About

Nicolas Flagey is a distinguished observational astronomer and systems engineer whose work bridges the design of next-generation astronomical facilities with the study of the interstellar medium. His primary research areas include the physics of the interstellar medium, infrared astronomy, and the development of large-scale spectroscopic survey telescopes. Flagey has made major contributions to the Maunakea Spectroscopic Explorer (MSE), a transformative 10-meter class facility that will replace the Canada-France-Hawaii Telescope. He has led the implementation of rigorous systems engineering methodologies for MSE, ensuring that its highly multiplexed design—featuring a segmented primary mirror and robotic fiber positioners—meets ambitious scientific goals. His work on the characterization of polycyclic aromatic hydrocarbons and interstellar dust has also advanced our understanding of star formation and galaxy evolution. With over 4,000 citations across his career, Flagey’s impact is evident in both the technical foundations of future observatories and the fundamental astrophysics they will explore. His notable achievements include leadership roles in major instrumentation projects and contributions to the Spitzer and Herschel space telescopes, making him a key figure in shaping the future of ground-based spectroscopy.
