David A. Sinclair, Ph.D., A.O. is a Professor in the Department of Genetics at Harvard Medical School who works on understanding why we age and how to slow and reverse its effects. Prof. Sinclair is known for his Information Theory of Aging, which states that information loss over time is the key driver of aging, a process that can be reset using a back-up copy of youthful information in each cell. His lab was the first to identify a role for NAD biosynthesis in the regulation of lifespan, that sirtuins are involved in fasting’s benefits, and showed aging can be controlled in both directions. He has published over 200 scientific papers, is a co-inventor on over 50 patents, co-founded numerous successful companies and is the author of the New York Times Best Seller Lifespan: Why We Don’t Have To. He serves as co-chief editor of the scientific journal Aging and has received more than 35 honors including the Noble Genius Award from the World Forum, the NIH Director’s Pioneer award and TIME magazine’s “100 most influential people in the world” & “Top 50 people in Healthcare”. In 2018, he became an Officer of the Order of Australia (AO).
