William G. Kaelin Jr.

William G. Kaelin Jr. is an American cancer researcher known for his groundbreaking work on how cells respond to oxygen levels. His research has helped explain how cancer cells can adapt to low oxygen environments, a process that supports tumor growth. Kaelin's discoveries have significant implications for understanding cancer biology and developing new treatments. In 2019, he was awarded the Nobel Prize in Physiology or Medicine, alongside two colleagues, for their contributions to the field of cellular oxygen sensing. His work continues to influence cancer research and therapies, aiming to improve patient outcomes.
