Jennifer Anne Doudna (born February 19, 1964) is an American biochemist whose scientific career has reshaped the landscape of modern biology. Together with French microbiologist Emmanuelle Charpentier, Doudna proposed in 2012 that the bacterial immune system known as CRISPR-Cas9 could be repurposed as a programmable tool for editing the genomes of living organisms — a discovery that has been described as one of the most significant in the history of biology. For this work, Doudna and Charpentier were awarded the 2020 Nobel Prize in Chemistry "for the development of a method for genome editing." Doudna holds the Li Ka Shing Chancellor's Chair Professorship in the Department of Chemistry and the Department of Molecular and Cell Biology at the University of California, Berkeley, and has served as an investigator with the Howard Hughes Medical Institute since 1997. Beyond her laboratory research, Doudna has become a central figure in the broader societal conversation about the ethical implications of gene editing and has pursued efforts to make CRISPR-based therapies accessible to wider populations.

Early Life

Jennifer Anne Doudna was born on February 19, 1964, in Washington, D.C. She grew up in Hilo, Hawaii, where her family relocated during her childhood. According to accounts of her formative years, Doudna struggled with finding her way through school before ultimately pursuing a career in science. Growing up in Hawaii, surrounded by the unique biological diversity of the islands, contributed to her early curiosity about the natural world and the molecular mechanisms underlying life.

Doudna's path to becoming a scientist was not straightforward. As a young student, she faced challenges common to many who eventually find their calling in research — uncertainty about her academic direction and the difficulty of identifying a clear path forward in a field that can seem inaccessible. These early experiences of navigating academic life would later inform her perspective as a mentor and advocate for young scientists, particularly women in STEM fields.

Her interest in chemistry and biochemistry developed over time, ultimately leading her to pursue higher education on the mainland United States. The transition from the relatively isolated environment of Hilo to the rigors of university study in the sciences marked a formative period in Doudna's intellectual development.

Education

Doudna pursued her undergraduate education and went on to earn her Ph.D. from Harvard University, where she conducted graduate research in biochemistry. Her doctoral work focused on the study of RNA molecules, laying the foundation for her later research into the structural biology of ribozymes and, eventually, the CRISPR-Cas9 system. Her graduate training at Harvard placed her within one of the foremost centers of molecular biology research in the world, providing her with the technical skills and intellectual framework that would define her subsequent career.

Following the completion of her doctorate, Doudna conducted postdoctoral research that deepened her expertise in RNA biochemistry and structural biology, particularly the use of X-ray crystallography to determine the three-dimensional structures of biologically important molecules.

Career

Early Research and RNA Structural Biology

Doudna's early independent career focused on the structural biology of RNA molecules, particularly ribozymes — RNA molecules capable of catalyzing chemical reactions. Using X-ray crystallography, she determined the structure of ribozymes, work that provided fundamental insights into how RNA can function as both a carrier of genetic information and a catalyst of biochemical reactions. This research earned her the Alan T. Waterman Award in 2000, given by the National Science Foundation to an outstanding young researcher.

Doudna joined the faculty of the University of California, Berkeley, where she established a laboratory that became a leading center for the study of RNA biology and structural biochemistry. She was also appointed as an investigator of the Howard Hughes Medical Institute in 1997, a position that provided significant and sustained research support for her laboratory's work.

Her structural biology work during this period extended to understanding the mechanisms by which RNA molecules fold into complex three-dimensional shapes and interact with proteins. These studies provided a critical foundation for her later work on CRISPR, as the CRISPR-Cas9 system relies on RNA molecules to guide the Cas9 protein to specific locations in the genome.

Discovery of CRISPR-Cas9 as a Genome Editing Tool

The work for which Doudna is best known began in the early 2010s, when she turned her attention to the CRISPR system — a naturally occurring defense mechanism found in bacteria and archaea. CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) functions as a form of adaptive immunity in microorganisms, allowing them to recognize and destroy the DNA of invading viruses.

In 2012, Doudna and Emmanuelle Charpentier published a landmark paper demonstrating that the CRISPR-Cas9 system could be reprogrammed to cut DNA at specific, predetermined sites in a genome. Their key insight was that the Cas9 protein, guided by a short piece of RNA that could be engineered to match virtually any DNA sequence, could serve as a precise molecular tool for genome editing. This discovery transformed biology by providing researchers with an accessible, efficient, and relatively inexpensive method for making targeted changes to the DNA of any organism, from bacteria to human cells.

The simplicity and versatility of the CRISPR-Cas9 system set it apart from previous genome editing technologies, such as zinc finger nucleases and TALENs. Within months of the 2012 publication, laboratories around the world adopted CRISPR-Cas9 for a vast range of applications, including basic biological research, agricultural improvement, and the development of potential therapies for genetic diseases.

Doudna described the significance of the CRISPR-Cas9 discovery and its applications in her 2026 Priestley Medal address to the American Chemical Society, titled "The Chemistry of Genome Editing: Transforming Human and Planet Health with CRISPR."

CRISPR Patent Dispute

The development of CRISPR-Cas9 as a genome editing tool led to a prolonged and high-profile patent dispute. The dispute centered on competing patent claims between Doudna's group at the University of California, Berkeley, and a team led by Feng Zhang at the Broad Institute of MIT and Harvard. The case drew considerable attention within the scientific community and in the broader public, as the patents held significant commercial implications for the biotechnology and pharmaceutical industries.

Commercial Ventures and Translational Work

Beyond her academic research, Doudna has been actively involved in efforts to translate CRISPR technology into practical applications, particularly in medicine. She co-founded several biotechnology companies aimed at developing CRISPR-based therapies, including Caribou Biosciences, a company focused on applying CRISPR technology to develop new medicines.

In 2026, Doudna announced an ambitious plan to bring CRISPR-based gene editing treatments to broader populations. According to reporting by Forbes, the initiative involves a $1 billion plan to address the commercial challenges that have slowed the translation of CRISPR technology from laboratory research into approved medical therapies. CRISPR's ability to cut genetic code with precision has begun to produce new medicines, but significant obstacles remain in scaling these treatments and making them affordable. Doudna's plan aims to overcome these barriers and accelerate the development of gene editing therapies for a wider range of diseases.

Ethics and Public Engagement

Doudna has been a prominent voice in discussions about the ethical implications of genome editing technology. Following the publication of her CRISPR-Cas9 work, she played an active role in calling for a broad societal conversation about the appropriate uses and potential risks of gene editing, particularly as applied to human germline cells — changes that would be passed on to future generations. Her public engagement on these issues has included lectures, writings, and participation in scientific conferences and policy discussions.

In September 2025, Doudna delivered a public lecture at the Cleveland Museum of Natural History titled "The Science of CRISPR," in which she discussed the development of CRISPR-Cas9 as a genome engineering technology and its implications for science and society.

She has also continued to engage with the University of California, Berkeley community. In August 2025, she participated in a conversation for the "Berkeley Talks" podcast, discussing CRISPR and the future of gene editing.

Mentorship

In addition to her research contributions, Doudna has been recognized for her role as a mentor to younger scientists. Her own experiences navigating the challenges of academic life — including her struggles as a student before finding her path in science — have informed her approach to supporting the next generation of researchers. Her mentorship has extended to training numerous graduate students and postdoctoral fellows who have gone on to establish their own independent research programs in fields related to gene editing and RNA biology.
