George Church (geneticist)
George McDonald Church is an American geneticist, molecular engineer, chemist, serial entrepreneur, and pioneer in personal genomics and synthetic biology. He is the Robert Winthrop Professor of Genetics at Harvard Medical School, Professor of Health Sciences and Technology at Harvard University and Massachusetts Institute of Technology, and a founding member of the Wyss Institute for Biologically Inspired Engineering at Harvard University.
Through his Harvard laboratory, Church has co-founded around 50 biotechnology companies. In 2018, the Church laboratory at Harvard spun off 16 biotechnology companies in one year. The Church laboratory works on research projects that are distributed in diverse areas of modern biology like developmental biology, neurobiology, information processing, medical genetics, aging, genomics, gene therapy, diagnostics, chemistry & bioengineering, space biology & space genetics, and ecosystem. Research and technology developments at the Church laboratory have impacted or made direct contributions to nearly all "next-generation sequencing " methods and companies.
In 2017, Time magazine listed him in Time 100, the list of 100 most influential people in the world. In 2022, he was featured among the most influential people in biopharma by Fierce Pharma., Church serves as a member of the Bulletin of the Atomic Scientists' Board of Sponsors.
Early life and education
Church was born on August 28, 1954, on MacDill Air Force Base in Tampa, Florida, and grew up in nearby Clearwater, Florida. He attended high school at the preparatory boarding school Phillips Academy, in Andover, Massachusetts, from 1968 to 1972. He then attended Duke University, where he obtained a B.S. degree in zoology and chemistry in two years.In the fall of 1973, Church began research work at Duke University with assistant professor of biochemistry Sung-Hou Kim, work that continued a year later in a graduate biochemistry program at Duke on an National Science Foundation fellowship.
As Peter Miller reported on Church for the National Geographic series, "The Innovators":
As a result, Church was not compliant with Duke graduate academic policies, and was withdrawn from the degree program in January 1976. He was told that " hope that whatever problems ... contributed to your lack of success ... at Duke will not keep you from a successful pursuit of a productive career." The work gave rise to publications including a PNAS report with Church as lead author on an early model for molecular interactions between the minor groove of double-stranded DNA and β-ribbons of proteins.
Church returned to graduate work at Harvard University in 1977 under Walter Gilbert, and completed a Ph.D in biochemistry and molecular biology working on mobile genetic elements within introns of yeast mitochondrial and mouse immunoglobulin genes.
Career
After completing his doctoral work, Church spent six months of 1984 at Biogen, the industrial laboratory site where Gilbert had relocated a sizable part of his former Harvard group. This was followed soon after by a Life Sciences Research Foundation postdoctoral fellowship at the University of California, San Francisco with Gail R. Martin, a member of the National Academy of Sciences and joint-discoverer of a technique to extract mouse embryonic stem cells.Church joined the Harvard Medical School faculty as an assistant professor in 1986. Church is now the Robert Winthrop Professor of Genetics at Harvard Medical School, and a member of the Harvard-MIT health sciences and technology faculty. He was also a founding member of the Wyss Institute for Biologically Inspired Engineering at Harvard University. He served as the director of the Center of Excellence in Genomic Science at the Harvard Medical School, funded by a P50-type award from the National Human Genome Research Institute, a part of the National Institutes of Health.
He co-founded Veritas Genetics and its European and Latin American subsidiary, Veritas Intercontinental, with the idea of bringing the benefits of genomic data to millions of people globally.
Church was elected a member of the National Academy of Engineering in 2012 for contributions to human genome sequencing technologies and DNA synthesis and assembly.
In 2018, Church co-founded Nebula Genomics, a personal genomics company that offers a whole-genome sequencing service. The company says that it is developing its own blockchain, intending to provide free sequencing in exchange for users' genomic and personal data. The decentralized nature of a blockchain also has the potential to improve aspects of data privacy and security, but identification of individuals could still be possible and law enforcement could still issue search warrants or subpoena the data.
