Jennifer Doudna

Jennifer Anne DoudnaForMemRS (; born February 19, 1964) is an American biochemist who has pioneered work in , and made other fundamental contributions in biochemistry and genetics. She received the 2020 Nobel Prize in Chemistry, with Emmanuelle Charpentier, "for the development of a method for genome editing." She is the Li Ka Shing Chancellor's Chair Professor at the University of California, Berkeley. She has been an investigator with the Howard Hughes Medical Institute since 1997.

In 2012, Doudna and Emmanuelle Charpentier were the first to propose that CRISPR-Cas9 (enzymes from bacteria that control microbial immunity) could be used for programmable editing of genomes, which has been called one of the most significant discoveries in the history of biology. Since then, Doudna has been a leading figure in what is referred to as the "CRISPR revolution" for her fundamental work and leadership in developing CRISPR-mediated .

Doudna's awards and fellowships include the 2000 Alan T. Waterman Award for her research on the structure of a ribozyme, as determined by X-ray crystallography and the 2015 Breakthrough Prize in Life Sciences for CRISPR-Cas9 genome editing technology, with Charpentier. She has been a co-recipient of the Gruber Prize in Genetics (2015), the Tang Prize (2016), the Canada Gairdner International Award (2016), and the Japan Prize (2017). She was named one of the Time 100 most influential people in 2015, and in 2023 was inducted into the National Inventors Hall of Fame.
