The Department of Psychology and Neuroscience and Faculty of Science are deeply saddened by the passing of Dr. Sean P. Barrett on June 13, 2024, at the age of 50. Sean was a cherished member of our department for 19 years. He was an active and productive scientist. He was also a dedicated mentor and instructor devoted to ensuring the success of his students and was deeply committed to advancing our understanding of the factors that contribute to addictive behaviours. Our department mourns the loss of Sean, and our thoughts and sympathies go out to Sean’s family, friends, colleagues, and students. He is deeply missed.

Dr. Sean Barrett [BA (St.FX), PhD (McGill)] was a professor in the departments of Psychology & Neuroscience and Psychiatry at Dalhousie University, as well as a Registered Psychologist in the province of Nova Scotia.
Dr. Barrett's research was in the areas of addiction, polysubstance use, alcohol, tobacco, cannabis, gambling, psychiatric comorbidity, and human psychopharmacology. Dr. Barrett’s research aimed to elucidate how various pharmacological & non-pharmacological factors contribute to different addictive behaviours, as well as to determine the extent to which there are individual differences in these factors."
