Three Scientists From The United States And Britain Share The 2019 Nobel Prize In Physiology Or Medicine

The 2019 Nobel Prize in physiology or medicine has been awarded to William g. Kaelin, Sir Peter j. Ratcliffe and Gregg.


The 2019 Nobel Prize will be awarded to three scientists who revolutionized the understanding of how cells sense oxygen at the molecular level, the karolinska institute of medicine announced Wednesday in Stockholm. The discovery sheds light on one of life’s most important adaptive mechanisms, laying the foundation for understanding how oxygen levels affect cell metabolism and physiological function and potentially paving the way for new strategies to fight anemia, cancer and many other diseases.

All three winners were born in the 1950s and have spent almost their entire lives in medical research, waiting long hours for results to be tested and winning numerous awards.

William g. Kaelin, Jr. Was born in 1957 in New York. He received an m.d. from duke university and specialized training in internal medicine and oncology at Johns Hopkins university and the Dana farber cancer institute. She set up her own research laboratory at the dana-farber cancer institute and became a professor at harvard medical school in 2002. He has been a Howard hughes medical institute researcher since 1998.


Born in Lancashire in 1954, Sir Peter j. Ratcliffe studied medicine at gonville and caius college, Cambridge, and received specialist training in nephrology at Oxford University. He set up an independent research group at Oxford University and became a professor in 1996. He is director of clinical research at the Francis crick institute, director of the target discovery institute, and a member of the Ludwig cancer institute.

Gregg l. Semenza was born in 1956 in New York. He received a bachelor’s degree in biology from Harvard University. In 1984, he received his PhD from the university of Pennsylvania school of medicine and trained as a pediatric specialist at duke university. He went on to do postdoctoral training at Johns Hopkins university and set up an independent research group. He became a full professor at Johns Hopkins university in 1999 and has been director of the vascular research program at the Johns Hopkins institute of cell engineering since 2003.
