Thokozile Kabini is a pre-doctoral fellow at Princeton University’s Program on Science and Global Security. She holds a master’s degree in Nuclear Physics from the University of Pretoria in South Africa, where she specialized in nuclear and radiation science. She holds undergraduate degrees in physical sciences and in international relations. In 2012 she joined the South African Nuclear Energy Corporation and in 2014 became a nuclear forensics analyst, with a focus on the analysis of nuclear materials using non-destructive techniques. Thokozile also worked as part of the team at the South African radionuclide laboratory (ZAL14) responsible for analyzing radionuclide samples from international monitoring stations supporting the Comprehensive Nuclear-Test-Ban Treaty Organization. She received training in nuclear forensics measurement at Los Alamos National Laboratory, and a Robin Copeland Memorial Fellowship for next-generation women from the global south interested in nonproliferation and international security.

Research Interests

Thokozile’s research interest revolves around the intersection of nuclear forensics, the Treaty on the Prohibition of Nuclear Weapons (TPNW), and issues related to disarmament and nonproliferation. Her current research explores the application of nuclear forensics approaches,  methods and tools to environmental radiological contamination assessment and remediation in the context of the TPNW. This work combines nuclear science, environmental studies, international law, national regulations on radiation safety and policy analysis to address the environmental legacies of nuclear weapons testing. She also is interested in nuclear forensics and environmental sampling as a tool for nuclear disarmament and nonproliferation verification under the TPNW and more broadly.
