Our research group studies self-injurious behaviors, including non-suicidal self-injury (NSSI) and suicidality. We investigate the nature and functions of NSSI using a range of paradigms including experience sampling, experimental paradigms, questionnaire studies, and virtual reality simulations. As Wyoming has one of the highest suicide rates in the country, we are also interested in furthering our understanding of the high rates of suicide in the Mountain West region.
