Sara Al-Sayed is a Postdoctoral Research Associate in the Program on Science and Global Security (SGS) at Princeton University. She received her BSc degree from the German University in Cairo, Egypt, an MSc degree from Universität Ulm, Germany, and the PhD degree from Technische Universität Darmstadt, Germany – all in communications engineering, with the focus of her PhD dissertation being on statistical data processing. After an appointment as a postdoctoral research and teaching associate at Technische Universität Germany, she picked up an MA 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 the new Treaty on the Prohibition of Nuclear Weapons.
