More Experts


Michael Dunbar (he/him) is a behavioral scientist at the RAND Corporation. His research examines the ways in which situational factors and policy environments influence patterns of health behaviors, like nicotine and tobacco use, as well as health service utilization. Dunbar's work employs a range of methodologies and study designs, including experimental research, semi-structured interviews, surveys, and ecological momentary assessment. His current studies focus on topics such as understanding the effects of tobacco advertising at retail point-of-sale on adolescent smoking susceptibility; examining longitudinal patterns of nicotine and cannabis vaping product use in young adults; and evaluating programs aimed at increasing access to behavioral health services in underserved populations. Dunbar received his Ph.D. in clinical and health psychology from the University of Pittsburgh.
