David Sinclair Net Worth

David Sinclair is a professor of genetics at Harvard Medical School, co-director of the Paul F. Glenn Center for Biology of Aging Research, and one of the world's leading scientists in the field of aging and longevity. His book Lifespan: Why We Age — and Why We Don't Have To became a New York Times bestseller and presented the revolutionary thesis that aging itself is a disease — and one that can be treated.

Born and raised in Sydney, Australia, Sinclair earned his PhD from the University of New South Wales before moving to MIT as a postdoctoral researcher in the laboratory of Leonard Guarente, where he co-discovered the role of sirtuins — a family of proteins that play a critical role in aging and cellular health. This work launched his career as one of the most cited and influential aging researchers in the world.

At Harvard, Sinclair's laboratory has published groundbreaking research on NAD+ (nicotinamide adenine dinucleotide) precursors, resveratrol, and epigenetic reprogramming. His work on the Information Theory of Aging — the idea that aging is caused by the loss of epigenetic information, not just genetic mutations — has fundamentally shifted how scientists think about why we age and what can be done about it.

Sinclair was named to Time magazine's list of the 100 Most Influential People in the World and has been recognized with numerous awards including the NIH Director's Pioneer Award. He has co-founded multiple biotechnology companies, including Sirtris Pharmaceuticals (acquired by GlaxoSmithKline for $720 million) and Life Biosciences, to translate his research into therapies that could extend healthy human lifespan.
