Anastasia Stellato is an Assistant Professor in Companion Animal Science at Texas Tech University. Dr. Stellato earned her PhD in Epidemiology, in the Ontario Veterinary College Companion Animal Behavior and Welfare lab.

She is the PI of the TTU Human-Animal Interaction Lab, where they use epidemiological methods to study companion animal welfare. Dr. Stellato's research focuses on improving our interactions with companion animals. Broadly, she has three main areas of focus: 1) improving canine welfare in the veterinary clinic, 2) mitigating companion animal stress within shelter, and 3) examining human-animal interactions during routine handling and other practices, with a focus on exploring the influence of low-stress handling.

Her research program aims to evaluate the impact of human-animal interactions on the behavior and welfare of companion animals, and to identify ways to prevent and reduce animal stress. Her research will investigate behavioral and physiological animal welfare indicators, the human-animal bond, and mental wellness of humans to improve the human-animal relationship within various applied environments, including veterinary clinics and animal shelters.
