Jeffrey Baron is a senior investigator and head of the Section on Growth and Development in NICHD. He received his M.D. degree from the University of Texas Southwestern Medical School. He completed a residency in pediatrics at Yale-New Haven Hospital and a fellowship in pediatric endocrinology in the Developmental Endocrinology Branch of NICHD.
The Section on Growth and Development, headed by Dr. Baron, investigates the cellular and molecular mechanisms governing childhood growth and development. Recently this research group has focused on the mechanisms that allow rapid proliferation and hence rapid body growth in young mammals and subsequently suppress proliferation, thus setting a fundamental limit on the adult body size of the species. One goal of this work is to gain insight into the many human genetic disorders that cause childhood growth failure and overgrowth. In addition, further investigation of the identified growth-limiting mechanisms may lead to broader medical applications, because disruption of these mechanisms may contribute to oncogenesis, and conversely transient therapeutic suspension of growth-limiting mechanisms in adult cells might be used to achieve tissue regeneration.
In addition to his research role, Dr. Baron also serves as an attending physician for the pediatric endocrinology clinic and consultative service and teaches clinical fellows in the NICHD pediatric endocrinology training program.
