Aubrey de Grey is a British biomedical gerontologist known for his research on aging and longevity. He is the co-founder and Chief Science Officer of the SENS Research Foundation, an organization focused on developing therapies to combat age-related diseases. De Grey advocates for the idea that aging can be treated as a medical condition. He is recognized for his concept of "strategies for engineered negligible senescence" (SENS), which outlines potential methods to repair cellular damage that accumulates over time. De Grey's work has sparked discussions in the fields of gerontology and biogerontology, influencing both scientific research and public perception of aging.
