Named by Benchmark Litigation as "International Arbitration Litigator of the Year" in 2023, Greg heads Wiley’s Global Disputes Practice. His practice focuses on complex commercial litigation and arbitration and the Foreign Corrupt Practices Act (FCPA). His diverse experience includes serving as lead counsel in high-stakes litigation and arbitration matters involving a wide-range of claims cutting across several industries.

Greg’s matters are frequently multifaceted, with parallel or related proceedings in multiple fora. For example, Greg represents global defense contractor, BAE Systems, in a dispute with the South Korean Government relating to a $2.5 billion program to upgrade Korea’s fleet of F16 fighter jets. Greg obtained summary judgment in a U.S. suit declaring that Korea’s claims impermissibly undermined U.S. national security interests. In so doing, he obtained the first-ever foreign anti-suit injunction against a foreign sovereign in the history of U.S. jurisprudence. Further, he convinced the Fourth Circuit to affirm the District Court’s decision, despite an amicus brief by the Executive Branch challenging BAE’s national security arguments. Greg advised BAE with respect to the parallel Korean suit. The Korean Supreme Court recently affirmed BAE's victory in that action as well.

Greg successfully represented FuelCell Energy, a publicly-traded, clean energy company, in a wide ranging dispute with an international energy company concerning exclusive rights to FuelCell’s technology in Asia and over $1 billion in claims and counterclaims. The dispute featured parallel arbitrations seated in London and Singapore, three arbitrations seated in Korea, a books-and-records demand in Delaware Chancery Court, and a securities claim in the U.S. District Court for the Southern District of New York. After a bench trial, Greg obtained a landmark decision for FuelCell in the Delaware action. Since then, the parties entered into a settlement agreement confirming FuelCell’s exclusive rights to market its technology in Asia and includes a multi-million dollar order for FuelCell’s modules. All claims against FuelCell were dismissed with prejudice and without compensation.

Greg's FCPA experience runs the gamut, including managing world-wide internal investigations; conducting due diligence on international agents, joint venture partners, and other third parties; and designing corporate anti-corruption compliance and training programs.

Greg also serves as a member of the Wiley Management Committee.
