Buell T. Jannuzi has served as the seventh Director of Steward Observatory and Head of the Department of Astronomy of The University of Arizona since 2012. Jannuzi was previously the Director of Kitt Peak National Observatory and Associate Director of the National Optical Astronomy Observatory (2005- 2010) during his 17-year tenure as a member of the scientific staff of NOAO. He earned degrees at Harvard College and the University of Arizona (Ph.D. in Astronomy). He then spent five years as a member of the Institute for Advanced Study (IAS) in Princeton, N.J., and was recognized in 1993 with the award of a NASA Hubble Fellowship.

His main scientific interests include the formation and evolution of individual, groups, and large-scale structures of galaxies, the determination of the physical processes that produce quasars and other active galactic nuclei, and the properties of massive black holes. 

Jannuzi is a member of the Board of the Event Horizon Telescope Collaboration, which was recognized with many group awards, including the 2020 Breakthrough Prize in Fundamental Physics for their work imaging and analyzing the black hole in M87. Jannuzi has been heavily involved with many large surveys of the universe, including one of the original three “Key Projects” for the Hubble Space Telescope, the Quasar Absorption Line Survey, and was co-Principal Investigator for the NOAO Deep Wide-Field Survey.  

Jannuzi has served on the Board of Directors or Science Advisory Committees of numerous major ground-based and space observatories, including the NASA Spitzer Space Telescope, NASA Fermi Space Telescope, Gemini Observatory, Thirty Meter Telescope, Large Binocular Telescope Observatory, Large Synoptic Survey Telescope Corporation, and the Giant Magellan Telescope Organization. He served for two years as chair of the Astronomy and Astrophysics Advisory Committee, which advises the NSF, NASA, and DOE on selected issues within the fields of astronomy and astrophysics that are of mutual interest and concern to the agencies.
