Clinical Interests

Dr. Duncan earned her B.S. at Vanderbilty University and her M.D. at University of Chicago. She remained at The University of Chicago for pediatric residency and a year as Chief Resident before going to Johns Hopkins for fellowship training in Pediatric Critical Care. At Hopkins she developed her interest in basic science research. She came to Washington University in 2004 and developed a research program focused in cardiac mitochondrial metabolism in obesity and diabetes. She later transitioned her work to focus on the impact of maternal obesity and diabetes on offspring, with a specific focus on mitochondrial metabolism in the offspring. Her lab established a Drosophila model to study the impact of maternal obesity on the offpsring, and more recently has been focused on clinical/translational projects in an effort to focus on mitochondrial function in human neonates.
