Mariano-Florentino Cuéllar

Mariano-Florentino (Tino) Cuéllar is the tenth president of the Carnegie Endowment for International Peace. A former justice of the Supreme Court of California, he served two U.S. presidents at the White House and in federal agencies, and was a faculty member at Stanford University for two decades with appointments in law, political science, and international affairs. He chairs the board of the William & Flora Hewlett Foundation and is a member of the Harvard Corporation and the U.S. Department of State’s Foreign Affairs Policy Board.  

Cuéllar’s body of scholarship focuses on how institutions and complex organizations mediate the relationship between law, political economy, and social change in a world of shifting coalitions, geopolitical pressures, and new technologies. Areas of special focus include the development of American institutions since the late 19th century; problems of implementation and democratic legitimacy in American administrative law as the country became a geopolitical power; artificial intelligence and its relationship to law and organizations; legal doctrines and institutions affecting international security; transnational regulatory and criminal enforcement; implementation of migration and citizenship, public health, and environmental policy; and the political economy of organizations and development.

His interdisciplinary research explores how people and organizations endeavor and often struggle to reconcile aspirations for democratic responsiveness, technical expertise, and procedural fairness in an interdependent world. His scholarship broadens our understanding of what government agencies do and why they do it, and how societies and institutions seek (and often fail) to reconcile their ideals and their practices.
