    Dr. Rita Hamad is a social epidemiologist and family physician in the Philip R. Lee Institute for Health Policy Studies and the Department of Family & Community Medicine at UCSF. As the director of the Social Policies for Health Equity Research Program (https://sphere.ucsf.edu), her research focuses on the pathways linking poverty and education with health disparities across the life course. In particular, she studies the health effects of social and economic policies using interdisciplinary quasi-experimental methods. She also investigates the mechanisms through which adverse socioeconomic conditions get "under the skin" to cause disease.

    Dr. Hamad is the Associate Director of the Center for Health Equity. She is also a member of the steering committee of the UCSF Population Health Data Initiative, serving as the Faculty Lead for the development of data infrastructure to advance population health research on campus. She serves as the Policy Lead of the UCSF Preterm Birth Initiative, spearheading an agenda to reduce disparities in preterm birth by addressing its upstream determinants. Dr. Hamad mentors trainees at all levels in population health research, and she supervises family medicine residents at the Family Health Center at San Francisco General Hospital. She also serves on the Communications Committee of the Interdisciplinary Association of Population Health Sciences.
