As the firm's Cross-Border Litigation and Arbitration Chair and member of the International Arbitration & Trade and White-Collar Defense Practice Groups, Mehmet represents entities, individuals, and sovereigns in cross border disputes and arbitrations, as well as in government investigations, internal investigations involving Foreign Corrupt Practices Act and export violations, and U.S. economic sanctions violations. Likewise, Mehmet is known for assisting foreign companies across industries—construction, infrastructure, energy, and textiles, to name a few—looking to enter the U.S. market and expand their global reach.

Having been named a 2021 Northeast Trailblazer by the American Lawyer and selected as a “Rising Star” by SuperLawyers multiple times, Mehmet knows his way around a courtroom and has successfully acted on behalf of foreign and domestic clients in state, federal, and appellate court proceedings nationwide in disputes involving contracts, enforcement of arbitration awards, international law and sovereign immunity, and trade secret violations. On the global stage, Mehmet has represented clients before major international arbitral organizations, including the International Centre for Settlement of Investment Disputes (ICSID) and the International Court of Arbitration (ICC).

Prior to joining M&R, Mehmet was a partner at Breeding Henry Baysan, a boutique law firm with an overseas presence, and before that he worked for an AmLaw100. He is a frequent presenter at seminars on U.S. and international law; a member of the Turkish Industry and Business Association (TUSIAD); and serves as co-chair of the U.S. Chamber of Commerce’s U.S.-Turkey Business Council Ad Hoc Legal Working Group.