In 2021, Church joined as a co-founder of HLTH.network, a healthcare blockchain startup which created the world's first global genomics data sharing and analytics marketplace. The HLTH.network aims to be the "world's first base layer protocol for global health data." In 2025, Church joined Lila Sciences, an AI agent platform startup, as Chief Scientist.
George Church Institute of Regenesis: collaboration with BGI Group, China
Since 2007, Church has served on the scientific advisory board of BGI Group.In 2017, BGI established the "George Church Institute of Regenesis", a research collaboration between Church's lab and about a dozen staffers at BGI in China. Dr. Xun Xu, executive director of BGI Group said:
On February 18, 2020, Nebula Genomics, a personal genomics company founded by Church, announced that had partnered up with BGI; the saliva samples sent to Nebula Genomics for decoding are then sent by the company to BGI labs in Hong Kong for sequencing. Nebula Genomics said that this partnership was made to bring down the cost of whole-genome sequencing, since normally it has a cost that makes it inaccessible to most people.
Research
Church is known for his professional contributions in the sequencing of genomes and interpreting such data, in synthetic biology and genome engineering, and in an emerging area of neuroscience that proposes to map brain activity and establish a "functional connectome". Church is known for pioneering the specialized fields of personal genomics and synthetic biology. He has co-founded commercial concerns spanning these areas, and others from green and natural products chemistry to infectious agent testing and fuel production, including Knome, LS9, and Joule Unlimited.Church and the foundation of genomics
With Walter Gilbert, Church published the first direct genomic sequencing method in 1984. Described in that publication were the cyclic application of fluids to a solid phase alternating with imaging, plus avoidance of bacterial cloning, strategies that are still used in current dominant Next-Generation Sequencing technologies. These technologies began to affect genome-scale sequencing in 2005. Church also helped initiate the Human Genome Project in 1984. He invented the broadly applied concepts of molecular multiplexing and barcode tags, and his genome was the fifth whole human genome ever sequenced. Church was the first person to make his medical records and genome publicly available to researchers. Technology transfer of automated sequencing and software from his Harvard laboratory to Genome Therapeutics Corp. resulted in the first bacterial genome sequence and first commercial genome in 1994. Church was co-inventor of nanopore sequencing in 1995, which is now commercially available, but not in the form embodied in Church's contribution to the original patents.To aid in the interpretation and sharing of genomes, Church initiated the Personal Genome Project in 2005, providing the world's only open-access human genome and trait data sets. Eight trios from the Personal Genome Project are in the process of being chosen to act as the primary genome standards for the NIST+FDA genomeinabottle.org program.
Church furthermore announced his intention to publish his DNA via NFT and use the profits made through its sale to finance research conducted by Nebula Genomics. In June 2022 20 NFTs with his likeness were published instead of the originally planned NFTs of his DNA due to the market conditions at the time. Despite leading to mixed reactions the project is considered to be part of an effort to use the genetic data of 15,000 individuals to support genetic research. By using NFTs the project wants to ensure that the users submitting their genetic data are able to receive direct payment for their contributions.
Synthetic biology and genome engineering
Church has co-developed "genome engineering" technologies since 1997 via either general homologous recombination or via sequence-specific nucleases. Since 2004, his team has developed the use of DNA array synthesizers for combinatorial libraries and assembling large genome segments. He co-developed Multiplex Automated Genome Engineering and optimized CRISPR/Cas9, discovered by Jennifer Doudna and Emmanuelle Charpentier for engineering a variety of genomes ranging from yeast to human. His laboratory's use of CRISPR in human induced pluripotent stem cells is the latest contender for precise gene therapy.His team is the first to tackle a genome-scale change in the genetic code. This was done in a 4.7 million basepair genome of an industrially useful microbe with the goal of making a safer and more productive strain; this strain uses non-proteinogenic amino acids in proteins, and is metabolically and genetically isolated from other species.
