I’ve taught law at the University of Virginia since 1979, focusing on issues of foreign relations, national security, international law, international business, taxation, and all things Russian. I also worked as a lawyer and adviser for the Departments of Treasury in the Clinton administration, State in the George W. Bush administration, and Defense in the Trump and Biden administrations. Before becoming a lawyer I got a graduate degree in Soviet Studies and worked briefly as an analyst doing Soviet politics at the Central Intelligence Agency. I have worked as a litigator or expert witness in many legal proceedings, U.S., foreign, and international, involving Russians and the Russian Federation.
