John Wilson received his PhD from the California Institute of Technology and did his postdoctoral work at Stanford University. He is currently Professor of Biochemistry and Molecular Biology at Baylor College of Medicine, with research interests in genome stability and gene therapy. He has taught medical and graduate students for many years, co authored books on immunology, molecular biology, and biochemistry, and received numerous teaching honors, including the Distinguished Faculty and Robertson Presidential Awards for excellence in education. Tim Hunt received his PhD in biochemistry from Cambridge University, where he supervised undergraduates in cell biology for more than 20 years. He spent many summers in the late 1970s and early 1980s teaching molecular biology at the Marine Biological Laboratories in Woods Hole, Massachusetts. In 1990, he moved to a position at ICRF Clare Hall Laboratories just outside London, where he works on the control of the cell cycle. He is a Fellow of The Royal Society of London and a foreign associate of the US National Academy of Sciences. In recognition of his contribution to the discovery of key regulators of cell cycle, he was one of the recipients of the 2001 Nobel Prize for Physiology or Medicine.
