Craig J. Hogan
KICP Senior member
PhD, University of Cambridge, 1980
Craig Hogan is Director of the Fermilab Center for Particle Astrophysics, where he is also a member of the scientific staff and the Theoretical Astrophysics Group. He is also a professor at the University of Chicago, where he is on the faculty of the Department of Astronomy and Astrophysics, the Enrico Fermi Institute, and the Kavli Institute for Cosmological Physics.
Hogan earned his doctorate at the University of Cambridge in 1980. After postdocs at Chicago, Caltech and Cambridge, he joined the faculty of Steward Observatory at the University of Arizona in 1985. In 1990 he moved to the Physics and Astronomy Departments at the University of Washington in Seattle, where in time he served as department Chair, divisional Dean, and Vice Provost for Research. He moved to Chicago in 2008.
Hoganís theoretical work has encompassed many areas of astrophysical cosmology: the origin of the elements, cosmic phase transitions and defects, magnetic fields, background radiation, cosmic reionization, gravitational lensing, cosmic structure and dark matter, global cosmological parameters, and gravitational waves. He was a co-founder of the Large Synoptic Survey Telescope Corporation, and is a US member of the LISA International Science team, which is planning a gravitational wave observatory in space. His research has been recognized by prizes including an Alexander von Humboldt Research Award, and the Gruber Cosmology Prize, awarded to the High-z Supernova Search Team for the co-discovery of cosmic Dark Energy.
In his current work he is developing the theory of a proposed new phenomenon, which he calls "holographic noise", a fundamental, universal uncertainty in the fabric of spacetime, akin to pixelation in an imperfectly sampled digital audio file or video display. The theory may lead to the development of experiments that could allow a direct measurement of the minimum interval of time.Past Scientific Projects: Sloan Digital Sky Survey (SDSS)
