Sara Al-Sayed is a Postdoctoral Research Associate in the Program on Science and Global Security (SGS) at Princeton University. She received her B.Sc. degree from the German University in Cairo, Egypt, M.Sc. degree from Universität Ulm, Germany, and Ph.D. degree from Technische Universität Darmstadt, Germany – all in communications engineering, with the focus of her Ph.D. dissertation being on statistical data processing. After an appointment as a postdoctoral research and teaching associate at Technische Universität Darmstadt, she picked up an M.A. program in philosophy of technology at the same university.

Research Interests

The verification of states’ compliance with nuclear arms control, nonproliferation, and disarmament treaty obligations has always posed technical and political challenges. A largely neglected avenue to address some of these challenges is societal verification, in which civil society organizations and individuals play a direct role in verifying treaty compliance by their own state. My research centers on how new and emerging information technologies and procedures can support data collection, analysis, and secure reporting to empower civil society and whistle-blowers with regard to nuclear arms control, non-proliferation, and disarmament verification, including through the new Treaty on the Prohibition of Nuclear Weapons. Concurrently, I am writing my master’s thesis on the relationship between societal verification and the entrenchment of the nuclear order, using approaches from philosophy of technology.


I am also managing SGS’s Curriculum Resources Project, which aims to contribute to efforts countering racism and other structures of exclusion and domination in teaching and research on nuclear issues.
