PhD, King's College, University of Cambridge, 1980
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.
Hogan's 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.
His current work is developing a theory of a proposed new phenomenon, which he calls "holographic noise", a fundamental, universal uncertainty in the fabric of spacetime, due to a fundamental bandwidth of reality at the Planck frequency, 1044 bits per second. With colleagues at Fermilab, the University of Chicago, and other institutions, he was developing an experiment, the Fermilab Holometer, to measure this effect.
