About Charles Sherr

Dr. Charles J. Sherr has made seminal contributions to the understanding of oncogenes and tumor suppressors, the mechanics of cell division cycle control, and how key cell cycle regulators are perturbed in cancer. His accomplishments have justly earned his election to the AAAS, to the National Academies of Science and Medicine, and as an Inaugural Fellow of AACR, among notable other awards and appointments. Dr. Sherr was the recipient of continuous, unfettered support from the Howard Hughes Medical Institute for 30 years until he transitioned to emeritus status in 2019. In partnership with longtime collaborator and spouse, Dr. Martine Roussel, Dr. Sherr transformed the basic and translational pediatric cancer research landscape of St. Jude.
