Cynthia Kenyon is revolutionizing our understanding of aging. As an expert in biochemistry and biophysics at the University of California at San Francisco, she is particularly interested in the influence that genetics have on age-related diseases (from cancer to heart failure) in living things.

Her biggest breakthrough was figuring out that there’s a “universal hormonal control for aging”: carbohydrate intake, which can have a dramatic effect on how two critical genes behave, reducing insulin production and boosting repair and renovation activities. So far, her theory has proved true for worms, mice, rats, and monkeys — and she suspects it applies to humans, too.

By studying aging, Kenyon believes that she and other scientists (many of whom have successfully duplicated her experiments) will be able to pinpoint the molecules responsible for the onset of age-related diseases in people and prevent them. She’s co-founded a drug-development company called Elixir Pharmaceuticals to do just that.

She says: "The link between aging and age-related disease suggests an entirely new way to combat many diseases all at once; namely, by going after their greatest risk factor: aging itself."

Kenyon graduated valedictorian in chemistry from the University of Georgia in 1976. She received her Ph.D. from MIT in 1981 and was a postdoctoral fellow with Nobel laureate Sydney Brenner in Cambridge, England. In 1986 she joined the faculty of the University of California, San Francisco, where she became the Herb Boyer Distinguished Professor and an American Cancer Society Professor, before joining Calico in 2014. Kenyon is a member of the U.S. National Academy of Sciences, the National Academy of Medicine and the American Academy of Arts and Sciences, and she is a former president of the Genetics Society of America. She has received many scientific honors and awards.
