Joy E. Tomlinson, DVM, PhD, DACVIM (LAIM)
Tomlinson, is an Assistant Professor of Large Animal Medicine in the Department of Clinical Studies – New Bolton Center. She received her degrees in biological and environmental engineering, veterinary medicine, and biomedical and biological sciences from Cornell University. Her research focuses on equine viral hepatitis, including the pathogens equine parvovirus-hepatitis (EqPV-H) and equine hepacivirus (EqHV). Her seminal work in this area has defined new diseases, resulting in federal regulations to prevent disease transmission.

Viral pathogenesis in horses. Specifically, my research program is focusing on recently discovered liver viruses in equids including Equine parvovirus-hepatitis, Equine hepacivirus, and Equid hepadnavirus. We are characterizing the routes of transmission, disease associations, and pathogenesis of each virus with a goal to develop treatment and prevention approaches.
