Joseph T. Newsome, DVM
Research Associate Professor of Pathology

Dr. Newsome is Associate Professor of Pathology and the Director of the Division of Laboratory Animal Resources (DLAR), Health Sciences and also the Director for the UPMC Hillman Cancer Center Animal Facility shared resource. He has over 31 years of coordinating preclinical and translational research with the use of animal models. He is a central reference resource for the Division of Laboratory Animal Resources and the University concerning collaborative integration between disparate research groups using a wide range of animal models. Knowledge of available programmatic animal based resources such as animal modeling, facility design and management, clinical study design, imaging, veterinary immunopathology, and veterinary surgery are key supports to the institution. This oversight of research using animal models occurs at the various branches of the University including the Six Schools of the Health Sciences, and Schools of the Arts and Sciences. His support extends but is not limited to animal model research at the Hillman Cancer Center being a member of the Cancer Virology and Colon Cancer research teams, McGowan Institute of Regenerative Medicine, the Starzl Transplant Institute, to name a few.
