Slayton’s research and teaching examine the relationships between and among risk, governance, and expertise, with a focus on international security and cooperation since World War II. Slayton’s current book project, Shadowing Cybersecurity, examines the historical emergence of cybersecurity expertise. Shadowing Cybersecurity shows how efforts to establish credible expertise in corporate, governmental, and non-governmental contexts have produced varying and sometimes conflicting expert practices. Nonetheless, all cybersecurity experts wrestle with the irreducible uncertainties that characterize intelligent adversaries, and the fundamental inability to prove that systems are secure. The book shows how cybersecurity experts have paradoxically gained credibility by making threats and vulnerabilities visible, while acknowledging that more always remain in the shadows.

Slayton’s first book, Arguments that Count: Physics, Computing, and Missile Defense, 1949-2012 (MIT Press, 2013), shows how the rise of a new field of expertise in computing reshaped public policies and perceptions about the risks of missile defense in the United States. In 2015, Arguments that Count won the Computer History Museum Prize. In 2016, Slayton was awarded a National Science Foundation CAREER grant for her project “Enacting Cybersecurity Expertise.” In 2019, Slayton was also a recipient of the United States Presidential Early Career Award for Scientists and Engineers, for her NSF CAREER project.

He is the former co-director of Stanford University's Center for International Security and Cooperation, having served seven years in that capacity through January 2000.

May is a director emeritus of the Lawrence Livermore National Laboratory, where he worked from 1952 to 1988, with some brief periods away from the Laboratory. While there, he held a variety of research and development positions, serving as director of the Laboratory from 1965 to 1971.

May was a technical adviser to the Threshold Test Ban Treaty negotiating team; a member of the U.S. delegation to the Strategic Arms Limitation Talks; and at various times has been a member of the Defense Science Board, the General Advisory Committee to the AEC, the Secretary of Energy Advisory Board, the RAND Corporation Board of Trustees, and the Committee on International Security and Arms Control of the National Academy of Sciences. He is a member of the International Institute on Strategic Studies, and a Fellow of the American Physical Society and the American Association for the Advancement of Science.

May received the Distinguished Public Service and Distinguished Civilian Service Medals from the Department of Defense, and the Ernest Orlando Lawrence Award from the Atomic Energy Commission, as well as other awards.

His current research interests are nuclear weapons policy in the US and in other countries; nuclear terrorism; nuclear and other forms of energy and their impact on the environment, health and safety and security; the use of statistics and mathematical models in the public sphere.

May is continuing work on creating a secure future for civilian nuclear applications. In October 2007, May hosted an international workshop on how the nuclear weapon states can help rebuild the consensus underlying the Nuclear Non-Proliferation Treaty (NPT). Proceedings and a summary report are available online or by email request. May also chaired a technical working group on nuclear forensics. The final report is available online.

In April 2007, May in cooperation with former Secretary of Defense William J. Perry and Professor Ashton Carter of Harvard hosted a workshop on what would have to be done to be ready for a terrorist nuclear detonation. The report is available online at the Preventive Defense Project. A summary, titled, "The Day After: Action Following a Nuclear Blast in a U.S. City," was published fall 2007 in Washington Quarterly and is available online.

Recent work also includes a study of nuclear postures in several countries (2007 - 2009); an article on nuclear disarmament and one on tactical nuclear weapons; and a report with Kate Marvel for the American Academy of Arts and Sciences on possible game changers in the nuclear energy industry.

Allen S. Weiner is senior lecturer in law and director of the Stanford Program in International Law at Stanford Law School. He is also the co-director of the Stanford Center on International Conflict and Negotiation. He is an international legal scholar with expertise in such wide-ranging fields as international and national security law, the law of war, international conflict resolution, and international criminal law (including transitional justice). His scholarship focuses on international law and the response to the contemporary security threats of international terrorism, the proliferation of weapons of mass destruction, and situations of widespread humanitarian atrocities. He also explores the relationship between international and domestic law in the context of asymmetric armed conflicts between the United States and nonstate groups and the response to terrorism. In the realm of international conflict resolution, his highly multidisciplinary work analyzes the barriers to resolving violent political conflicts, with a particular focus on the Israeli-Palestinian conflict. Weiner’s scholarship is deeply informed by experience; for more than a decade he practiced international law in the U.S. Department of State, serving as an attorney-adviser in the Office of the Legal Adviser and as legal counselor at the U.S. Embassy in The Hague. In those capacities, he advised government policy-makers, negotiated international agreements, and represented the United States in litigation before the Iran-United States Claims Tribunal, the International Criminal Tribunal for the Former Yugoslavia, and the International Court of Justice. He teaches courses in public international law, international conflict resolution, and international security matters at Stanford Law School.

Weiner is the author of "Constitutions as Peace Treaties: A Cautionary Tale for the Arab Spring” in the Stanford Law Review Online (2011) and co-author (with Barry E. Carter) of International Law (6th ed. 2011). Other publications include “The Torture Memos and Accountability" in the American Society of International Law Insight (2009), "Law, Just War, and the International Fight Against Terrorism: Is It War?", in Intervention, Terrorism, and Torture: Contemporary Challenges to Just War Theory (Steven P. Lee, ed.) (2007), ”Enhancing Implementation of U.N. Security Council Resolution 1540: Report of the Center on International Security and Cooperation” (with Chaim Braun, Michael May & Roger Speed) (September 2007), and "The Use of Force and Contemporary Security Threats: Old Medicine for New Ills?", Stanford Law Review (2006).

Weiner has worked on several Supreme Court amicus briefs concerning national security and international law issues, including cases brought involving "war on terror" detainees.  He has also submitted petitions before the United Nations Working Group on Arbitrary Detention on behalf of Vietnamese social and political activists detained by their governing for the exercise of free speech rights.

Weiner earned a BA from Harvard College and a JD from Stanford Law School.
