Geoff was named to the French-American Foundation’s 2019 U.S. class of Young Leaders. Created in 1981, the Young Leaders program is a prestigious two-year transatlantic leadership program that brings together a group of 40 French and American rising stars under 40, from an array of sectors to forge bonds and help address global challenges.

Geoff also maintains a significant pro bono practice, a highlight of which is his representation of a class of individuals, including mentally disabled adults, residing in so-called adult homes in New York City. The class sued the state of New York, claiming that these homes violated the “integration mandate” of the Americans with Disabilities Act (ADA). After ten years of litigation, the parties reached a landmark settlement to end the state's decades-long discrimination.

Geoff is the co-author of “Ownership or Use? Civilian Property Interests in International Humanitarian Law,” which appeared in the 49th volume of Harvard International Law Journal in 2008.
