Geoffrey Chapman is a Research Associate at King’s College London's Centre for Science and Security Studies (CSSS). His research focuses on British nuclear security in the aftermath of Brexit and the Coronavirus pandemic. His doctoral thesis examined the role of tacit knowledge in shaping outcomes within Britain’s nuclear weapons programme.

Geoffrey is a part time lecturer on the Department of War Studies Hacking Defence Problems course. He is also a contributing lecturer on issues such as the intangible barriers to proliferation, non-state actor uses of chemical weapons and OSINT education.

Dr Chapman contributes to the CSSS' work on international nuclear security education and security culture assessment, with a particular focus on insider threats.

He has also been involved in OSINT projects, including work for IHS Markit Jane’s and has delivered papers and presentations for them on CBRN issues within the context of the Syrian Civil War.

Previously published papers include comparing Islamic State and Jabhat al-Nusra chemical weapons usage and a co-authored paper on the lessons that future actors may learn from the use of chemical weapons within Syria. His research continues to monitor the international prohibition on chemical weapons and its impact on the future of arms control.
