Director, Rodent Clinical Programs, Research Animal Resources, Johns Hopkins

Associate Professor of Molecular and Comparative Pathobiology

Expertise: Infectious Diseases

Research Interests: Impact of environmental factors on research; Rodent infectious disease epidemiology, including TMEV, pinworms and Helicobacter sp. more


Dr. Julie Watson is an associate professor of molecular and comparative pathobiology at the Johns Hopkins University School of Medicine. She serves as the Director of the Research Animal Resources Rodent Clinical Program, and the Director of Clinical Laboratory Animal Medicine Training Program for veterinarians.

Dr. Watson conducts research on the epidemiology of rodent diseases and the impact of environmental variation on animal research.

Dr. Watson is in charge of the clinical training program for veterinarians who wish to become specialists in the field of laboratory animal medicine.  

She devises and implements the strategies for surveying rodent colonies at Johns Hopkins for disease, maintains rodents free of compromising inter-current infections, and investigates and eliminates disease outbreaks. Her laboratory provides diagnostic and technical support for rodent research at JHU and her office is responsible for importing and exporting rodents for collaborative research.

Dr. Watson received her veterinary degree from the University of Cambridge (UK) in 1980. She worked for several years in private practice before moving to the United States in 1985 and completing a fellowship in comparative medicine at Johns Hopkins. She then worked as Attending Veterinarian, Arts and Sciences, at the University of Pennsylvania for 5 years, becoming an American College of Laboratory Animal Medicine diplomate in 1990. From 1995 to 2002, she ran her own business helping institutions to develop their animal care and use programs and gain AAALAC accreditation. In 2002, she returned to Johns Hopkins as a faculty member. more

Research Summary

Dr. Watson investigates variables in the environment that can negatively affect research outcomes, the epidemiology of rodent parasites and new environmental enrichment strategies.

Current projects include evaluating rack testing for rodent parasites by PCR as an alternative to sentinel testing and investigating the immunological basis for mouse immunity to fur mites.
