Craig Hogan has been appointed director of the Center for Particle Astrophysics at the Department of Energy’s Fermi National Accelerator Laboratory and as a professor of astronomy and astrophysics at the University of Chicago. Hogan, who wrote The Little Book of the Big Bang: A Cosmic Primer, is an astronomy and physics professor at the University of Washington and a member of the international High-z Supernova Search Team that in 1998 co-discovered dark energy, the mysterious force that works against gravity to accelerate the expansion of the universe. He is a member the Large Synoptic Survey Telescope and the Laser Interferometer Space Antenna (LISA), a proposed 8.4-meter telescope that will take images of faint astronomical objects, including exploding stars and potentially hazardous near-Earth asteroids. The satellite-based LISA mission will explore and measure the early universe using gravitational waves, predicted in Einstein’s theory of general relativity. Hogan is also studying techniques for probing the quantum nature of space-time in the laboratory. He has a bachelor’s degree in astronomy from Harvard University and a PhD in astronomy from King’s College at the University of Cambridge, England (1980), and was formerly an Enrico Fermi Fellow at the University of Chicago, a National Science Foundation Postdoctoral Fellow at Cambridge and a Bantrell Prize Fellow in Theoretical Astrophysics at the California Institute of Technology. He was also previously on the University of Arizona faculty.
