A member of the faculty since 1995, Prof. Weinberg studies the large scale structure of the universe, dark energy and dark matter, the formation and evolution of galaxies and quasars, and the intergalactic medium (IGM). He is well-known for his development of “halo occupation” methods to connect observed galaxy clustering to underlying dark matter structure, for theoretical modeling and cosmological applications of the Lyman-alpha forest, and for numerical simulation studies of the mechanisms of galaxy growth. Prof. Weinberg was the Project Spokesperson of SDSS–II and the Project Scientist of SDSS–III, and he remains closely involved with SDSS-IV and SDSS-V .  He is a member of the Dark Energy Survey (DES) and the Dark Energy Spectroscopic Instrument (DESI) Collaboration, and he has served on the science definition teams and formulation science working group of the Wide Field Infrared Survey Telescope (WFIRST) mission for the past decade.  His contributions include a book-length review of Observational Probes of Cosmic Acceleration, examining the observational techniques and analysis methods that underpin dark energy experiments, co-authored with CCAPP colleague Chris Hirata, former CCAPP Fellows Eduardo Rozo and Michael Mortonson, and luminaries Daniel Eisenstein and Adam Riess.   His recognitions include the OSU Distinguished Scholar Award (2006), the Henry L. Cox Professorship (2013-2018), the American Astronomical Society's Lancelot M. Berkeley New York Community Trust Prize (2015), and a Distinguished University Professorship (2017).  He has been chair of the Astronomy Department since 2015.
