Learn More About Natalie D. Shaw, M.D., MMSc.

Natalie D. Shaw, M.D., M.M.Sc. received a B.S. from Cornell University, an M.D. from the State University of New York (SUNY) at Buffalo, and a Masters in Medical Sciences (MMSc) from Harvard Medical School. She completed her pediatrics residency at Children's Hospital of Pittsburgh, a pediatric endocrinology fellowship at Boston Children's Hospital, and a clinical research fellowship in the Reproductive Endocrine Unit at Massachusetts General Hospital.

In 2015, Shaw was one of five junior researchers selected as a Lasker Clinical Research Scholar by the National Institutes of Health. The Lasker program is a joint partnership between the NIH and the Lasker Foundation designed to support a small number of exceptional clinical researchers in the early stages of their careers. Its goal is to promote the development of physician-scientists as they transition to fully independent positions. When Shaw joined NIEHS in September 2015, she became the first Lasker Scholar in the history of the institute.
