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. She teaches primarily in VMP 5265 Parasitology and in the One Health on-line program.
