Roger is passionate about the potential of digital technologies for the advancement of behavioral science, and the development of cost-effective and higher-reaching behavioral interventions. He directs the 'Access to Behavioral Health for All' (ABHA) lab, at Duke's Center for Addition Science and Technology. The focus of the ABHA lab is to ideate, develop, and test digital behavioral health interventions for underserved populations, such as individuals who experience persistent mental health symptoms, addiction, or chronic pain. It specializes in: (1) designing digital tools to foster behavioral health and psychological resilience, and (2) the application of rigorous strategies to evaluate them. Using a multi-method approach that includes the use of user-centered design research, small-n experimental designs, and clinical trials methodology, the lab combines data from qualitative interviews, app background analytics, clinical interviews, and self-reports to better understand the behavior of digital health users.
