Derek Haley

Steering Committee Member, Campbell Centre for the Study of Animal Welfare   |   Associate Professor   |   MSc (Guelph), PhD (Saskatchewan)


Dr. Haley leads a research program in applied ethology (animal behaviour) and animal welfare science, and he teaches graduate, undergraduate, and veterinary students about these subjects. The goals of his work are to advance our knowledge and understanding of the behavioural biology of farm animals (especially beef and dairy cattle), and to help us improve the ways we handle, manage, and care for them. This in turn will allow us to improve animal health, well-being, and productivity, and enhance our ability to use animal behaviour to answer questions about what animals experience.
