Adjunct Associate Professor
In the Newberry laboratory, our research concerns the behavior
and well-being of animals, with a focus on environmental enrichment,
social behavior, and human-animal interactions. We use behavioral
measures such as vocalizations, exploration, and play to assess
affective states. We also investigate animal preferences, motivations,
and decision-making to gain insights into the inner subjective lives of
animals. Our goal is to develop methods for improving animal care
through environmental enrichment, social grouping strategies, handling
and training methods, and housing design. We also seek methods to
prevent and control abnormal behavior. We work with a variety of species
in agricultural, laboratory, and zoo settings, as well as with companion
A current focus is identifying factors contributing to the
development and expression of injurious behavior in animals. We are
characterizing the behavioral, morphological and neurobiological
characteristics of aggressive and cannibalistic individuals with the aim
of understanding the mechanisms underlying these behaviors. The role of
individual and social learning in the spread of injurious behaviors is
also under investigation. This information is used to develop humane
animal management systems that reduce the risk of animal injury and
promote animal well-being.
Ruth C. Newberry, Associate Professor, received her B.Sc. in biology and
her Ph.D. in agriculture from the University of Edinburgh in 1979 and
1983, respectively. She held a fellowship from the Natural Sciences and
Engineering Research Council of Canada at the Pacific Agri-Food Research
Centre in Agassiz, British Columbia from 1983-1985. She was subsequently
employed there as a research scientist until 1996, when she joined the
faculty of the Departments of IPN and Animal Sciences. She was the first
faculty member appointed in the Center for the Study of Animal
She is a Past President of the International Society for Applied
and is currently a scientific advisor to various groups addressing
issues of farm animal well-being.
