George McDonald Church, born on August 28, 1954, on MacDill Air Force Base in Tampa, Florida, developed an early interest in mathematics, mineralogy, and entomology, alongside a fascination with computers. After attending Phillips Academy, he pursued a Bachelor of Science in zoology and chemistry at Duke University in two years. His initial research at Duke, focusing on X-ray crystallography, combined his interests in computers and biology, leading to his first peer-reviewed publication in 1977. Church then continued his graduate studies at Harvard University under Walter Gilbert, earning a Ph.D. in biochemistry and molecular biology in 1984. During his doctoral work, he contributed to understanding introns’ regulatory function in mitochondrial genomes and developed a method for direct genomic sequencing, which bypassed the need for bacterial cloning.
After a brief period at Biogen and a postdoctoral fellowship at the University of California, San Francisco, Church joined Harvard Medical School as an assistant professor in 1986. Throughout his career, he has been credited with numerous innovations that have shaped modern biotechnology. In 1984, he co-developed the first direct genomic sequencing method and was instrumental in initiating the Human Genome Project. He also introduced molecular multiplexing and barcode tags and co-invented nanopore sequencing in 1995. In 2005, he launched the Personal Genome Project to make human genomic and trait data publicly accessible, fostering a new era of personal genomics. Church’s laboratory has been a hub for translational research, leading to the co-founding of over 50 biotech companies. His contributions extend to synthetic biology, where he co-developed Multiplex Automated Genome Engineering (MAGE) and optimized CRISPR/Cas9 for genome editing, and has explored genome-scale changes for industrial and therapeutic applications.
His research spans diverse areas including developmental biology, neurobiology, medical genetics, aging, and space biology. Notably, Church is recognized for his work on gene therapy for age-related diseases, including co-founding Rejuvenate Bio. A significant and recent venture is Colossal Biosciences, co-founded in 2021, which aims at de-extinction, including the woolly mammoth revival project using genetic engineering. Through his extensive academic roles, including Robert Winthrop Professor of Genetics at Harvard Medical School and Professor of Health Sciences and Technology at Harvard and MIT, and his entrepreneurial endeavors, Church continues to drive innovation at the intersection of genetics, engineering, and medicine.
