About Me

I have 40 years of experience caring for children and adolescents with endocrine disorders and diabetes. I served for 31 years as Chief of Duke’s Division of Pediatric Endocrinology and Diabetes. I have played a leading role in the field of clinical pediatric nutrition and diabetes. My colleagues and I were the first to demonstrate the benefits of pharmacotherapy in children and adolescents with pre-diabetes, and we pioneered studies in the pathogenesis and treatment of severe acute malnutrition in the developing world. My colleagues and I were the first to use insulin pumps in infants and toddlers with type 1 diabetes, and we spearheaded the screening of diabetic children for celiac disease. I won Duke’s Golden Apple Award for outstanding teaching and was awarded (continuously since 2001) membership in America’s Top Doctors, sponsored by US News & World Report/Castle Connolly, which includes only 37 pediatric endocrinologists/diabetologists nationwide. I am also included in Best Doctors in America.

Clinical Focus and Research

My Research Interests

My laboratory research explored roles of maternal and placental hormones in the regulation of fetal growth. More recently, I have played a leading role in clinical pediatric nutrition and diabetes. My colleagues and I were the first to demonstrate the benefits of pharmacotherapy in children and adolescents with pre-diabetes, and we pioneered studies in the pathogenesis and treatment of severe acute malnutrition in the developing world. My colleagues and I were the first to use insulin pumps in infants and toddlers with type 1 diabetes, and we spearheaded the screening of diabetic children for celiac disease.
