His work has appeared in Science, the Journal of Peace Research, the Journal of Cyber Policy, and the Bulletin of the Atomic Scientists among other outlets and has been variously supported by the Founder’s Pledge Fund, Carnegie Corporation of New York, MacArthur Foundation, and the U.S. Department of Energy’s Nuclear Science and Security Consortium.

LEAH WALKER

Leah Walker is the Lab Director for the Berkeley Risk and Security Lab. She oversees the Lab’s interdisciplinary research portfolio which includes nuclear arms control, nuclear weapons policy, defense analyses, emerging defense technologies, the governance of emerging technologies, industrial policy, and strategic competition. Leah also conducts research on the governance of military and commercial artificial intelligence, Russian and Chinese nuclear posture and modernization, nuclear and radiological security, and maritime security and strategy.

Elaine Korzak

Elaine Korzak is a research scholar at the Berkeley Risk and Security Lab focusing on
international cybersecurity governance. She is also an affiliate at the Center for International Security and Cooperation (CISAC) at Stanford University.
Her research covers international legal, policy, and governance aspects in cybersecurity, including norms and international law governing state conduct in cyberspace, cybersecurity negotiations at the United Nations, cyber policy positions and diplomatic strategies of states (in particular Russia and China), and international export controls for commercial spyware. Her work has appeared in the Oxford Handbook of Cyber Security, the Routledge Handbook of International Cybersecurity, the Georgetown Journal of International Affairs, the Bulletin of the
Atomic Scientists, and RUSI Journal. Her commentary has been published in Lawfare, Just Security, and Net Politics.  

Previously, Elaine was a cybersecurity postdoctoral fellow at the Center for International Security and Cooperation (CISAC) and a national fellow at the Hoover Institution, both at Stanford University, before leading the Cyber Initiative at the Middlebury Institute of International Studies at Monterey (MIIS). She holds a PhD in War Studies and an MA in International Peace and Security from King’s College London, as well as an LL.M. in Public International Law from the London School of Economics and Political Science (LSE).

Peter Rautenbach

Peter Rautenbach is a researcher specializing in emerging technologies, their intricate interconnections, and associated conflict risks. In Fall 2024, he will begin his PhD in Politics at the University of Leicester, where he will investigate the psychological impacts of using AI ‘advisors’ on human decision-making during nuclear crises.
Peter holds an MSc in International Relations from the London School of Economics and Political Science. He completed a fellowship with the Cambridge Existential Risks Initiative, where he examined the implications of machine learning on nuclear weapon command systems and the risk of inadvertent use. This research has been published in outlets such as the Bulletin of the Atomic Scientists and Arms Control Today.
Initially focused on nuclear weapon technology, Peter has broadened his scope to encompass a range of conflict-related issues involving AI systems, geoengineering, and small-modular nuclear reactors.

Tyrone Pater

Tyrone Pater is a Tech Diplomacy Fellow at the Berkeley Risk & Security Lab and the Senior Advisor for Innovation, Technology & Science at the Netherlands Consulate General in San Francisco. Pater is especially interested in how governments can work together across likeminded countries, private sector and academia to effectively stimulate research and innovation in key critical and emerging technology areas. His focus areas include wide-ranging technologies such as artificial intelligence and cybersecurity, having a particular interest in how developments in these areas can affect international strategic competition, research security, and economic security.

Before joining the Netherlands government, Tyrone worked in the telecommunications industry at Liberty Global. He is an alumni of both the University of Amsterdam and the Vrije Universiteit Amsterdam.
