Samuel W. Stull, PhD
Research Scientist, Center for Technology and Behavioral Health
Dr. Samuel W. Stull is a Research Scientist at the Center for Technology and Behavioral Health at Dartmouth College. He is currently funded by a K01 Career Development Award from NIDA to develop and test the Humor and Addiction Recovery (HA!) app, a novel digital intervention designed to promote treatment engagement, enjoyment, and adaptive coping among adults in early recovery from opioid use disorder.
Dr. Stull’s program of research examines the role of positive mood states and enjoyable events in supporting addiction recovery on a daily basis, with a particular focus on how digital interventions can be designed to leverage these processes to improve outcomes. His work integrates innovative analytic methods to capture the dynamic and heterogeneous nature of daily recovery processes, including time-varying effect modeling and multilevel latent class analysis. In addition, he draws on adaptive intervention and micro-randomized trial approaches to inform the development and optimization of digital interventions like the HA! app.
Dr. Stull completed postdoctoral training at the Center for Technology and Behavioral Health under the mentorship of Drs. Lisa Marsch and Nicholas Jacobson. He received his PhD in Biobehavioral Health (emphasis in applied statistics) from Penn State University under the mentorship of Dr. Stephanie Lanza, during which he was awarded an NSF Graduate Research Fellowship and a NIDA NRSA F31 Predoctoral Fellowship. Prior to graduate school, he worked as a post-baccalaureate fellow at the NIDA Intramural Research Program under the mentorship of Drs. Kenzie Preston and David Epstein.
