Research Interests

Dr. Osborn's research interests are in observational astronomy. Current research projects involve photometric studies of variable stars in globular clusters. He is also involved in national and international efforts to preserve astronomical photographic plates. Osborn is the author or co-author of over 60 refereed scientific papers plus various book articles, research notes, abstracts, and book reviews. His research has involved observations with the Hubble Space Telescope as well as at ground-based observatories in the U.S. and abroad.
