Jim White is Assistant Professor in Medicine, Division of Hematology and Senior Fellow in the Duke Center for Aging and Human Development. He earned a PhD in Exercise Science, specializing in skeletal muscle biology, at the University of South Carolina, Columbia, followed by a postdoctoral fellowship in the lab of Bruce Spiegelman at Harvard Medical School. There he worked in the areas of muscle metabolism and metabolic disease. His laboratory studies mechanisms of age-related functional decline of stem cells within skeletal muscle, vasculature and the immune system. His research program employs a wide range of investigation including in vitro cellular assays, mouse models and human studies. The overarching goal of this work is to elucidate mechanisms of stem cell function in their respective tissues and rescue/prevent age-related dysfunction.
