Glenn Piner

Physics and Astronomy
Whittier College
United States of America


Professor Glenn Piner received his Ph.D. in astronomy from the University of Maryland at College Park in 1998. He did his Ph.D. research with the gamma-ray astronomy group at NASA Goddard Space Flight Center in Greenbelt, MD, and with the VLBI group at the U.S. Naval Observatory in Washington D.C., on radio properties of quasars detected by the Compton Gamma-Ray Observatory. After graduate school, Piner spent two years as a Caltech Postdoctoral Scholar at the NASA Jet Propulsion Laboratory in Pasadena, working on space-based radio astronomy. During this time he was an active collaborator on the Japanese VSOP space-based radio telescope. Piner came to Whittier College in 2000. At Whittier, he teaches the full range of physics classes, along with a year-long astronomy sequence designed primarily for non-majors. He maintains an active program in quasar research involving undergraduate physics majors, using data from the National Radio Astronomy Observatory’s Very Long Baseline Array (VLBA) of radio telescopes. This research program has been supported by grants from NASA and the National Science Foundation.
