Dr. Gilley's research aims to enhance lifelong health by optimizing nutrition during infancy and early childhood. Her investigations include the effects of fetal growth restriction on metabolic health and gut microbiome composition, early iron exposure's impact on infant gut microbiota and inflammation, predictors and modifiers of rapid infant weight gain, and sex differences in high-fat diet responses following intrauterine growth restriction. She has obtained principal investigator funding from the NIH K08 award (2025-2030), Colorado NORC Pilot and Feasibility Awards (2022, 2024), Colorado Children’s Health Research Institute, Ludeman Family Center for Women's Health Research (2021-2022), and others. Key publications encompass "Association of Maternal BMI and Rapid Infant Weight Gain With Childhood Body Size and Composition" (Pediatrics, 2023), "Metabolic and fecal microbial changes in adult fetal growth restricted mice" (Pediatric Research, 2024), "Calorie restriction during gestation impacts maternal and offspring fecal microbiome in mice" (Frontiers in Endocrinology, 2024), and "Breastfeeding for the Re-Hospitalized Infant" (Hospital Pediatrics, 2025).
