Hannah Posluszny

Hannah Posluszny, MSPH, RDN, is a PhD student in the Nutrition and Health Sciences program at Emory University. She studies the biological mechanisms linking early-life nutrition to adult health using data from the Institute of Nutrition of Central America and Panama (INCAP) Nutrition Supplementation Trial Cohort in Guatemala. Her work integrates epigenetics, body composition assessment, and Mendelian randomization to understand how early nutritional environments shape health across the life course. As a registered dietitian by training, she aims to bridge biological, epidemiologic, and translational perspectives to inform public health strategies that support healthier aging. Hannah is mentored by Dr. Aryeh Stein.