He has co-invented several uses for DNA, including detectors for dark matter – Weakly interacting massive particles, anti-cancer "nano-robots", and strategies for digital data storage that are over a million times denser than conventional disk drives. Together with polymerase, DNA can be used to sense and store variation in photons, nucleotides, or ions.
The BRAIN initiative
Church was part of a team who, in a 2012 scientific commentary, proposed a Brain Activity Map, later named BRAIN Initiative.They outlined specific experimental techniques that might be used to achieve what they termed a "functional connectome", as well as new technologies that will have to be developed in the course of the project, including wireless, minimally invasive methods to detect and manipulate neuronal activity, either utilizing microelectronics or synthetic biology. In one such proposed method, enzymatically produced DNA would serve as a "ticker tape record" of neuronal activity.
Gene therapy, ageing, and age reversal
Church worked on engineered adeno-associated viral vectors to evade innate immune and inflammatory responses. The research was published in Science Translational Medicine in 2021 and showed the possibility of a less immunogenic gene therapy with the new TLR9-edited Adeno-associated viruses as a safer viral vector. Based on the research, Church and a postdoc from his lab who was also the first-author of the research, co-founded Ally Therapeutics. In 2017, the Church lab at Harvard created adeno-associated virus -based single combination gene therapy "for simultaneous treatment of several age-related diseases", detailing the technology's efficacy in mitigating obesity, type II diabetes, heart failure, and renal failure in mice, and the work was published in PNAS. In early 2018, Rejuvenate Bio was launched from the Church lab at the Wyss Institute at Harvard to prevent and treat several age-related diseases in dogs, extending their overall lifespan. In the February 2020, Rejuvenate Bio, the company co-founded by Church, received an exclusive worldwide license from the Harvard Office of Technology Development to commercialise their gene therapy technology. As the co-founder of Rejuvenate Bio in an interview Church said:The research group's progress toward gene therapy for aging has been very limited, however. A 2022 PNAS paper from the Church group has already been the subject of two corrections, one for incomplete conflict of interest disclosures and one for image duplication.
Space biology and space genetics
Church is a faculty member in the Consortium of Space Genetics at Harvard Medical School.De-extinction, woolly mammoth revival project, and Colossal Biosciences
In March 2015, Church and his genetics research team at Harvard successfully copied some woolly mammoth genes into the genome of an Asian elephant. Using the CRISPR DNA editing technique, his group spliced genetic segments from frozen mammoth specimens, including genes from the ears, subcutaneous fat, and hair attributes, into the DNA of skin cells from a modern elephant. National Geographic, in an article titled "Mammoth-elephant hybrids could be created within the decade. Should they be?", reported:This marked the first time that woolly mammoth genes had been functionally active since the species became extinct. Their work has not been subject to peer review, however. Church stated that "Just making a DNA change isn't that meaningful. We want to read out the phenotypes." To do that, the team plans to perform further tests to get the hybrid cells into becoming specialized tissues, and from there attempting to turn the hybrid elephant/mammoth skin cells into hybrid embryos that can be grown in artificial wombs.
On September 13, 2021, Church founded a biosciences and genetics company, Colossal Biosciences, with entrepreneur Ben Lamm. The company is attempting to use genetic code to revive the woolly mammoth by equipping Asian elephants with mammoth traits.
Laetitia Garriott de Cayeux, founder-CEO of Global Space Ventures and an investor in Colossal Biosciences, said:
In 2013, in response to a question from Der Spiegel, Church speculated that it could be technically possible to make a Neanderthal by reconstructing its DNA and modifying living human cells accordingly. Translation issues and misreporting led some media outlets to believe that Church was working on such a project and searching for a surrogate mother, causing controversy. Church clarified that he was not.
In 2025, Colossal reported the live birth of two "dire wolves" where gray wolf cells received 20 unique gene edits, including 15 edits that directly matched dire wolf DNA and notably an edit that re-introduced pale coat color.
