Sunni L. Mumford, PhD

Based in Bethesda, Maryland, Dr. Sunni L. Mumford is a senior epidemiologist and PCOS researcher whose work has shaped the national scientific understanding of polycystic ovary syndrome. Now at the University of Pennsylvania, she previously led population-level PCOS and fertility studies at the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

Dr. Mumford's research examines how PCOS affects women across diverse populations, with a focus on fertility, environmental influences on reproductive health, and the factors that predict outcomes for women with polycystic ovary syndrome. Her NIH-funded studies have provided critical data that informs clinical guidelines and public health approaches to PCOS nationwide.

For patients and clinicians in the Bethesda and greater Washington, DC area, Dr. Mumford represents the research frontier of PCOS science. While her primary role is as a researcher rather than a clinician, her contributions to understanding polycystic ovary syndrome — its prevalence, causes, and consequences — directly benefit the millions of women living with the condition. Her work at the intersection of epidemiology and reproductive health continues to expand the evidence base that guides PCOS specialists across the country.
