Cole Miller is a professor in the Astronomy department whose work focuses on black holes and neutron stars, both to understand those objects and to use them as probes of extreme physical regimes. He received his doctorate in physics from the California Institute of Technology, then had postdoctoral stints at the University of Illinois and the University of Chicago before joining Maryland in 1999.
