Richard O'Callaghan received the B.S. degree from the University of New Orleans (formerly known as LSU), New Orleans, La, USA, and then the MS and Ph.D. degrees in microbiology from the University of Mississippi Medical Center (UMC), USA. Later, he became a Postdoc and an Instructor at the Department of Biochemistry at the University of Alberta, Canada. In 1972, he became an Assistant Professor of microbiology at the Louisiana State University Medical Center in New Orleans (LSUMC) and moved up to a Full Professor prior to leaving in 2005. Since 2005, he has been a Professor and the Chairman of the Microbiology Department at UMC. He has done various researches during the years of his career. He has published studies on pseudomonas bacteriophage, equine herpesvirus, R17 bacteriophage, M13 bacteriophage, sex pili of E. coli, antibiotic therapy for nosocomial infections caused by drug resistant Klebsiella, influenza C virus, and, for the past twenty plus years, bacterial keratitis. The keratitis research has included virulence studies of Pseudomonas, Staphylococcus, and pneumococcus. For these and other ocular pathogens (e.g., Serratia and Mycobacterium), he has studied the effectiveness of various antibiotics, particularly fluoroquinolones. He has intensely studied two antibiotics (i.e., Ciloxan and Vigamox), which became commonly used drugs for treating or preventing ocular infections.
