Frank Slack received his B.Sc from the University of Cape Town in South Africa, before completing his Ph.D in molecular biology at Tufts University School of Medicine. He started work on microRNAs as a postdoctoral fellow in Gary Ruvkun’s laboratory at Harvard Medical School, where he co-discovered the second known microRNA, let-7. He is currently a Professor in the Department of Molecular, Cellular and Developmental Biology at Yale University. The Slack laboratory studies the roles of microRNAs and their targets in cancer, development, and aging.
