David Sinclair, Ph.D., is a professor of genetics and co-director of the Paul F. Glenn Center for Biology of Aging Research at Harvard Medical School. He also leads the Sinclair Research Group at Harvard. A prominent and, at times, controversial figure in the field of aging research, Dr. Sinclair is known for advancing the view that aging is a biological process that may be slowed, or even reversed.
His laboratory’s work focuses on understanding why we age and exploring ways to extend healthspan and, ultimately, lifespan. He has been named one of Time Magazine’s 100 Most Influential People and is the author of the New York Times bestselling book Lifespan: Why We Age—and Why We Don’t Have To.
In his recording, Dr. Sinclair offers students an opportunity to explore the human body through the lens of aging. He explains the cellular and molecular processes that contribute to aging, including his hypothesis that aging may result from a “loss of information.” Students are introduced to the interconnectedness of the body’s systems, the role of intercellular communication, and current thinking about how lifestyle and environment influence longevity. As he notes, “Our lifespan is only 20% genetic.”
Dr. Sinclair also shares findings from his research at Harvard and reflects on the role of curiosity and persistence in scientific discovery, emphasizing how questions, rather than answers, often drive meaningful advances.
