Fitzpatrick joined IISS in October 2005 after a 26-year career in the US Department of State, including as Deputy Assistant Secretary for Non-Proliferation (acting) and, earlier in his career, as North Korea desk officer. His diplomatic postings also included Vienna, in charge of liaison with the International Atomic Energy Agency, as well as postings in Seoul, Tokyo and Wellington. He earned a Master’s degree in Public Policy from the Kennedy School of Government at Harvard University. A dissertation he wrote on Korean unification while attending the Japanese National Institute of Defence was published in journals in Japan and South Korea.
