Alison Gemmill is a demographer and epidemiologist with expertise in maternal, perinatal, and reproductive health and fertility. Her current research involves four overlapping arms: the demography of fertility and reproductive outcomes; environmental and macrosocial stressors and perinatal health; stress and health throughout the lifespan; and estimating maternal mortality and maternal cause of death.

Her previous and current work on U.S. fertility examines fertility intention dynamics, state-level variation in fertility responses to the Great Recession, and explanations for the unprecedented, recent decline in non-marital fertility. Her other recent research studies how women’s risk preferences and perceptions impact contraceptive use behavior, the relationship between macrosocial stressors and perinatal health, and global and regional patterns of maternal health indicators. She is a former NICHD and NIA predoctoral fellow in demography and has published lead-authored and collaborative work in journals such as Demography, Proceedings of the National Academy of Sciences, Lancet, Lancet Global Health, Population and Development Review, and JAMA Network Open.
