Laboratory Animal Medicine

Lab animal veterinarians in RAR assure the welfare of all experimental animals at JHU, provide their clinical care, and assist with experimental design and procedures.

Molecular and Comparative Pathobiology faculty, fellows, and residents trained in Laboratory Animal Medicine, participate actively in Research Animal Resources (RAR) to support clinical care of research animals at the Johns Hopkins University. Clinical veterinarians on call are responsible for all medical or surgical cases. In addition to clinical service, these veterinarians conduct and collaborate in research within and outside the department.


MCP comparative medicine faculty are specialty board certified in the American College of Laboratory Animal Medicine (ACLAM). They support, conduct and collaborate in translational biomedical science at JHU.
