Comparative Pathology in Translational Science

Faculty, fellows, and residents in Comparative Pathology identify and investigate naturally occurring disease in our institutional animal colonies and collaborate in diverse research areas. Pathologists work with clinical veterinarians to diagnose conditions identified via routine colony health surveillance, and from our clinical veterinarians and investigators.  Pathologists perform complete gross and histopathologic examinations of animals or biopsies.

Every case is formally reviewed by an ACVP board-certified veterinary pathologist. Final reports are sent to the investigator and entered into the computerized Comparative Pathology database: more than 68,000 archived cases are available at Johns Hopkins for research and review.

  • Our Comparative Pathology faculty also provide diagnostic support and conduct research collaborations with a number of regional institutions, including the National Aquarium, the National Zoo and the Maryland Zoo in Baltimore, all of which share a common interest in Comparative Pathology.

Collaboration and Consultation

Consultation and collaboration for experimental design and pathology is available though Dr. Cory Brayton and the Phenotyping Core, or by contacting other comparative pathology faculty. Pathology consulting and research collaborations through the phenotyping core are customized to the research project and model, can include animal model selection, experimental design, test development, procedural training, specialized testing and pathology procedures, training, reporting, imaging, morphometry, manuscript and grant preparation, and involves relevant experts within and beyond our department.


MCP anatomic pathology faculty are specialty board certified in the American College of Veterinary Pathologists (ACVP). They support, conduct and collaborate in translational biomedical science at JHU.
