Dr. Ruple’s primary research interest lies in the area of “One Health,” the intersection of human, animal, and environmental health. Her diverse and extensive experiences lend themselves to her One Health research in both comparative/translational medicine and infectious diseases that occur at the human-animal interface. Dr. Ruple’s comparative medicine research is primarily focused on the companion dog as a model for health and disease in human populations. This model system has many advantages over other animal models due to the fact that companion dogs share our environment in addition to a large amount of shared ancestral genetic sequence. Dogs also share much of the disease burden seen in human populations, especially in regards to cancer outcomes, and can be used as a model for healthy aging.
Dr. Ruple is also an expert in infectious diseases, biosecurity, and hospital infection control. Her veterinary background is especially important in this research area given recent estimates that up to 75% of emerging infectious diseases in human populations are zoonotic, meaning they arise from animal populations. Several of her published works on hospital infection control and biosecurity have received awards from international organizations such as the International Society for Disease Surveillance.
Dr. Ruple is a member of the Purdue Comparative Oncology Program and Purdue Center for Cancer Research, acts as the Advisor to the Purdue One Health Club, and serves as the Chair of the Senate’s Equity and Diversity Committee.
