Barbara J. Meyer

Barbara J. Meyer is a biologist and geneticist, noted for her pioneering research on lambda phage, a virus that infects bacteria; discovery of the master control gene involved in sex determination; and studies of gene regulation, particularly dosage compensation. Meyer's work has revealed mechanisms of sex determination and dosage compensation—that balance X-chromosome gene expression between the sexes in Caenorhabditis elegans that continue to serve as the foundation of diverse areas of study on chromosome structure and function today.
