’s Advisory Committee on Private International Law, and a former vice chair of the American Bar Association’s Section on International Law, Subcommittee on Private International Law.
