Dr. Langdon's research is centered on two overlapping areas: 1) elucidating the interplay of mood/anxiety-based processes and co-occurring substance use disorders through experimental paradigms, and 2) developing specialized intervention programs designed to target these malleable risk factors to improve treatment outcomes for individuals with co-occurring mood/anxiety and substance use disorders, particularly through digital health platforms. Past work has examined tobacco use among psychiatrically vulnerable populations. More recently, her work has focused on designing and testing novel strategies, delivered through digital health, to intervene with Opioid Use Disorder.
