The Science and Security Board (SASB) is comprised of a select group of globally recognized leaders with a specific focus on nuclear risk, climate change and emerging technologies. The SASB provides the Bulletin with objective external perspective on trends and issues in these related fields, and connects the organization to outside experts. The SASB’s responsibilities include: (1) serving as the Editorial Board of the Bulletin; (2) setting the hands of the Doomsday Clock, and authoring a supporting statement; (3) providing editorial and program advice to Bulletin staff; (4) helping track trends in global security, nuclear issues, climate change and emerging technologies; (5) identifying new experts as contributors to the Bulletin and for membership on the SASB; and (6) representing the organization at public events, including to broadcast, print and other media outlets. The SASB meets in person biannually, and its subcommittees meet more regularly.

Bronson is the President and CEO of the Bulletin of the Atomic Scientists, where she oversees the publishing programs, the management of the Doomsday Clock, and a growing set of activities around nuclear risk, climate change, and disruptive technologies. Before joining the Bulletin, she served as vice president for studies at the Chicago Council on Global Affairs, adjunct professor of global energy at the Kellogg School of Management, and senior fellow and director of Middle East studies at the Council on Foreign Relations, among other positions. Her book, Thicker than Oil: America’s Uneasy Partnership with Saudi Arabia (Oxford University Press, 2006), has been translated into Japanese and published in paperback. Her writings and commentary have appeared in outlets including Foreign Affairs, The New York Times, The Washington Post, “PBS NewsHour,” “Charlie Rose,” and “The Daily Show.” Bronson has served as a consultant to NBC News and testified before the congressional Task Force on Anti-Terrorism and Proliferation Financing, Congress’s Joint Economic Committee, and the 9/11 Commission.
Eden is Senior Research Scholar (Emeritus) at Stanford University’s Center for International Security and Cooperation. Eden is also co-chair of US Pugwash and a member of the International Pugwash Council. Her scholarly work focuses on the military and society; science, technology, and organizations; and US nuclear weapons history and policy. Eden’s Whole World on Fire: Organizations, Knowledge, and Nuclear Weapons Devastation won the American Sociological Association’s 2004 Robert K. Merton award for best book in science and technology studies. Her current research and writing (mostly historical) asks how a specific US military planning organization has enabled very good people to plan what, if put into action, could or would result in the deaths of tens or hundreds of millions of people. In other words, how do US military officers make plans to fight and prevail in nuclear war?
