Dr. Sheila Gahagan is Chief of Academic General Pediatrics, and holds the Stein Chair in Developmental and Behavioral Pediatrics at the University of California, San Diego. She has expertise in developmental origins of health and disease, focusing much of her work on early life nutrition and long-term health consequences. One line of research focuses on the role of iron on infant neurodevelopment and its long-term effects. In addition, she is an expert on children’s growth, development of obesity and its consequences. She expects her research to inform early life prevention of childhood and adult disease. Throughout her career, Dr. Gahagan has sought out interdisciplinary collaborations seeing the importance of approaching complex questions from multiple paradigms. Since 2001, Gahagan has participated in research with the Santiago Longitudinal Study, a Chilean cohort originally evaluated as part of an iron deficiency anemia preventive trial. Since 2001, she has had NIH funding including as the Principal Investigator of a multi-institution, interdisciplinary, international project to study “Biopsychosocial Determinants of Obesity/ Cardiovascular Risk”. She has also served as PI in multiple PI leadership plans on three other projects involving the same cohort. Dr. Gahagan is sought out as a coinvestigator for her expertise related to obesity, developmental processes, and health disparities.
