Laboratory of Pathology & Toxicology

The faculty members in the Laboratory of Pathology and Toxicology have a wide range of interests in diagnostic anatomic, clinical, and toxicological pathology, and clinical and basic research. Supporting the bustling diagnostic services, cases provide a rich resource for generating hypotheses and investigating clinically relevant disease in veterinary and human medicine.  The laboratory is also home to Avian Medicine & Pathology, which provides diagnostic service to the state and regional poultry agricultural industry.Penn Vet Clinical pathology faculty
