Primary Information
Secondary Information

Definition

Jennifer Doudna is an American biochemist and molecular biologist who is known for her work on CRISPR-Cas9, a gene-editing technology that has the potential to revolutionize medicine and agriculture. Doudna is the co-founder of the CRISPR Therapeutics company, which is developing CRISPR-based therapies for diseases such as sickle cell anaemia and cancer.

Doudna was born in Washington, D.C., in 1964. She studied biochemistry at the University of California, Berkeley, and then went on to earn her PhD in molecular biology from Harvard University in 1990. After completing her doctorate, Doudna did postdoctoral research at the University of California, San Francisco, and then joined the faculty at the University of California, Berkeley, in 1994.

Doudna's research focuses on the mechanisms of DNA repair and genome editing. In 2012, she and Emmanuelle Charpentier, a French microbiologist, published a paper in the journal Science that described how CRISPR-Cas9 could be used to edit DNA. CRISPR-Cas9 is a natural bacterial defence mechanism that allows bacteria to fight off viruses. Doudna and Charpentier showed that CRISPR-Cas9 could be used to target and edit specific genes in human cells.

CRISPR-Cas9 has the potential to revolutionize medicine and agriculture. It could be used to cure diseases by editing out harmful genes. It could also be used to create new crops that are resistant to pests and diseases. CRISPR-Cas9 is still in its early stages of development, but it has the potential to change the world.

Doudna is a highly respected scientist and a pioneer in the field of gene editing. She has received numerous awards for her work, including the Breakthrough Prize in Life Sciences, the Lasker Award, and the Nobel Prize in Chemistry. She is a role model for young women scientists and an inspiration to everyone who believes in the power of science.
