Jennifer Doudna

Editing genes was–and still is–uncharted territory. Scientists relied on slow, insufficient methods like homologous recombination to edit genes which limited the depth of genetic research. That was until Jennifer Doudna transformed modern biology with her breakthrough. Doudna was born on February 19th, 1964 and is an American biochemist who’s known for co-developing the CRISPR–Cas9 gene-editing technology. Her work revolutionized modern genetics by making genome editing more faster, efficient, accurate, and accessible for everyone. She came to be widely considered as one of the most influential scientists in the 21st century.

Jennifer Anne Doudna was born in Washington, D.C., and was raised in Hilo, Hawaii (Rogers, 2019). She became interested in science when she took her first Chemistry class in high school and participated in a science seminar series highlighting the chemistry of biological systems. Her parents were very supportive and encouraged her interests (Marino, 2004). She then attended Pomona College and graduated at the top of her class with a B.A in chemistry in 1985 (Rogers, 2019). Later, she completed her Ph.D at Harvard University in 1989, under Jack W. Szostak, focusing on catalytic RNA and did postdoctoral research at the University of Colorado Boulder with Thomas Cech, studying RNA structure and functions (Marino, 2004).

As a biochemist, Doudna made numerous impactful contributions to modern biology. Overall, she conducted critical research on RNA structure, catalysis, and biological function (Marino, 2004). Most notably, she co-developed CRISPR–Cas9 as a programmable, RNA-guided DNA-cutting tool with Emmanuelle Charpentier (The Nobel Prize in Chemistry 2020, n.d.). CRISPR–Cas9 is a gene-editing tool that uses a guide RNA to direct the Cas9 enzyme to a specific location in the DNA, where it then cuts the DNA. It’s used in genetic research to study the function of genes, develop new medicine, and to create new crops that are more resistant to pests (Medline, 2022). She even co-founded her own organization, the Innovative Genomics Institute, to advance applications of CRISPR in medicine, agriculture, and climate solutions (Innovative Genomics Institute, n.d). Consequently, she won multiple awards such as the Nobel Prize in Chemistry (2020) for the development of CRISPR–Cas9 and Breakthrough Prize in Life Sciences (The Nobel Prize in Chemistry 2020, n.d.). She was also elected to the National Academy of Sciences and is an Investigator of the Howard Hughes Medical Institute (HHMI, 2025).

Doudna made–and is continuing to make–a tremendous impact in the science community with her contributions. Thanks to her development of CRISPR–Cas9, she helped transform gene editing into a powerful and available tool used globally in biological editing (The Nobel Prize in Chemistry 2020, n.d.). It is now used to study genetic diseases, develop therapies, improve crops, and create new diagnostic technologies (Rogers, 2019). Her work was able to spark rapid growth in CRISPR-based biotech companies and clinical trials for gene-editing therapies (Sanders, 2020). However, controversy emerged with the creation of CRISPR–Cas9 with the community questioning its ethics. Consequently, Doudna advocated for ethical guidelines and transparency of gene editing (Rogers, 2019). But her impact in science goes beyond her development of CRISPR–Cas9. Through IGI, she supported research on equitable access to genetic technologies, including both food security and public health  (Innovative Genomics Institute, n.d). Overall, Jennifer Doudna has played a leading public role in discussions of future genome editing and its societal implications (Rogers, 2019).

Jennifer Doudna’s scientific work and achievements have reshaped biotechnology, medicine, and genetics for the better. CRISPR–Cas9 continues to influence science, industry, and society. Not only that, her leadership extends beyond the lab into ethics, public engaging, and global policy. Her work will continue to shape the future generations of
