Barbara Migeon, MD, has held fellowships in pediatrics, endocrinology and genetics. She is board certified in pediatrics, biochemical genetics and cytogenetics. She was the founding director of the Hopkins PhD Program in Human Genetics. Her research has been focused on the molecular mechanisms of X inactivation in human cell and the clinical consequences of the single active X chromosome.
