Jennifer K. Ketzis, BS, MS, PhD
Dr. Jennifer Ketzis received her PhD from Cornell University, where she focused on international livestock production and the use of medicinal plants to control Haemonchus contortus in goats. She then took a position at Novartis Animal Health in Switzerland working on the development of natural based products and endo- and ecto-parasiticides. In 2005, as a Senior Scientist, she established a parasitology laboratory at Charles River Laboratories, Ireland, where she worked with several pharmaceutical companies designing and managing GLP and GCP ecto- and endo-parasite efficacy studies. In 2012, Dr. Ketzis joined Ross University School of Veterinary Medicine. From 2017 to 2022, she served as the coordinator of the MSc and Certificate One Health Program. She currently is the Chair of the RUSVM IACUC and serves on the Executive Committee of the American Association of Veterinary Parasitologists. She teaches primarily in VMP 5265 Parasitology, VMP 5252, 5352 and 5452 Clinical Reasoning Skills I-III, and in the One Health on-line program.
