ULAM Pathology Core, Unit for Laboratory Animal Medicine (ULAM)


Dr. Bergin has dual board-certification in laboratory animal medicine and veterinary pathology. She joined the ULAM faculty in December of 2008 and holds a dual diagnostic service and research position. As Director of the Unit for Laboratory Animal Medicine (ULAM) Pathology Core, Dr. Bergin oversees a team of experienced faculty and staff who provide histology, hematology/clinical chemistry, and pathology services in support of non-clinical research and the veterinary care program at the University of Michigan. She also teaches Toxicologic Pathology (EHS616/717) in the Department of Environmental Health Sciences in the School of Public Health.


Dr. Bergin’s principal interests are in toxicologic pathology and infectious diseases, particularly in mucosal systems such as the gastrointestinal and reproductive tracts. Previous or ongoing projects include Helicobacter pylori gastric carcinogenesis in a Mongolian gerbil model, mouse models of Clostridium difficile colitis, reproductive tract pathology in non-human primate and rodent models, and evaluation of the effects of dietary metals on inflammatory/carcinogenesis pathways in the gut.

She welcomes collaborative inquiries from investigators needing research pathology support, particularly in the areas of gastrointestinal and reproductive animal models of human disease.
