“No Research Without Action, No Action Without Research”
Kurt Lewin (1890-1947)
I am Marie‑Rachelle Narcisse, Ph.D., MSc, CHCQM, FABQAURP, a behavioral sleep medicine researcher with a strong commitment to advancing public health and health equity. My research applies rigorous quantitative methods to examine the structural and social determinants of sleep health across the life course. I am also interested in understanding how the oral microbiome influences population health in the United States.
My work focuses on health and healthcare disparities, access to care, and the ways systemic and structural forces shape health outcomes at the population level. Through a multidisciplinary lens, I aim to generate actionable, policy‑relevant insights that improve health trajectories, particularly for underserved and marginalized communities.
I have advanced training in econometrics, biostatistics, system dynamics modeling, and agent‑based modeling, and my research experience spans the translational continuum—from behavioral economics and clinical research to community‑engaged research and implementation science. I earned my Ph.D. in Public Health from the University of Montreal, hold graduate training in economics, completed a Postgraduate Certificate in Clinical Research at Harvard T.H. Chan School of Public Health, and earned an MSc in Sleep Medicine from the University of Oxford.
I am affiliated with the Warren Alpert Medical School of Brown University and serve as a Research Scientist at Bradley Hospital’s COBRE Center for Sleep and Circadian Rhythms in Child and Adolescent Mental Health. My work has been featured in Forbes, National Geographic, and U.S. News & World Report. I also serve as a journal editor and editorial advisory board member in the field of sleep and public health research.
