Laboratory Members

Principal Investigator

Dr. Murray began investigating the interoceptive stimulus properties of drugs of abuse as a graduate student in Prof Rick Bevins' Behavioral Neuropharmacology laboratory at the University of Nebraska-Lincoln in the United States. Following earning her PhD in 2009, she joined Prof Barry Everitt as a post-doctoral research associate at the University of Cambridge in England. There, she used novel models of drug dependence to assess particular theories of addiction. She was also an official fellow of Murray Edwards College and directed studies for their psychology students. In 2016, Dr. Murray returned to North America as a research assistant professor at UNL with Prof Bevins' research group before beginning her post as an assistant professor in the Department of Psychology at the University of Guelph in 2018.
