Alexandra (Xander) Meise is a Senior Fellow at the Center for Ethics and the Rule of Law at University of Pennsylvania Law School. Before joining Penn, she was a partner in the International Disputes Practice of Mitchell Silberberg & Knupp LLP (“MSK”), where she worked to prevent, litigate, and resolve a panoply of international disputes, particularly those related to implementation of international treaties. Ms. Meise has represented and advised foreign governments, victims of human rights abuses, international corporate clients, and sovereign officials in U.S. federal court matters, international commercial arbitrations, and investment treaty arbitrations. She has also worked for international criminal tribunals, an international political development NGO, and the U.S. Department of State.

Ms. Meise’s advocacy practice focused on international arbitration (including investor-State dispute resolution and prevention), maritime boundary disputes, sovereign representation, FSIA, and enforcement litigation, and international commercial arbitration. She has also advised and trained government officials reforming their international investment laws and policies. Her human rights advising practice focused on advising governments, non-governmental organizations, and multinational corporations on human rights compliance and conflict prevention.

She lectures frequently in academic and international fora on national security, arbitration, and other issues related to international disputes, including at meetings of the Arbitration in Africa Conference Initiative, the American Society of International Law, and the ABA’s International Section. She focuses her research primarily on issues of sovereign power and immunity under international law. Professor Meise’s pro bono activities have included training new law clerks for the Supreme Court of the Republic of Zambia, representing asylum seekers before US immigration authorities, and advising No Exceptions, a non-partisan coalition of post-9/11 generation leaders supporting a full gender inclusion policy for combat roles in the U.S. military.

Ms. Meise is also a non-resident Fellow of the Columbia 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 regular contributor to The Secure Line podcast (
