I obtained my Ph.D. in Biopsychology from the University of British Columbia in 1982, under the supervision of Dr. Don Wilkie. I then spent two years at UCSD on an NSERC postdoctoral fellowship, followed by four years as an Assistant Professor in the Department of Psychology at Dalhousie University. I joined the Department of Psychology at the University of Alberta in 1987.

I am a member of the Comparative Cognition and Behaviour research group and the Biocognition Unit. My research investigates basic cognitive processes that are important for adaptive functioning in humans and other animals, such as navigation, decision-making, and object recognition. Much of my research is with pigeons, but I also investigates cognitive processes in organisms ranging from ants to humans.

I was previously president of the Comparative Cognition Society.
