Paolo Di Rosa heads the firm's global International Arbitration group. His practice centers on the representation of sovereign states and private sector companies worldwide in international arbitration, litigation, and public international law matters, including in particular disputes between investors and states under investment treaties. Although his practice spans all geographic regions of the globe, he has especially extensive experience in legal matters relating to Latin America (acquired both in the private sector and the US federal government), along with a fully bilingual and bicultural background.

Mr. Di Rosa has been recognized as a leading practitioner of international arbitration in the most recent editions of publications such as Chambers USA, Chambers Global, Chambers Latin America, The Legal 500 US, The Legal 500 Latin America, Best Lawyers in America, The International Who's Who of Commercial Arbitration, Super Lawyers, and Euromoney's Guide to the World's Leading Experts, among others. He has also been recognized as a public international law specialist in the most recent editions of Chambers Global.

He has served as an arbitrator in different types of international arbitration. In 2009, the United States Government named Mr. Di Rosa as party-appointed arbitrator in the NAFTA arbitration CANACAR v. United States of America (currently suspended). In December 2015, President Barack Obama announced that he would be nominating Mr. Di Rosa as one of the four US members of the ICSID Roster of Arbitrators. See White House Press Release. The designation was formalized on February 23, 2016. Mr. Di Rosa is also a frequent speaker and panelist at international conferences.

Mr. Di Rosa provides legal services to private sector and sovereign clients on matters involving international arbitration; enforcement of arbitral awards; international litigation; transactions involving governmental entities; and public international law matters (including sovereign immunity).

Mr. Di Rosa has substantial government experience as a result of his service as a senior-level lawyer at the US Department of State during the Clinton Administration. He was a member of the Senior Executive Service of the US Government, with the rank of Assistant Legal Adviser at the State Department legal office. As head of the Office of the Legal Adviser for Western Hemisphere Affairs, he had supervisory or direct responsibility for legal matters pertaining to US relations with all countries in Latin America and the Caribbean, as well as Canada. During his tenure at the US State Department, Mr. Di Rosa was awarded a Superior Honor Award as well as a Meritorious Honor Award.
