Carol W. Greider

Carol W. Greider (born April 15, 1961) is an American molecular biologist. She completed her PhD in 1987 at the University of California, Berkeley, under Elizabeth Blackburn. Their research focused on telomeres, with which the ends of chromosomes are tipped, and they discovered the enzyme telomerase which replenishes the tips and determines the life span of the cell. For these discoveries, she shared the 2009 Nobel Prize in Physiology or Medicine with Blackburn and Jack W. Szostak.
