Experiences & Accomplishments
Alison Gemmill is a demographer and perinatal epidemiologist with primary interests in maternal, women’s, and perinatal health; sexual and reproductive health and fertility; and life course epidemiology. Much of her research considers how maternal exposures to structural and environmental stressors, which are distributed unequally across the population, affect pregnancy outcomes such as preterm birth, fetal loss, and maternal morbidity, and how such exposures exacerbate health disparities. She is also an expert on US fertility patterns and trends and has published on fertility intention dynamics, fertility responses to population shocks such as the COVID-19 pandemic, explanations for declining birth rates in the US, and childlessness.
Dr. Gemmill is currently a co-Investigator on two NICHD R01 grants, as well as the former Principal Investigator of a Robert Wood Johnson grant and several internally funded pilot projects. These funded projects include topics such as: pregnancy-associated mortality and morbidity in the U.S.; the relationship between maternal stress and adverse pregnancy outcomes; how state-level policy environments impact maternal and women’s health; and the long-term impacts of pregnancy on women’s cardiovascular and cognitive health. She also currently serves as Technical Advisor to the World Health Organization on maternal mortality measurement.
