John Stocke is a Professor of Astrophysics and Space Astronomy at the University of Colorado at Boulder. His teaching interests include Astronomical Observations and Instrumentation, General Astronomy, and Ancient Astronomy. His research interests include the evolution of quasars and BL Lacertae objects; the structure of extended radio galaxies; the environment of active galaxies and its effect in the active nucleus of these galaxies; isolated galaxies; x-ray emission from quasars, Seyferts, BL Lac objects, and normal stars; and Herbig-Haro objects as interstellar shock fronts and tracers of bipolar outflows from young stars.

Professor Stocke is an extragalactic observer who uses all manner of space-based and ground-based telescopes to study normal and active galaxies, clusters of galaxies, and intergalactic gas. His primary interests have been in using the Hubble Space Telescope’s spectrographs to discover, inventory, and study intergalactic gas clouds and to figure out their relationship to galaxies. This study has led to the first-ever detection of matter in voids. Professor Stocke is a member of the science team building the COS Colorado University and Ball Aerospace.
