Paul Knoepfler is a biologist and genomics researcher at the UC Davis School of Medicine who is also interested in bioethics and policy research. For more than eight years, he has been running “The Niche,” a blog on stem cells and other cutting-edge life science technologies that in part serves as a check on predatory, for-profit stem cell clinics. He helped to develop the new California law on stem cell clinics that requires the businesses to post notices to patients. His TED talk on the potential use of CRISPR in humans to make designer babies has had more than 1.2 million views. He was also recently on Bill Nye’s new show as a guest panelist on the same topic. He has written two books: Stem Cells: An Insider’s Guide and GMO Sapiens: The Life-Changing Science of Designer Babies. In addition to his own science writing, he is a go-to biologist for science journalists.
