Aubrey de Grey is a biomedical gerontologist with a reputation for bold ideas. He has spent more than two decades proposing that the human body, like any machine, can be repaired and maintained far beyond what we currently consider possible. As President and Chief Science Officer of the Longevity Escape Velocity Foundation, he leads one of the most radical research agendas in modern science: to develop therapies that not only slow ageing but reverse it.
De Grey’s central idea is striking in its simplicity. Ageing, he argues, is not an enigma but a problem that can be addressed with engineering solutions. He says ageing is caused by seven categories of cellular and molecular damage that accumulate over time. And each category has a feasible repair strategy, from stem cell therapy to gene editing, that can restore the body to a more youthful state. His approach, known as Strategies for Engineered Negligible Senescence (SENS), has sparked debate across the scientific world and helped launch the field of rejuvenation biotechnology.
Once dismissed as fringe, Aubrey de Grey’s views have gained traction as advances in genetics, regenerative medicine and AI-driven diagnostics converge. He was among the first to predict that anti-ageing science would shift from theory to application. With each passing year, the evidence appears to edge closer to his side.
De Grey is the author of The Mitochondrial Free Radical Theory of Aging and co-author of Ending Aging, where he outlines how periodic repairs could allow the body to remain biologically young indefinitely. He believes that the first person to live to a thousand may already be alive.
Not everyone in the scientific community agrees with his timelines but few dispute the impact of his ideas. In a field long marked by fatalism, de Grey insists on possibility. For him, the ultimate goal is not immortality, but health. A future in which ageing-related diseases are no longer inevitable, and human vitality doesn’t end with chronology. If Aubrey de Grey is right, the biggest disruption of the 21st century may not be technological but biological.
