D.V.M., 1974, University of Missouri College of Veterinary Medicine, Columbia, MO

Dr. Elkins obtained his D.V.M. from the University of Missouri College of Veterinary Medicine in 1974. He then completed a one-year internship in large animal surgery at the University of California, School of Veterinary Medicine, Veterinary Medical Teaching Hospital. Following several years of clinical practice in California, he completed a residency in comparative pathology at the U.S. Army Medical Research Institute of Infectious Diseases, Ft. Detrick, Maryland. He joined the NIAID Division of Intramural Research (DIR), Laboratory of Infectious Diseases (LID), Immunodeficiency Viruses Section, as a senior staff laboratory animal veterinarian in 1992 and was promoted to head of the Experimental Primate Virology Section, LID, in 1997. Dr. Elkins was appointed DIR Associate Director for Nonhuman Primate Research in 2000 and DIR Associate Director for Laboratory Animal Resources and Animal Program Director in December 2001. He became specialty board-certified by the American College of Laboratory Animal Medicine in 1996.
