Dr. Luke Clark is a Professor in the Department of Psychology and Director of the Centre for Gambling Research at UBC. The Centre was established in 2014 with funding from the Province of British Columbia government and the British Columbia Lottery Corporation.
His current research focuses on 3 main questions: i) how do the psychological features of specific gambling products (e.g. modern slot machines) relate to gambling harms? ii) how do biological and psychological traits create vulnerability to disordered gambling? iii) how can behavioural data from online gambling be used to identify at-risk individuals?
He is an Assistant Editor for two of the leading journals in the field, Addiction and International Gambling Studies.
Research interests include cognitive and neurobiological mechanisms involved in gambling behaviour and disordered gambling, with a particular focus on cognitive distortions including the illusion of control and the gambler’s fallacy; behavioural addictions; the neural, neurochemical and psychophysiological basis of human decision-making.
