March 3, 2020

CNS is extraordinarily pleased to announce that Dr. Ian J. Stewart has been appointed the new Executive Director of our Washington, DC, office.


Dr. Stewart joins CNS from King’s College London (KCL), where he established and led KCL’s counterproliferation and trade initiative, Project Alpha. Previously, he served as a nuclear engineer with the British Ministry of Defence, working on nuclear deterrent and nonproliferation issues.

“Ian’s leadership experience and exceptional insight into nonproliferation challenges and opportunities will be an important driver in CNS’s research focus and strategy in the years ahead,” said Dr. William C. Potter, founding director of CNS. “With his strong academic, technical, and policy background—as well as demonstrated organizing and management skills—Ian will be able to harness CNS’s existing talent and ensure our continued success in nonproliferation education and training.”

Dr. Stewart holds Masters degrees in nuclear science and technology and electrical and electronic engineering from KCL, where he also earned his PhD in 2011. At CNS, his main area of research relates to nonproliferation and illicit trade. His research focuses on implementation and enforcement of export controls as well as evasion of these measures. Secondary research interests relate to open-source intelligence and nuclear history.
