On 1 July 2025, Mr Steen Søndergaard assumes his term as NATO Chief Scientist. He was appointed to the position by the North Atlantic Council earlier this year, upon recommendation by the NATO Science & Technology Board (STB), for a three-year term.
With more than 30 years of experience, Mr Søndergaard brings extensive expertise to this strategic role. He will continue the legacy of delivering timely evidence-based advice to NATO senior leadership in order to inform the Alliance's defence planning, policy- and decision-making. As the Chair of the STB, he will maintain governance focus on two main objectives: strengthening the impact of S&T results across all Instruments of Power, and ensuring that the STO-internal adaptation process delivers the expected results.
