Aubrey de Grey

Aubrey de Grey is a scientist.

He studies how we get old. He thinks we can fix the damage in our bodies. This damage is what makes us age. He wants to use new tools to help people stay healthy. He even thinks some people could live a very long time. He also studies math. He likes to solve hard puzzles with shapes. He works to find new ways to help us live well.

Aubrey de Grey is a scientist who studies aging.

He is a gerontologist. This is a scientist who studies how living things grow old. He thinks we can use new tools to fix the body. He says aging is like a set of side effects from how our bodies work.

He helped start the SENS Research Foundation. This group works to find ways to treat diseases of aging. He also came up with an idea called xenocatabolism. This is a way to use tiny microbes to break down bad things in the body. He thinks we could use certain genes to help our bodies clean themselves.

De Grey also studies math. He worked on a hard math puzzle about shapes. This problem is called the Hadwiger–Nelson problem. He made the first progress on it in over 60 years. In 2021, he left his job at the SENS Foundation. An investigation found he had made offensive remarks to two women.

Aubrey de Grey is a scientist who studies how living things age. He is a biomedical gerontologist, which means he studies the biology of growing old.

De Grey believes that medical technology might one day stop people from dying due to age. He views aging as a collection of side effects from how our bodies work. These side effects eventually cause the body to break down. He thinks we can use science to fix these issues. His goal is to help people stay healthy for much longer.

One way he thinks we can help is through a plan called SENS. SENS stands for strategies for engineered negligible senescence. This is a way to prevent the body and mind from declining. He also came up with an idea called xenocatabolism. This is a way to use tiny microbes to clean the body. He suggests we could use genes from microbes to break down bad things. These microbes could help get rid of waste that our bodies cannot clean on their own.

De Grey has had a very busy career in many different fields. He was born in London, England, on April 20, 1963. He studied computer science at Trinity Hall, Cambridge, and graduated in 1985. At first, he worked with artificial intelligence and software. Later, he taught himself biology by reading many books and attending meetings. In 2000, Cambridge gave him a Ph.D. based on his work about mitochondria. Mitochondria are tiny parts inside cells that can get damaged over time.

He has worked on many big projects and written important books. In 1999, he wrote a book about how damage to mitochondria affects life. In 2007, he co-authored a book called Ending Aging. He also helped start the SENS Research Foundation in California in 2009. This group works on regenerative medicine to treat diseases of aging. He served as their Chief Science Officer for many years. In 2021, he left this role after an investigation into his conduct. The investigation found he had made offensive remarks to two women.

De Grey is also a very talented mathematician. He worked on a famous math puzzle called the Hadwiger–Nelson problem. This problem is about coloring shapes on a flat surface. He made the first progress on this puzzle in over 60 years. His work used a graph with 1,581 points, called vertices. Other researchers later found a way to do it with only 510 points. This shows how math and science can work together to solve hard problems.

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.
