Dr. Tim Hunt is the recipient, together with Leland H. Hartwell and Sir Paul M. Nurse, of the Nobel Prize for Physiology or Medicine in 2001 for discovering "Key regulators of the cell cycle". After receiving a Ph.D. from the University of Cambridge in 1968, Hunt went as a postdoctoral fellow to the Albert Einstein College of Medicine in New York. He returned to Cambridge in 1971, where he taught biochemistry and cell biology. In 1990 he moved to the Imperial Cancer Research Fund (now Cancer Research UK). Hunt’s research centred on cyclins, activating subunits of the Cyclin-Dependent protein Kinases (CDKs), which control cell cycle transitions. Hunt’s most recent work focused on the control of entry into and exit from mitosis. In addition to writing numerous scientific papers, he has served on editorial boards for several journals and was until recently Chairman of the Council of EMBO.
