Piper Meigs Treuting received her Doctorate of Veterinary Medicine from Louisiana State University in 1996 and began a post-doctoral fellowship in the UW Department of Comparative Medicine the same year. After receiving her Master of Science she joined the DCM faculty in the position of Chief of the Rodent Health Monitoring Program. Dr. Treuting received board certification in veterinary anatomic pathology by the American College of Veterinary Pathologists in September of 2001. Dr. Treuting serves as Chief of Comparative Pathology Program and services, directs UW Veterinary Diagnostic Laboratory, and co-directs the Histology and Imaging Core (HIC). Dr. Treuting is the consulting comparative pathologist for the HIC.

Research, Service, and Training Interests

Dr. Treuting’s overarching research interest is focused on the pathology of genetically modified rodents and the use of animal models in translational study of human disease. She has extensive experience in the pathology of animal models of human diseases, discovery and preclinical research, and collaborates with diverse research groups.

Dr. Treuting is an Editor-in-Chief, contributing author and photo editor of Comparative Anatomy and Histology: A Mouse and Human Atlas. The second edition will be published in June 2017.  She is a guest Co-Editor-in-Chief for Veterinary Pathology’s special topic issue on Aging. She is the editor of book reviews for Veterinary Pathology.

Dr. Treuting coordinates the pathology coursework, rounds, and rotations offered by the Department of Comparative Medicine (CMED 514, 512, 590; Comparative Pathology Rounds). She co-coordinates the Biology and Diseases of Laboratory Animal course series (CMED 520/530 521/531), and the Biology of the Mouse (CMED 407). Dr. Treuting also trains and mentors select residents interested in achieving ACVP board certification. She is member of the coordinating faculty for the Jackson Laboratories Annual Workshops on the Pathology of Mouse Models for Human Disease.
