After attending Magdalen College School (Oxford) Hunt received his PhD from the University of Cambridge in 1968. While doing summer work in 1982 at the Marine Biological Laboratory at Woods Hole, Massachusetts, Hunt made his most important discovery. Using the sea urchin (Arbacia punctulata) egg as his model organism, he discovered the cyclin molecule. Hunt found that cyclins are at increased levels during interphase, then drop quickly about 10 minutes before each cell division. He also found that cyclins are present in other animals, and regulate cell cycle in these animals as well. In 1991, he began work at Imperial Cancer Research Fund in South Mimms, United Kingdom. He became a fellow of the Royal Society in 1991 and a foreign associate of the U.S. National Academy of Sciences in 1999.
