Jennifer A. Doudna
Jennifer A. Doudna (1964), a biochemist and molecular biologist, shared the 2020 Nobel Prize in Chemistry for development of the genome-editing technique CRISPR-Cas9, which has revolutionized many fields of science and medicine. Her discovery was the outcome of a curiosity-driven experiment to understand how bacteria fight viruses. Applications of CRISPR in biology and the treatment of disease have enormous potential but raise many ethical and safety concerns, so Doudna works to raise awareness of the ethical dangers of the technology. She is a member of the National Academy of Sciences.
