More Experts


Michael Stephen Dunbar 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, particularly nicotine and tobacco use. His work employs a range of methodologies and study designs, including experimental research, surveys, program evaluation, and ecological momentary assessment. His current studies span a range of populations (e.g., adolescents, adults, low-income populations, sexual and gender minorities), and focus on topics including alternative tobacco product use, barriers to accessing health care, and efforts to improve utilization of behavioral health services in underserved populations. Dunbar received his Ph.D. in clinical and health psychology from the University of Pittsburgh.
