De Grey argues that the fundamental knowledge needed to develop effective anti-aging medicine mostly already exists, and that the science is ahead of the funding.

A major activity of the Methuselah Foundation is the ],<ref></ref> a prize designed to hasten the research into effective life extension interventions by awarding monetary prizes to researchers who stretch the lifespan of mice to unprecedented lengths. Regarding this, de Grey stated in March 2005 "if we are to bring about real regenerative therapies that will benefit not just future generations, but those of us who are alive today, we must encourage scientists to work on the problem of aging." The prize reached 4.2 ] million in February 2007. De Grey believes that once dramatic life extension of already middle-aged mice has been achieved, a large amount of funding will be diverted to this kind of research, which would accelerate progress in doing the same for humans.

#]-causing nuclear mutations/epimutations:
#:These are changes to the nuclear ] (nDNA), the molecule that contains our genetic information, or to proteins which bind to the nDNA. Certain ]s can lead to cancer, and, according to de Grey, non-cancerous mutations and ]s do not contribute to aging within a normal lifespan, so cancer is the only endpoint of these types of damage that must be addressed.
#]l mutations:
#:Mitochondria are components in our ] that are important for ] production. They contain their own genetic material, and mutations to their DNA can affect a cell’s ability to function properly. Indirectly, these mutations may accelerate many aspects of aging.
#Intracellular aggregates:
#:Our cells are constantly breaking down ]s and other molecules that are no longer useful or which can be harmful. Those molecules which can’t be digested simply accumulate as junk inside our cells. ], ] and all kinds of ]s (such as Alzheimer's disease) are associated with this problem.
#Extracellular aggregates:
#:Harmful junk protein can also accumulate outside of our cells. The amyloid plaque seen in the brains of ] patients is one example.
#Cell loss:
#:Some of the cells in our bodies cannot be replaced, or can only be replaced very slowly - more slowly than they die. This decrease in cell number causes the heart to become weaker with age, and it also causes ] and impairs the ].
#]:
#:This is a phenomenon where the cells are no longer able to ], but also do not die and let others divide. They may also do other things that they’re not supposed to, like secreting proteins that could be harmful. Immune senescence and ] are caused by this.{{Fact|date=April 2008}}

Aubrey David Nicholas Jasper de Grey (/dəˈɡreɪ/; born 20 April 1963) is an English biomedical gerontologist. He is the author of The Mitochondrial Free Radical Theory of Aging (1999) and co-author of Ending Aging (2007). De Grey is known for his view that medical technology may enable human beings alive today not to die from age-related causes. As an amateur mathematician, he has contributed to the study of the Hadwiger–Nelson problem in geometric graph theory, making the first progress on the problem in over 60 years.

De Grey is an international adjunct professor of the Moscow Institute of Physics and Technology. In August 2021, he was removed as the Chief Science Officer of the SENS Research Foundation after he had allegedly attempted to interfere in a probe investigating sexual harassment allegations against him. In September 2021, an independent investigation concluded that he had made offensive remarks to two women.

Early life and education

De Grey was born on 20 April 1963 and brought up in London, England. He told The Observer that he never knew his father, and that his mother Cordelia, an artist, encouraged him in the areas in which she herself was weakest: science and mathematics. De Grey was educated at Sussex House School and Harrow School. He attended university at Trinity Hall, Cambridge, graduating with a BA in computer science in 1985.

Career

After graduation in 1985, de Grey joined Sinclair Research as an artificial intelligence (AI) researcher and software engineer. In 1986, along with SRL colleague Aaron Turner, he co-founded Man-Made Minions Ltd. in order to pursue the development of an automated formal program verifier. At a graduate party in Cambridge, de Grey met fruit fly geneticist Adelaide Carpenter, whom he would marry in 1991. Through her, he was introduced to the intersection of biology and programming when her boss needed someone who knew about computers and biology to take over the running of a database on fruit flies. In the early 1990s, he switched fields from AI research to biomedical gerontology, after realising that "biologists by and large were not terribly interested in doing anything about aging". He educated himself in biology by reading journals and textbooks, attending conferences, and being tutored by Professor Carpenter. From 1992 to 2006, he was in charge of software development at the university's Genetics Department for the FlyBase genetic database.

Cambridge awarded de Grey a Ph.D. by publication in biology on 9 December 2000. The degree was based on his 1999 book The Mitochondrial Free Radical Theory of Aging, in which de Grey wrote that obviating damage to mitochondrial DNA might by itself extend lifespan significantly, though he said it was more likely that cumulative damage to mitochondria is a significant cause of senescence, but not the single dominant cause.

