David Sinclair is a professor in the Department of Genetics and co-director of the Paul F. Glenn Center for the Biology of Aging at Harvard Medical School, where he and his colleagues study sirtuins—protein-modifying enzymes that respond to changing NAD+ levels and to caloric restriction—as well as chromatin, energy metabolism, mitochondria, learning and memory, neurodegeneration, cancer, and cellular reprogramming.

David has suggested that aging is a disease—and that we may soon have the tools to put it into remission—and he has called for greater international attention to the social, economic and political risks and benefits of a world in which billions of people can live much longer and much healthier lives.

He is the co-founder of several biotechnology companies and is on the boards of several others. His first book Lifespan became a New York Times best seller in 2019.

He is also co-founder and co-chief editor of the journal Aging. He is an inventor on 35 patents and has received more than 35 awards and honors. In 2014, he was on Time Magazine’s list of the “100 Most Influential People in the World,” and listed as Time’s Top 50 in healthcare in 2018.
