After obtaining degrees from the universities of Guelph, Alberta and Saskatchewan, Dr. Gonyou has served as a professor at the University of Illinois and as Research Scientist in ethology at the Prairie Swine Centre. His research has included all major agricultural animals, but is now focused on the social behaviour of pigs and their interaction with resources within their pen. His recent projects include feeder and waterer design, group housing of sows, gestation stall design, space allowance for pigs, large groups for grow-finish pigs, and pig handling. He has served as President of the International Society for Applied Ethology, editor-in-chief for the scientific journal Applied Animal Behaviour Science, and on committees for the Canadian Pork Council and National Pork Board (US).
