Piper M. Treuting, D.V.M., M.S.
Associate Professor

Department of Comparative Medicine
School of Medicine
University of Washington
Seattle, WA

P: 616-6725

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 Services and co-directs UW Veterinary Diagnostic Laboratory and 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 mice and the use of mouse models in translational study of human disease. Her research areas center on mouse models in aging, inflammation and cancer.

Dr. Treuting and Dr. Suzy Dintzis (Department of Pathology) are the Editors in Chief and contributing authors of Comparative Anatomy and Histology: A Mouse and Human Atlas. This new reference text will be published in Nov. 2011. The atlas is aimed at the new mouse investigator as well as medical and veterinary pathologists who need to expand their knowledge base into comparative anatomy and histology. It guides the reader through normal mouse anatomy and histology using direct comparison to the human. The side by side comparison of mouse and human tissues highlight the unique biology of the mouse, which has great impact on the validation of mouse models of human disease.

Dr. Treuting coordinates the pathology coursework, rounds and rotations offered by the Department of Comparative Medicine (CMED 514, 512, 590; Thursday AFIP sessions). 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.
