At Crowell & Moring, he practices in the International Trade practice group where his practice covers compliance with U.S. economic sanctions, export controls and antiboycott regimes, and anti-money laundering (AML) laws and regulations, including by providing day-to-day compliance guidance, developing compliance programs including through on-site compliance trainings, responding to government inquiries, conducting internal investigations, representing them during civil and criminal enforcement proceedings, and, in collaboration with colleagues, managing the potential conflict of laws which can arise from the interaction between extraterritorial impacts of U.S. regulations and third country "blocking" laws or data privacy regulations. Dj splits his time between Washington and London, working regularly with European clients and colleagues to provide coordinated guidance on U.S., U.K., and EU sanctions compliance and enforcement. Dj also has extensive experience in international mergers and acquisitions, advising both buyers and sellers regarding the international trade implications of a potential deal.
