David Kenneth Smith is a Visiting Senior Research Fellow in the Department of War Studies. His work focuses on technical outreach to address the threat from nuclear and other radioactive material out of regulatory control. He regularly participates in forums and outreach sponsored by the Centre for Science & Security Studies at King's College London, the International Atomic Energy Agency, the Lawrence Livermore National Laboratory USA and AWE - Atomic Weapons Establishment UK. He is a emeritus member of the Nuclear Forensics International Technical Working Group (ITWG) where he served in executive roles for more than two decades.

From 2010 to 2020, David served as the Nuclear Security Coordinator (Forensics) [P5] in the Division of Nuclear Security at the International Atomic Energy Agency (IAEA) in Vienna, Austria. There, he led the IAEA radiological crime scene response and nuclear forensic science team. From 1987 to 2010, David held various leadership and technical staff positions in nuclear test, nuclear security and international security engagement programmes at Lawrence Livermore National Laboratory USA.

He graduated with an AB and departmental honours in geological sciences from Hamilton College in Clinton, New York USA in 1979 and a MSc in geochemistry from the University of California, Riverside, California USA in 1982. In 1986, David was elected to membership in Sigma Xi, the international scientific honour society. He is also a member of the American Geophysical Union (AGU).
