Research Topics

We investigate the cellular and molecular mechanisms governing childhood growth and development. We particularly focus on growth at the growth plate, which drives bone elongation and therefore determines height. One goal of this work is to gain insight into the many human genetic disorders that cause childhood growth failure and overgrowth. A second goal is to develop new treatments for children with severe growth disorders.


Dr. 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. In addition to his research role, Dr. Baron serves as an attending physician for the pediatric endocrinology clinic and consultative service and teaches clinical fellows in the NICHD pediatric endocrinology training program.
