Gregory F. Treverton

Gregory F. Treverton
Former Chairman,
National Intelligence Council

Gregory F. Treverton served as the Chair of the U.S. National Intelligence Council (NIC) from 2014 to January 2017. The NIC is the interagency arm for current intelligence support to senior policymakers. Within the NIC, Treverton led a 150-person analytic staff, focusing on driving opportunities for more strategic analyses – those that seek to put issues in a broader context or longer time horizon – amidst the press of consuming crises ranging from Ukraine to Syria, Iraq and Afghanistan, to Africa. During his tenure at the NIC, Treverton pressed innovation in analytic methods, creating a methodology cell and incorporating both an unclassified and classified "prediction market" as kind of a "red team" check on assessments.

He served earlier in government on the staff of the first Senate Select Committee on Intelligence, on the National Security Council staff and as Vice Chair of the NIC.

For many years, he worked at the RAND Corporation, where he directed several centers, most recently the RAND Center for Global Risk and Security, which he established by recruiting Advisory Board members, developing project ideas and raising funding. Within this role, his executive projects ranged widely across security issues – from Track II diplomacy in Sudan, to assessing the financial crises after 2009, to exploring the implications on interconnected threats to the global "commons" (disease, drought and climate change), to the future of policing.

Treverton was president of the Pacific Council on International Policy, a senior fellow at the Council on Foreign Relations, and assistant director of the International Institute for Strategic Studies in London.

He has been on the faculty of Harvard’s Kennedy School of Government and Columbia’s School of International and Public Affairs. He serves as a senior fellow for the National Defence University in Stockholm, building a research and training project on homeland security intelligence and managing an annual global conference.

He has written widely on intelligence, strategy and national security. Treverton’s latest books are National Intelligence and Science: Beyond the Great Divide in Analysis and Policy (with Wilhelm Agrell), Oxford University Press, 2015; and Dividing Divided States, University of Pennsylvania Press, 2014.
