CRISPR is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and destroy DNA from similar bacteriophages during subsequent infections. Hence these sequences play a key role in the antiviral defense system of prokaryotes and provide a form of acquired immunity. CRISPR is found in approximately 50% of sequenced bacterial genomes and nearly 90% of sequenced archaea.

Through his Harvard lab Church has co-founded around 50 biotech companies pushing the boundaries of innovation in the world of life sciences and making his lab as a hotbed of biotech startup activity in Boston. In 2018, the Church lab at Harvard made a record by spinning off 16 biotech companies in one year. The Church lab works on research projects that are distributed in diverse areas of modern biology like developmental biology, neurobiology, info processing, medical genetics, genomics, gene therapy, diagnostics, chemistry & bioengineering, space biology & space genetics, and ecosystem. Research and technology developments at the Church lab have impacted or made direct contributions to nearly all "next-generation sequencing (NGS)" 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, and was listed among the top 8 famous geneticists of all time in human history. As of January 2023, Church serves as a member of the Bulletin of the Atomic Scientists' Board of Sponsors.

Editas Medicine, Inc.,, is a clinical-stage biotechnology company which is developing therapies for rare diseases based on CRISPR gene editing technology. Editas headquarters is located in Cambridge, Massachusetts and has facilities in Boulder, Colorado.
Intellia Therapeutics, Inc. is an American clinical-stage biotechnology company focused on developing novel, potentially curative therapeutics leveraging CRISPR-based technologies. The company's in vivo programs use intravenously administered CRISPR as the therapy, in which the company's proprietary delivery technology enables highly precise editing of disease-causing genes directly within specific target tissues. Intellia's ex vivo programs use CRISPR to create the therapy by using engineered human cells to treat cancer and autoimmune diseases.
Rachel Elizabeth Haurwitz is an American biochemist and structural biologist. She is the co-founder, chief executive officer, and president of Caribou Biosciences, a genome editing company.
CRISPR gene editing is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial CRISPR-Cas9 antiviral defense system. By delivering the Cas9 nuclease complexed with a synthetic guide RNA (gRNA) into a cell, the cell's genome can be cut at a desired location, allowing existing genes to be removed and/or new ones added in vivo.
Janice Chen is co-founder and chief technology officer of Mammoth Biosciences, a Brisbane, California-based company founded in 2018 that is developing diagnostic tests using CRISPR. She received her B.S. degree from Johns Hopkins University and as a graduate student at the University of California, Berkeley, she worked in the lab of CRISPR pioneer Jennifer Doudna, receiving her PhD in Molecular and Cell Biology.
Locus Biosciences is a clinical-stage pharmaceutical company, founded in 2015 and based in Research Triangle Park, North Carolina. Locus develops phage therapies based on CRISPR–Cas3 gene editing technology, as opposed to the more commonly used CRISPR-Cas9, delivered by engineered bacteriophages. The intended therapeutic targets are antibiotic-resistant bacterial infections.
A coronavirus breathalyzer is a diagnostic medical device enabling the user to test with 90% or greater accuracy the presence of severe acute respiratory syndrome coronavirus 2 in an exhaled breath. As of the first half of 2020, the idea of a practical coronavirus breathalyzer was concomitantly developed by unrelated research groups in Australia, Canada, Finland, Germany, Indonesia, Israel, Netherlands, Poland, Singapore, United Kingdom and USA.
Flagship Pioneering is an American life sciences venture capital company based in Cambridge, Massachusetts that invests in biotechnology, life sciences, health and sustainability companies.
