Dominic Brennan is a postdoctoral fellow in technology and international security with the UC Institute on Global Conflict and Cooperation (IGCC) based in Washington, D.C. His research investigates the role of nuclear energy in U.S. strategic security, and emerging technologies’ impact on the global nonproliferation regime. He earned his Ph.D. in nuclear engineering from Cambridge University before a two-year stint in the UK Civil Service. His Ph.D. thesis developed bias-correcting optimization algorithms for nuclear power design and economics.

Dom’s research has been published in Lawfare, the journal of Nuclear Science and Engineering, and in the journal proceedings of the International Conference of Reactors and the International Conference on Mathematics and Computational Methods Applied to Nuclear Science and Engineering. He has presented his research at the Project on Nuclear Issues Annual Conference in the UK and the US, and NATO’s Early Career Nuclear Strategists’ Workshop. Dom has advised as a Nuclear Specialist in several CBRN Red Teams for large language model development, and to provide deep tech horizon scanning in the nuclear sector. In 2022 Dom was a delegate for the American Nuclear Society at the 27th Conference of the Parties to the United Nations Framework Convention on Climate Change. From 2023-2025, Dom worked as a senior technical adviser within the UK Government’s Department of Energy Security and Net Zero.
