Alexandra (Xander) Meise’s research, which draws upon her public and private service spanning five continents, probes the intersection of public and private international law, with a focus on the limits of sovereign power under international law in conflict and public emergency contexts. Her current work is centered on the national security implications of the exercise of sovereign power over strategic resources. Before coming to Penn, Meise spent over a decade in practice preventing and resolving international disputes. This work included representing and advising sovereign governments and other clients in U.S. courts, in treaty-based international arbitrations and public international law disputes, and in designing and implementing rule of law-based legal reforms and human-rights best practices. She teaches International Human Rights Law at Georgetown University Law Center, is a non-resident Fellow at the Center on Sustainable Investment (a Joint Center of Columbia Law School and The Earth Institute at Columbia University), a Political Partner of the Truman National Security Project, and a two-time NGO Legal Observer to the Military Commissions at Guantanamo Bay.