Strategies

In 2005, de Grey argued that most of the fundamental knowledge needed to develop effective anti-aging medicine already exists, and that the science is ahead of the funding. He described his work as identifying and promoting specific technological approaches to the reversal of various aspects of aging, or, as he puts it, "... the set of accumulated side effects from metabolism that eventually kills us."

Aubrey de Grey explaining the SENS approach in a talk in 2010

As of 2005, de Grey's work centered on a detailed plan called strategies for engineered negligible senescence (SENS), which is aimed at preventing age-related physical and cognitive decline. In March 2009, he co-founded the SENS Research Foundation (named SENS Foundation until early 2013), a non-profit organisation based in California, United States, where he served until 2021 as Chief Science Officer. The foundation "works to develop, promote and ensure widespread access to regenerative medicine solutions to the disabilities and diseases of aging", focusing on the strategies for engineered negligible senescence. Before March 2009, the SENS research program was mainly pursued by the Methuselah Foundation, co-founded by de Grey.

A major activity of the Methuselah Foundation is the Methuselah Mouse Prize, a prize designed to incentivize research into effective life extension interventions by awarding monetary prizes to researchers who stretch the lifespan of mice to unprecedented lengths. De Grey stated in March 2005 "if we are to bring about real regenerative therapies that will benefit not just future generations, but those of us who are alive today, we must encourage scientists to work on the problem of aging." The prize reached US$4.2 million in February 2007.

In 2007, de Grey wrote the book Ending Aging with the assistance of Michael Rae.

In a 2008 broadcast on Franco-German TV network Arte, de Grey claimed that the first human to live 1,000 years was probably already alive, and might even be between 50 and 60 years old already.

In 2012, de Grey inherited more than US$16 million, US$13 million of which he donated to the SENS Research Foundation.

In 2022, de Grey started the Longevity Escape Velocity Foundation, which funded and launched a project focusing on robust mouse rejuvenation.

Mathematics

On 8 April 2018, de Grey posted a paper to arXiv explicitly constructing a unit-distance graph in the plane that cannot be colored with fewer than five colors, increasing the previously known lower bound by one and making the first progress on the problem in over 60 years. The previous lower bound of four was due to the problem's original proposal in 1950 by Hugo Hadwiger and Edward Nelson. De Grey's graph has 1581 vertices, but it has since been reduced to 510 by independent researchers.

AgeX Therapeutics

De Grey was formerly Vice President of New Technology Discovery at AgeX Therapeutics, a startup in the longevity space helmed by Michael D. West. He was appointed to the position within the company in July 2017.

Xenocatabolism

Xenocatabolism is a concept in medical bioremediation that relies upon introducing into the body microbial enzymes that break down pathogenic lysosomal, cytosolic and extracellular aggregates. The term, also called xenohydrolysis, was coined by de Grey, building upon the work of others. De Grey posited that there are microbes that feed on substances such as amyloid, cholesterol and other related substances in places that are full of human remains, such as graveyards. This was based on the microbial infallibility hypothesis. He states that "the biomedical approach would be to identify the genetic basis for that capacity, and to put one or two genes into ourselves, thereby enhancing our own ability to break things down, and to thereby get rid of things that we cannot naturally break down". In order to add credibility to the concept, de Grey created an experiment using soil from a graveyard and took the bacteria from it. He used lipofuscin, "one of the major things that accumulates indigestibly in the body" – which some of the bacteria broke down, lending credibility to the hypothesis. De Grey presented this theory on May 29, 2007, at the Googleplex Google TechTalks.

Views

Future of anti-aging medicine

De Grey believes that medical technology may enable human beings alive today not to die from age-related causes.

He coined the term Methuselarity, which he defines as the moment when medical therapies will rejuvenate people enough to continue living healthily until the next improved generation of rejuvenation biotechnology, and so on, indefinitely. According to de Grey, that is synonymous with the point where science achieves longevity escape velocity–the minimum rate at which those therapies need to be improved in order to allow people not to suffer from age-related ill-health at any age. In 2022, he stated that there is a 50% chance that this breakthrough was only 15 years away.

However, de Grey views the fatalistic attitude toward aging in society, as he sees it, as a hurdle in the rapid development of anti-aging medicine, which he calls "pro-aging trance".