Technology transfer, translational impact, and serial entrepreneurship
Through his Harvard lab, Church has co-founded around 50 biotech companies, including Veritas Genetics, Warp Drive Bio, Alacris, Knome, Pathogenica, AbVitro, Gen9 Bio, EnEvolv, Joule Unlimited, LS9, and ReadCoor.Support of open consent
Church spearheaded the concept and implementation of open access sequencing hardware and shareable human medical data. He has noted the potential for re-identification of human research participants and the tendency for consent forms to be opaque – proposing an alternative "open consent" mechanism. He has participated in the Presidential Commission for the Study of Bioethical Issues, cautioning about the risk of synthetic DNA and proposing risk-reduction via licensing and surveillance. His laboratory has a major bio-safety engineering focus.Church's detailed online register of funding sources showed that he received funding from the nonprofit Jeffrey Epstein VI Foundation from 2005 to 2007. Church said in 2019 that he regrets he didn't know more about the donor.
Support of open education
Church is an advisor to the Personal Genetics Education Project and has spent a day teaching at The Jemicy School. He has promoted citizen science, especially in the fields of synthetic biology and personal genomics. Since 2008, his team has been hosting an annual Genomes, Environments and Traits Conference with free online videos.Rapid Deployment Vaccine Collaborative
Church is a member of the Rapid Deployment Vaccine Collaborative, a group formed early in the SARS-CoV-2 pandemic to create an easily produced, free and open-source vaccine for self-administration.Popular science
In his science and popular efforts, Church has promoted open access genome sequencing and shareable human medical data, as well as online, open education and citizen science.Church authored the 2012 New Scientist's "top science book", Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves with Ed Regis. He has participated in news interviews and videos including at TED, TEDx, and TEDMED venues, at PBS's Charlie Rose, Faces of America, and NOVA, as well as at PopSci, EG, and The Colbert Report. He is a regular contributor to Edge.org publications and videos and is a member of the Xconomists, an ad hoc team of editorial advisors for the tech news and media company, Xconomy.
In 2015, Jeneen Interlandi wrote an article on Church for Popular Science titled "The Church Of George Church: From reviving extinct species to hunting for dark matter, can a single scientist transform biology—and our lives?", where she states:
Awards and honors
Church has received accolades including election to the National Academy of Sciences, and the National Academy of Engineering. He received the American Society for Microbiology Promega Biotechnology Research Award and the Bower Award and Prize for Achievement in Science of the Franklin Institute. He authored the NewScientist "top science book", Regenesis with Ed Regis.Other honors include the Triennial International Steven Hoogendijk Award in 2010 and the Scientific American Top 50 twice. Newsweek picked Church for their 2008 "Power of Ideas" recognition in the category of Medicine. In September 2010, Church was honored for his work in genetics with the Mass High Tech All-Star Award.
He is a member of the Research Advisory Board of SENS Research Foundation.
Personal life
Church is married to fellow Harvard Medical School faculty member in genetics Ting Wu.Church has been outspoken in his support of following a vegan lifestyle, for reasons concerned with health, and with environmental and moral issues. When asked about his dietary choice, Church replied, "I've been vegan off-and-on since 1974 when I was inspired by participating in an MIT nutritional study, and quite strictly since 2004." He goes on to elaborate 4 reasons:
George identifies as a sentientist. Sentientism is a naturalistic worldview that grants moral consideration to all sentient beings.
In the context of the Personal Genome Project, journalists at Forbes and Wired have noted Church's openness about his health issues, including dyslexia, narcolepsy, and high cholesterol. Church has many of his best ideas during the brief naps caused by his narcolepsy, and therefore does not treat it.
Church collaborated with transhumanist entrepreneur James Clement on the Supercentenarian Research Study, which aims to sequence the genomes of supercentenarians in hopes of discovering potential genetic factors behind their longevity. As of 2023, he is part of the Enhanced Games scientific and ethical advisory commission.
