Veterinary Pathologist/ Pathology Unit Head
Animal Services (Pathology), Wisconsin National Primate Research Center
Aligned research focus
Comparative pathology, aging, cancer, infectious diseases, and neurodegenerative diseases.
Organ system/disease focus
Infectious diaseases, aging, cancer/neoplasia
My research interests include comparative pathology of nonhuman primates (NHP), wildlife and domestic species; non-human primate models of human disease; and mechanisms of infectious and non-infectious disease. I collaborate with investigators to plan research protocols investigating a variety of research interests including cervical anatomy during pregnancy, spontaneous neoplasia, infectious diseases such as SIV/HIV and listeria, Parkinson’s disease, as well as pathologies associated with diet and aging.
The WNPRC is committed to ensuring maximum scientific use of animals through the Nonhuman Primate Biological Materials Distribution program, which allows distribution of biological samples from animals assigned to short term minimally invasive protocols and animals undergoing terminal procedures.
