Carolyn Bertozzi

Carolyn Bertozzi. An American chemist and Nobel laureate renowned for pioneering the field of bioorthogonal chemistry, a transformative approach for studying biomolecules within living systems. Her work, which elegantly bridges organic chemistry and cell biology, has profoundly advanced understanding in glycobiology and enabled new applications in biomedical research and therapeutic development. She is a professor at Stanford University and an investigator at the Howard Hughes Medical Institute.

Early life and education

Born in Boston, she grew up in Lexington, Massachusetts, where her early interest in science was nurtured. Her father, William Bertozzi, was a professor of physics at the Massachusetts Institute of Technology. She completed her undergraduate studies at Harvard University, earning an A.B. in chemistry in 1988, where she conducted research in the laboratory of Joe Grabowski. For her doctoral work, she attended the University of California, Berkeley, receiving a Ph.D. in chemistry in 1993 under the supervision of Mark D. Bednarski, focusing on the chemical synthesis of oligosaccharide analogs. She subsequently performed postdoctoral research in cellular immunology at the University of California, San Francisco with Steven Rosen.

Academic career and research

Bertozzi began her independent career as a faculty member at the University of California, Berkeley in 1996, holding joint appointments in the Department of Chemistry and the Department of Molecular and Cell Biology. In 2015, she moved to Stanford University, where she is the Anne T. and Robert M. Bass Professor in the School of Humanities and Sciences. Her research laboratory has consistently worked at the interface of chemistry and biology, developing chemical tools to interrogate glycosylation, a fundamental but complex biological process. Her work has significant implications for understanding inflammation, cancer, and infectious diseases like tuberculosis. She has also been a long-term investigator with the Howard Hughes Medical Institute and founded several biotechnology companies, including Redwood Bioscience and Palleon Pharmaceuticals.

Development of bioorthogonal chemistry

Bertozzi's most celebrated contribution is the invention and development of bioorthogonal chemistry, a suite of chemical reactions that can occur inside living organisms without interfering with native biochemical processes. This concept emerged from her desire to image glycans on the surface of living cells. She pioneered reactions like the Staudinger ligation and, later, copper-free variants of click chemistry, such as the strain-promoted azide-alkyne cycloaddition. These tools allow scientists to label and track biomolecules in real-time within their native environments, revolutionizing fields like chemical biology, molecular imaging, and drug delivery. Her work in this area was foundational to the award of the Nobel Prize in Chemistry in 2022, which she shared with Morten Meldal and Karl Barry Sharpless.

Awards and honors

Bertozzi has received extensive recognition for her scientific achievements. She was awarded a MacArthur Fellowship in 1999. Major honors include the Lemelson–MIT Prize, the Heinrich Wieland Prize, and the Wolf Prize in Chemistry in 2022. She is a member of the National Academy of Sciences, the National Academy of Medicine, and the American Academy of Arts and Sciences. In 2022, she was co-awarded the Nobel Prize in Chemistry for the development of click chemistry and bioorthogonal chemistry. She has also received prestigious awards such as the ACS Award in Pure Chemistry, the Ernest Orlando Lawrence Award, and the F. A. Cotton Medal.

Personal life

She is openly gay and has been an advocate for LGBTQ+ inclusion in the sciences. In her personal time, she is a musician and has played in a band named Bored of Education with fellow graduate students at UC Berkeley. She is also known for her mentorship and commitment to promoting diversity within the fields of chemistry and biochemistry.
