Carolyn found a way to study these sugars. She does this without stopping how the cell works. This is a big discovery.

Her work helps us learn about being sick. It can help fight diseases like cancer. She even helped make a test for a lung sickness.

She won a very big prize called the Nobel Prize. Her work is very important to science.

Carolyn Bertozzi is a famous chemist. She studies how living things work.

She is a Nobel laureate. This is a very big prize for science.

Carolyn studies sugars on the surface of cells. These sugars are called glycans. They act like a coating. This coating helps cells talk to each other. It also helps them recognize each other.

She found a new way to study these sugars. She calls this bioorthogonal chemistry. This means she can change molecules inside a living thing. She does this without stopping the cell's normal work. This is very important for science.

Her work helps us understand many diseases. She studies cancer and viruses like COVID-19. Her lab even made a fast test for tuberculosis. This is a sickness in the lungs.

Carolyn went to Harvard University. Later, she earned her Ph.D. at UC Berkeley. She now teaches at Stanford University. She has also started many companies to help make new medicines. Her work helps doctors fight disease in new ways.

Carolyn Bertozzi is a famous American chemist. She studies how living things work at a very tiny level.

Her work covers both chemistry and biology. She is a Nobel laureate, which is one of the highest honors in science. This means her discoveries changed how we understand life. She is also a professor at Stanford University. She works to find new ways to fight many different diseases.

Bertozzi focuses on a special area called glycobiology. This is the study of sugars on the outside of cells. These sugars are called glycans. They form a coating around a cell. This coating helps cells talk to each other. It also helps cells recognize their neighbors. Bertozzi found that viruses can use these sugars to bind to the body. This is how some sicknesses start to spread.

To study these sugars, she created bioorthogonal chemistry. This is a special way of doing chemical reactions inside living systems. Usually, adding chemicals can stop a cell from working. Bioorthogonal chemistry is different because it does not interrupt the cell. It allows scientists to change molecules without breaking the natural processes. This makes it possible to watch how a living cell behaves in real time. It is like fixing a car engine while the car is still driving.

Her journey in science began at Harvard University. She studied chemistry there and won a special thesis prize. Later, she earned her Ph.D. at the University of California, Berkeley in 1993. While at Berkeley, she made a big discovery about viruses and sugars. She also worked at the University of California, San Francisco. In 1996, she became a faculty member at UC Berkeley. Since 2015, she has been part of the team at Stanford University.

Her tools help doctors treat many hard jobs in medicine. For example, her lab helped create a fast test for tuberculosis in 2018. She also studies how cancer cells use sugar coatings to hide from the immune system. This work helps us understand diseases like arthritis and COVID-19. Bertozzi has even started several companies to turn her ideas into real medicines. Her work connects the tiny world of molecules to the big world of human health.

Carolyn Ruth Bertozzi is a renowned American chemist and Nobel laureate. Her work bridges the gap between chemistry and biology. She is a professor at Stanford University within the School of Humanities and Sciences. Bertozzi is also an Investigator at the Howard Hughes Medical Institute. Her research focuses on the complex interactions between molecules and living systems. She is particularly famous for creating a new way to study life through chemistry.

Bertozzi pioneered a field called bioorthogonal chemistry. This term describes chemical reactions that are compatible with living systems. In a normal laboratory setting, adding chemicals to a cell can be disruptive. These chemicals might kill the cell or stop its natural functions. Bioorthogonal chemistry allows scientists to modify molecules inside a living organism without interrupting its processes. This means researchers can observe or change specific parts of a cell while it continues to live and work. This breakthrough allows for a much more accurate look at biological life.

Her specific area of study is known as glycobiology. This is the science of glycans, which are complex sugars found on the surfaces of cells. These glycans form a coating called a glycocalyx around the cell membrane. This sugar coating is vital for cell recognition and communication between cells. Bertozzi uses her chemical tools to study how these sugars affect various diseases. She investigates how glycans play a role in cancer, inflammation, and viral infections like COVID-19. Her work helps reveal how cells use these sugar messages to function or fail.

Bertozzi's scientific journey began with a strong foundation in chemistry. She attended Harvard University, where she earned her B.A. summa cum laude. During her time there, she worked on a photoacoustic calorimeter. This project earned her the Thomas T. Hoopes Undergraduate Thesis Prize. After Harvard, she worked at Bell Labs before moving to the University of California, Berkeley. She completed her Ph.D. in 1993 under the supervision of Mark Bednarski. While at Berkeley, she discovered that viruses can bind to the sugars in the human body. This specific discovery helped define her future research path in glycobiology.

Her career includes many significant leadership roles and honors. In 1996, she became a faculty member at the UC Berkeley College of Chemistry. She also served as the director of the Molecular Foundry at Lawrence Berkeley National Laboratory. In 2015, she moved to Stanford University to join the ChEM-H Institute. In 2022, she was awarded the Nobel Prize in Chemistry. She shared this honor with Morten P. Meldal and Karl Barry Sharpless. This prize recognized their collective development of click chemistry and bioorthogonal chemistry.

Bertozzi has also turned her scientific discoveries into practical medical tools. Her laboratory developed nanotechnologies that can probe biological systems. In 2018, this research led to a fast point-of-care test for tuberculosis. She has also co-founded several biotechnology companies to advance medical treatments. For example, Redwood Bioscience uses a technology called SMARTag to attach drugs to specific proteins. Her company Lycia Therapeutics focuses on lysosome-targeting chimeras, known as LYTACs. These molecules may help degrade targets involved in cancer and cardiovascular disease. These innovations aim to move discoveries from the lab directly to patients.

Beyond the laboratory, Bertozzi is a leader in the scientific community. She has been a member of the National Academy of Sciences since 2005. She also joined the Institute of Medicine in 2011 and the National Academy of Inventors in 2013. In 2014, she was named the leader of ACS Central Science, an open-access journal. Her influence extends to many different sectors of biotechnology and pharmaceutical research. Through her teaching, her research, and her companies, she continues to shape the future of medicine.
