Rob Knight (born 1976 in Dunedin, New Zealand) is a professor at the University of California, San Diego and the co-founder of the American Gut Project. He is also a co-founder of the Earth Microbiome Project. His lab’s research involves the development of laboratory and computational techniques to characterize the microbiomes of humans, animals, and the environment.
Knight completed a BSc in biochemistry at the University of Otago and a PhD at Princeton University on the Origin and Evolution of the Genetic Code in 2001. Until 2014, he was a professor at the University of Colorado – Boulder.
He did an IAmA on reddit and also taught a microbiome course on Coursera. He gave a TED Talk in 2014 on the role microbes play on our health. Later this idea was expanded into the book Follow Your Gut: The Enormous Impact of Tiny Microbes, written with science journalist Brendan Buhler and published by Simon & Schuster.