Technology Review debate

In 2005, MIT Technology Review, in cooperation with the Methuselah Foundation, announced a US$20,000 prize for any molecular biologist who could demonstrate that SENS was "so wrong that it is unworthy of learned debate." The judges of the challenge were Rodney Brooks, Anita Goel, Vikram Sheel Kumar, Nathan Myhrvold, and Craig Venter. Five submissions were made, of which three met the terms of the challenge. De Grey wrote a rebuttal to each submission, and the challengers wrote responses to each rebuttal. The judges concluded that none of the challengers had disproved SENS, but the magazine opined that Preston Estep's submission was particularly eloquent and well written, and awarded the contestant US$10,000. The judges also noted "the proponents of SENS have not made a compelling case for SENS", and wrote that many of its proposals could not be verified with the current level of scientific knowledge and technology, concluding that "SENS does not compel the assent of many knowledgeable scientists; but neither is it demonstrably wrong." The critics single out three proposed therapies for criticism: somatic telomerase deletion, somatic mitochondrial genome engineering, and the use of transgenic microbial hydrolase.

Later in 2005, he was the subject of an associated critical editorial article in the MIT Technology Review, which viewed his theories as oversimplifying anti-aging as a scientific goal, and expressed concern at a lack of ethical and moral considerations towards anti-aging research.

EMBO Reports

A 2005 article about SENS published in the viewpoint section of EMBO Reports by 28 scientists concluded that none of de Grey's hypotheses "have ever been shown to extend the lifespan of any organism, let alone humans". The SENS Research Foundation, of which de Grey was a co-founder, acknowledged this, stating, "If you want to reverse the damage of aging right now I'm afraid the simple answer is, you can't." Moreover, de Grey argued that this reveals a serious gap in understanding between basic scientists and technologists and between biologists studying aging and those studying regenerative medicine.

The 31-member Research Advisory Board of de Grey's SENS Research Foundation have signed an endorsement of the plausibility of the SENS approach. In 2021, the National Institute on Aging (NIA), a division of the U.S. National Institutes of Health (NIH), showcased a SENS research project and provided a grant for the research.

Future of work

According to de Grey, automation will take over most jobs in the future. He also believes that the introduction of a universal basic income will be necessary to find "some new way to distribute wealth that doesn’t depend on being paid to do things we wouldn’t otherwise do".

Cryonics

De Grey is a cryonicist, having signed up with Alcor. When asked in an interview about his views on cryonics, he answered that " it's an absolute tragedy that cryonics is still such a backwater publicly and that a large majority of people still believe that it has no chance of ever working", arguing "If people understood it better, there would be more research done to develop better cryopreservation technologies, and more people would have a chance at life."

Sexual harassment allegations and aftermath

In August 2021, following allegations of sexual harassment by two women, de Grey was put on administrative leave by the SENS Research Foundation (SRF).

Both women describe situations in which he, {...} explicitly spoke with them about sex. According to Halioua’s account, he told her that it was her responsibility to sleep with SENS donors to encourage financial contributions. Deming was 17 when, she alleges, de Grey told her he wanted to speak with her about his “adventurous love life.” Deming says that when she recently became aware that this was not a one-off incident, she was “angry to realize that Aubrey inappropriately propositioned more than one woman, many in the community knew about it, and no one did anything,” she writes.

The SRF board of directors decided to remove de Grey from his position as chief science officer, severing all ties with him following the report that he had allegedly attempted to interfere with the investigation.

The independent investigator determined that de Grey made inappropriate remarks to Deming and Halioua. The investigator also decided de Grey's attempt to communicate with Halioua via a third party constituted interference, although de Grey stated he believed that phase of the investigation had concluded. The investigator found that various other allegations against de Grey were not substantiated.

In March 2022, SRF released a statement regarding de Grey's employment affirming that while his actions "did substantiate instances of poor judgment and boundary-crossing behaviors, Dr. de Grey is not a sexual predator."

De Grey's removal from SRF led three major donors to sue SRF for fraud, where they alleged that at the time they had donated (July 2021) the SRF board was already engineering de Grey’s removal but had concealed this from the wider world. The donors said that had they known that de Grey would not be substantially responsible for disbursing donated funds they would not have donated. The suit was settled within three months and did not proceed to a discovery phase. The nature of the settlement was not made public, but de Grey has stated that the LEV Foundation, his new organization, was formed "as a result". Another lawsuit making similar accusations was filed by donor April Okita on November 21st, 2024.
