Aubrey de Grey is a British biomedical gerontologist specializing in the science of aging. A gerontologist is a scientist who studies the biological processes of growing old. De Grey is best known for his theory that aging is not an inevitable fate. Instead, he views aging as a collection of accumulated side effects from metabolism. He believes that medical technology may eventually allow people to avoid death from age-related causes.

De Grey's primary framework for addressing aging is a plan called SENS. SENS stands for strategies for engineered negligible senescence. The goal of SENS is to prevent physical and cognitive decline through regenerative medicine. He argues that most of the fundamental knowledge needed to develop these therapies already exists. He believes the main hurdle is that science is currently ahead of its funding. His work focuses on identifying specific technological ways to reverse the damage caused by aging.

One specific concept de Grey proposed is known as xenocatabolism. This is a method of medical bioremediation that uses microbial enzymes to clean the body. He suggests that certain microbes can break down substances like amyloid and cholesterol. These microbes are often found in environments like graveyards where they feed on organic matter. De Grey proposes that we could identify the genes responsible for this ability. By introducing these genes into humans, we might enhance our ability to break down waste that our bodies cannot naturally clear.

De Grey's academic journey began in computer science at Trinity Hall, Cambridge. He graduated in 1985 and initially worked as an artificial intelligence researcher. He later transitioned into biology after realizing that many biologists were not focused on solving aging. He taught himself much of biology by reading journals and attending conferences. In 2000, Cambridge awarded him a Ph.D. by publication. This degree was based on his 1999 book, *The Mitochondrial Free Radical Theory of Aging*. In this work, he explored how damage to mitochondrial DNA might extend a lifespan.

His career includes significant leadership roles in the longevity community. He co-founded the Methuselah Foundation and later the SENS Research Foundation in 2009. He served as the Chief Science Officer of the SENS Research Foundation until 2021. His departure followed an investigation into allegations of sexual harassment. An independent probe concluded that he had made offensive remarks to two women. Despite these controversies, his research ideas continue to be discussed in the scientific community.

De Grey has also made notable contributions to the field of mathematics. He worked on the Hadwiger–Nelson problem, which involves geometric graph theory. This problem asks how many colors are needed to color a plane so that no two points at a unit distance have the same color. In 2018, de Grey made the first progress on this problem in over 60 years. He constructed a unit-distance graph using 1,581 vertices, or points. While later researchers reduced this number to 510, his work was a major breakthrough in the field.

His theories have sparked intense debate among scientists. In 2005, *MIT Technology Review* held a challenge to see if anyone could prove the SENS approach was unworthy of debate. While no one completely disproved SENS, judges noted that its proposals could not yet be verified with current technology. Some scientists have criticized his ideas for being too simple or lacking ethical considerations. However, de Grey remains optimistic about the future of longevity. He coined the term "Methuselarity" to describe the point where medical improvements allow people to live indefinitely through successive generations of technology.
