My primary area of research focus is on behavioral addictions. Specifically, I focus on addictions facilitated by technology: (a) internet gaming disorder, (b) social media addiction, and (c) problematic pornography use. I am interested in examining the prevalence, correlates, effects, and interventions of these addictions. Finally, I supervise both graduate and undergraduate students, and work with them to publish their thesis. The full text of the article can be obtained by clicking on the title. *Student Co-Author
