Gbur got his B.A. in physics from the University of Chicago (1993), his M.A. in physics from the University of Rochester (1996), and his Ph.D. from the University of Rochester (2001) under Emil Wolf for the thesis "Nonradiating sources and the inverse source problem".[2][3]
In September 2020, The Optical Society elected Gbur a Fellow, in recognition of "contributions to coherence theory, singular optics, and the intersection of these disciplines".[8]
Gbur maintains an active interest in the history of science. He founded and co-moderated a blog carnival, The Giant's Shoulders, which focused on the history of science and ran from 2008 to 2014.[9][10] He maintains a popular science weblog, Skulls in the Stars, that seeks to elucidate science and its history for the public.[11] Two of his blog posts have been included in "best of online science" books.[12][13] He has contributed to Science Blogging: The Essential Guide.[14]
Gbur has written a number of scholarly introductions to classic horror fiction, including John Blackburn's Broken Boy,[16]Nothing but the Night,The Flame and the Wind,Bury Him Darkly,The Face of the Lion,The Cyclops Goblet, and Our Lady of Pain.[17] He also wrote an introduction to Archie Roy's Devil in the Darkness.[18]
