Dr. Leland Hartwell is President and Director of Seattle’s Fred Hutchinson CancerResearch Center and Professor of Genome Sciences at the University of Washington.Dr. Hartwell’s primary research contributions were in identifying genes that controlcell division in yeast, including those necessary for the division process as well asthose necessary for the fi delity of genome reproduction. Subsequently, many of thesesame genes have been found to control cell division in humans and oft en to be thesite of alteration in cancer cells.Dr. Hartwell is a member of the National Academy of Sciences and has receivedthe Albert Lasker Basic Medical Research Award, the Gairdner… FoundationInternational Award, the Genetics Society Medal, and the 2001 Nobel Prize inPhysiology or Medicine.Dr. Michael Goldberg is a professor at Cornell University, where he teaches introductorygenetics and human genetics. He was an undergraduate at Yale Universityand received his Ph.D. in biochemistry from Stanford University. Dr. Goldberg performedpostdoctoral research at the Biozentrum of the University of Basel (Switzerland)and at Harvard University, and he received an NIH Fogarty Senior InternationalFellowship for study at Imperial College (England) and fellowships from theFondazione Cenci Bolognetti for sabbatical work at the University of Rome (Italy).His current research uses the tools of Drosophila genetics and the biochemical analysisof frog egg cell extracts to investigate the mechanisms that ensure proper cellcycle progression and chromosome segregation during mitosis and meiosis.
