Dr. Julie Hoover-Fong is an associate professor of pediatrics and clinical geneticist in the McKusick-Nathans Institute of Genetic Medicine. She also serves as director of the Greenberg Center for Skeletal Dysplasias. 

Dr. Hoover-Fong holds a bachelor’s degree in human nutrition from The Ohio State University, where she also completed her medical degree. She received her PhD in the Graduate Training Program in Clinical Investigation at the Johns Hopkins University School of Medicine and Bloomberg School of Public Health.
