Craig Hogan is a Professor of Astronomy and Physics at the University of Chicago and he is the director of the Fermilab Center for Particle Astrophysics. He is known for his theory of "holographic noise", which holds that holographic principle may imply quantum fluctuations in spatial position that would lead to apparent background noise or holographic noise measurable at gravitational wave detectors, in particular GEO 600. He was a member of the international High-z Supernova Search Team which co-discovered dark energy in 1998.
