Dr. Barbara Migeon is a professor of pediatrics at the Johns Hopkins University School of Medicine. Her research focuses on sex determination, relevance to human disease, genomic imprinting in human cells, and molecular basis of X chromosome inactivation.
Dr. Migeon is currently engaged in research related to the mechanisms responsible for X chromosome dosage compensation in human females. Her research concerns not only the molecular basis for the single active X, but also the genetic consequences (cellular mosaicism, cell selection). She is also studying the effect of mosaicism on the phenotype and health of women.
She received her undergraduate degree from Smith College and earned her M.D. from the University of Buffalo. After completing a residency in pediatrics from Johns Hopkins, she performed a fellowship in endocrinology at Harvard and a fellowship in genetics at Johns Hopkins.
Dr. Migeon has had an active career, participating in numerous scientific committees related to human genetics and women in science. She has been on the editorial board of various scientific publications and served as the associate editor of Cancer Research and The Journal of Experimental Zoology. She has published extensively about her research and mentored scores of medical students and researchers.
