Kirsten Langdon, PhD, is a clinical psychologist and an Assistant Professor (Research) in the Department of Psychiatry and Human Behavior at The Warren Alpert Medical School of Brown University. Dr. Langdon is the founding Director of the IMPACT Lab, which focuses on developing and empirically testing personalized interventions aimed at improving traditional addiction treatment. Her program of 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 (e.g., ecological momentary assessment), and 2) developing specialized intervention programs designed to target these malleable risk factors to better support individuals with co-occurring mood/anxiety and substance use disorders.  As a scientist-practitioner, Dr. Langdon is committed to addressing mental health and addiction through innovative, evidence-based, interventions, particularly those delivered through digital health platforms.
