Research Interests & Projects

I am interested in how maternal diet and timing of eating and sleeping during pregnancy (chronobiology) impacts maternal metabolic health and offspring through adulthood. My dissertation is multidisciplinary, utilizing both preclinical and human observational methods. My preclinical work involves time-restricted feeding during gestation on maternal glycemia and offspring metabolic health. The observational PRESS study (Pregnancy Related Eating, Sleeping and Stress) is a longitudinal cohort that assesses associations between the timing of eating and sleeping during pregnancy and maternal and child health outcomes.
