Jennifer Doudna
American biochemist who co-developed CRISPR-Cas9 genome editing.
Jennifer Doudna, born February 19, 1964, in Washington, D.C., is an American biochemist best known for her foundational work on CRISPR gene editing. She shared the 2020 Nobel Prize in Chemistry with Emmanuelle Charpentier for developing a method to edit genomes. Doudna holds the Li Ka Shing Chancellor’s Chair Professorship at the University of California, Berkeley, and has been a Howard Hughes Medical Institute investigator since 1997. In 2012, she and Charpentier first proposed that CRISPR-Cas9—bacterial enzymes involved in microbial immunity—could be used to programmably edit genomes, a breakthrough often called one of biology’s most significant. This kicked off what is known as the “CRISPR revolution,” with Doudna as a leading figure.
Her early life was shaped by a move to Hilo, Hawaii, when she was seven, after her father took a teaching job at the University of Hawaii at Hilo. Her mother, who held a master’s in education, later earned a second master’s in Asian history and taught at a community college. Doudna’s fascination with local flora and fauna, along with her father’s popular science books, sparked her curiosity. In sixth grade, he gave her James Watson’s *The Double Helix*, a major inspiration. At Hilo High School, her 10th-grade chemistry teacher, Jeanette Wong, and a visiting lecturer on cancer cells encouraged her science career. She spent a summer in mycologist Don Hemmes’s lab at the University of Hawaii at Hilo, graduating in 1981.
Doudna studied biochemistry at Pomona College in Claremont, California. During her freshman year, she doubted her ability to pursue science and considered switching to French, but her French teacher advised her to stay. Chemistry professors Fred Grieman and Corwin Hansch influenced her, and she began research in Sharon Panasenko’s lab. She earned a BA in biochemistry in 1985, then a PhD in biological chemistry and molecular pharmacology from Harvard Medical School in 1989, supervised by Jack W. Szostak, on a system that boosted a self-replicating catalytic RNA’s efficiency.
After her PhD, she held research fellowships at Massachusetts General Hospital and Harvard Medical School. From 1991 to 1994, she was a Lucille P. Markey Postdoctoral Scholar at the University of Colorado Boulder, working with Thomas Cech. As of 2025, her h-index is 166 on Google Scholar and 134 on Scopus. Early in her career, Doudna focused on RNA enzymes (ribozymes). In Szostak’s lab, she re-engineered a self-splicing Tetrahymena Group I intron into a true catalytic ribozyme that copied RNA templates. Realizing that not seeing ribozyme molecular mechanisms was a problem, she went to Cech’s lab to crystallize and determine the first three-dimensional structure of a ribozyme, starting in 1991 and finishing at Yale University in 1996. She joined Yale’s Department of Molecular Biophysics and Biochemistry as an assistant professor in 1994.
At Yale, her group crystallized and solved the structure of the Tetrahymena Group I ribozyme’s catalytic core, showing five magnesium ions clustered in one region of the P4-P6 domain, forming a hydrophobic core around which the rest folded—analogous to, but chemically distinct from, protein hydrophobic cores. They also crystallized other ribozymes, like the Hepatitis Delta Virus ribozyme. This work led to further structural studies.
Doudna’s awards include the 2000 Alan T. Waterman Award for her ribozyme structure research via X-ray crystallography, and the 2015 Breakthrough Prize in Life Sciences with Charpentier for CRISPR-Cas9. She has co-received the Gruber Prize in Genetics (2015), the Tang Prize (2016), the Canada Gairdner International Award (2016), and the Japan Prize (2017). *Time* named her one of the 100 most influential people in 2015, and she was inducted into the National Inventors Hall of Fame in 2023.

Verified Timeline
Lore & Background
Jennifer Doudna was born February 19, 1964, in Washington, D.C., to Dorothy Jane (Williams) and Martin Kirk Doudna. When she was seven, the family moved to Hawaii so her father could teach American literature at the University of Hawaii at Hilo. Growing up in Hilo, she was fascinated by its flora and fauna. In sixth grade, her father gave her James Watson's 1968 book *The Double Helix*, which was a major inspiration. Her 10th-grade chemistry teacher, Jeanette Wong, encouraged her interest in science. She graduated from Hilo High School in 1981. Doudna studied biochemistry at Pomona College, earning a Bachelor of Arts in 1985, and earned a Ph.D. in biological chemistry and molecular pharmacology from Harvard Medical School in 1989, supervised by Jack W. Szostak. After postdoctoral work at the University of Colorado Boulder with Thomas Cech, she joined Yale University as an assistant professor in 1994. At Yale, her group crystallized and solved the three-dimensional structure of the catalytic core of the Tetrahymena Group I ribozyme. She moved to the University of California, Berkeley in 2002. In 2012, Doudna and Emmanuelle Charpentier first proposed that CRISPR-Cas9 could be used for programmable editing of genomes. She directs the Innovative Genomics Institute, a collaboration between Berkeley and UCSF.
Reader's Guide
Jennifer Doudna's significance stems from her co-discovery that the bacterial CRISPR-Cas9 system could be programmed to edit genomes, a breakthrough widely considered one of the most significant in the history of biology. This discovery, made with Emmanuelle Charpentier in 2012, transformed genetic research and opened new avenues for treating diseases including sickle cell anemia, cystic fibrosis, Huntington's disease, and HIV. Doudna's earlier work on ribozyme structure, including solving the three-dimensional structure of the catalytic core of the Tetrahymena Group I ribozyme, established her as a leading structural biologist. Her awards include the 2020 Nobel Prize in Chemistry, the 2015 Breakthrough Prize in Life Sciences, the 2000 Alan T. Waterman Award, and induction into the National Inventors Hall of Fame in 2023. She has also been a prominent voice on the ethics of genome editing, calling for a worldwide moratorium on clinical application of gene editing using CRISPR and supporting its use in somatic but not germline editing. Her legacy is defined by her role in launching the CRISPR revolution and her ongoing leadership in developing genome editing technology for human health, agriculture, and climate change.
