He Jiankui. He is a Chinese biophysicist who gained international notoriety in 2018 for creating the world's first genetically edited babies. His work, which used the CRISPR-Cas9 technology to edit the CCR5 gene in human embryos to confer potential resistance to HIV, was conducted in secret and sparked a global firestorm of ethical, legal, and scientific condemnation. The experiment led to his criminal conviction in China and ignited enduring debates about the governance of human germline engineering and the future of reproductive technology.

Early life and education

He was born in 1984 in Xinhua county within Hunan province. He demonstrated strong academic prowess in physics, leading him to enroll at the prestigious University of Science and Technology of China in Hefei, where he earned a bachelor's degree in physics in 2006. For his doctoral studies, he moved to the United States, joining the research group of physicist Michael W. Deem at Rice University in Houston, Texas. His thesis work at Rice, completed in 2010, focused on DNA sequencing technology and genome analysis, laying a foundation in biophysics. He subsequently conducted postdoctoral research under the guidance of renowned bioengineer Stephen Quake at Stanford University in California, further immersing himself in the fields of genomics and bioengineering.

Career and research

Returning to China, He established his own research laboratory at the Southern University of Science and Technology (SUSTech) in Shenzhen, where he was appointed an associate professor. His research program initially focused on developing novel DNA sequencing techniques and investigating the genetics of complex traits. His work garnered some attention within the scientific community, and he secured funding from various sources, including the National Natural Science Foundation of China. During this period, he became deeply interested in the emerging and powerful gene-editing tool CRISPR-Cas9, exploring its potential applications. He also founded two biotechnology companies, Direct Genomics and Vienno Biotechnology, aiming to commercialize genetic testing and gene therapy technologies.

CRISPR baby controversy

In November 2018, at the Second International Summit on Human Genome Editing in Hong Kong, He announced that he had successfully used CRISPR-Cas9 to edit the CCR5 gene in human embryos before implantation. The stated goal was to make the resulting children, twin girls given the pseudonyms Lulu and Nana, resistant to infection by HIV, as their father was HIV-positive. The work was conducted without proper ethical oversight or transparency, bypassing established scientific norms and regulatory frameworks. The announcement was met with immediate and widespread shock and condemnation from the global scientific community, including prominent figures like Jennifer Doudna and Feng Zhang, pioneers of CRISPR technology. Major scientific bodies, including the United States National Academy of Sciences and the UK's Royal Society, denounced the experiment as irresponsible and premature.

Legal and ethical consequences

Following an official investigation by authorities in Guangdong province, He was found to have forged ethical review documents and violated numerous national regulations and ethical principles. In December 2019, he was convicted by the Shenzhen Nanshan District People's Court on charges of illegal medical practice. He was sentenced to three years in prison and fined three million yuan. Two of his collaborators, including his former advisor Zhang Renli and a reproductive physician, also received sentences. The court stated that He had pursued personal fame and gain while deliberately evading supervision. The case prompted China to swiftly draft and implement stricter regulations governing biomedical research and clinical trials, aiming to prevent similar ethical breaches.

Aftermath and legacy

Released from prison in 2022, He has largely remained out of the public eye, though reports indicate he has resumed some scientific research in Beijing. The long-term health effects on the gene-edited children remain unknown and are a subject of grave concern. The incident served as a global wake-up call, accelerating international discussions on establishing binding norms for heritable human genome editing. Organizations like the World Health Organization have since worked to develop global governance frameworks. The He Jiankui affair remains a seminal case study in bioethics, highlighting the profound risks of technological hubris, the critical importance of robust oversight, and the unresolved societal questions surrounding the modification of the human germline.
