Matt Mountain is an American astronomer and science administrator known for his leadership roles in major U.S. astronomical institutions. He served as the director of the National Optical Astronomy Observatory (NOAO) from 2008 to 2016, overseeing the operation of several prominent ground‑based telescopes and the implementation of a wide range of astronomical research programs. In 2016, Mountain was appointed president of the Association of Universities for Research in Astronomy (AURA), the nonprofit organization that manages multiple national observatories and research facilities, a position he held until 2020.
In 2014, Mountain was selected as the founding director of the Large Synoptic Survey Telescope (LSST) project, which was later renamed the Vera C. Rubin Observatory. Under his direction, the project progressed through critical design, construction, and early‑science phases, aiming to conduct a ten‑year survey of the southern sky that will generate an unprecedentedly large and detailed astronomical dataset. He stepped down from the Rubin Observatory directorship in 2022, after having helped establish its scientific and technical foundations.
Mountain earned his doctorate in astronomy (or astrophysics) from the University of California, Berkeley, where his research focused on observational studies of galaxies and active galactic nuclei. Prior to his tenure at NOAO, he held research positions at several institutions, including the Jet Propulsion Laboratory and the Space Telescope Science Institute, contributing to the development of instrumentation and data analysis techniques for space‑based and ground‑based observatories.
His career has been marked by a focus on advancing observational capabilities, fostering international collaboration, and promoting data‑intensive astronomy. Mountain has been a vocal advocate for open data policies and for the integration of new technologies—such as high‑performance computing and machine learning—into astronomical research workflows.
