Karen Winer, M.D., is the director of the pediatric endocrinology and bone programs, which focus on bone health, disorders of growth and puberty, metabolic syndrome, malnutrition, obesity, and diabetes. Other areas of interest include studies related to the determinants of peak bone mass and fat-muscle-bone interactions during infancy and childhood and programs designed to identify and support young physician scientists embarking on careers in academic medicine. Dr. Winer is also the program director for the Pediatric Scientist Development Program, a national career development and training program that funds pediatrician scientists during subspecialty fellowship years.    

Dr. Winer, a board-certified pediatric endocrinologist, completed her pediatric residency training at the Mount Sinai Medical Center in New York, and her subspecialty training in pediatric endocrinology at the NIH. She was the first to study parathyroid hormone (PTH) replacement therapy in the treatment of hypoparathyroidism. She established the safety and efficacy of PTH delivered by single and multiple daily injections. She further optimized PTH replacement therapy through a continuous pump in both adults and children. Dr. Winer joined the Pediatric Growth and Nutrition Branch to direct and develop programs in pediatric endocrinology, bone health, and osteoporosis prevention. In 2001, she established Diabetes Research in Children Network (DirecNet), a network that has contributed to the development of the artificial pancreas and recently was the first to characterize structural and functional brain changes in young diabetic children exposed to chronic intermittent dysglycemia. Additionally, she established another highly acclaimed pediatric research network, the Bone Mineral Density in Childhood Study (BMDCS), which developed longitudinal reference standards for bone density, linear height velocity, and bone accretion velocity.  She has received NIH Director’s and the NICHD Merit awards for her work. She is also a member of the editorial board of the Journal of Clinical Endocrinology and Metabolism.
