Dr. Randy Schekman is a Professor in the Department of Molecular and Cell Biology, University of California, Berkeley, and an Investigator of the Howard Hughes Medical Institute. He studied the enzymology of DNA replication as a graduate student with Arthur Kornberg at Stanford University. His current interest in cellular membranes developed during a postdoctoral period with S. J. Singer at the University of California, San Diego. At Berkeley, he developed a genetic and biochemical approach to the study of eukaryotic membrane traffic. Among his awards are the Eli Lilly Award in microbiology and immunology, the Lewis S. Rosenstiel Award in basic biomedical science, the Gairdner International Award, the Amgen Award of the Protein Society, the Albert Lasker Award in Basic Medical Research, the Louisa Gross Horwitz Prize of Columbia University and the Dickson Prize in Medicine from the University of Pittsburgh. He was awarded the Nobel Prize in Medicine in 2013. He has been awarded honorary doctorate degrees from the University of Geneva and the University of Regensburg. He is a member of the National Academy of Sciences and the American Academy of Arts and Sciences. In 1999, he was elected President of the American Society for Cell Biology and was appointed Editor of the Annual Review of Cell and Developmental Biology. In 2002, he was elected Chair of the Biochemistry Section of the National Academy of Sciences and was selected as Scientific Director of the Jane Coffin Childs Memorial Fund for Biomedical Research. In 2005, he was elected Chair of the Biology Class of the NAS and in 2006 he was appointed Editor-in Chief of the Proceedings of the NAS. At UC Berkeley, Schekman has assumed a number of leadership positions in Departmental and campus affairs. In addition to serving a five-year term as Biochemistry Division Head, Schekman served as Chair of the Department of Molecular and Cell Biology. Currently, he serves as Chair of the Chancellor's Advisory Council on Biology, a virtual College of Biology that represents all 250 life science faculty distributed within the College of Letters and Science, School of Public Health, School of Optometry, School of Engineering, College of Chemistry, and College of Natural Resources. In 2004, he organized a campus-wide stem cell biology center to capitalize on California's investment in the application of human embryonic stem cells to regenerative medicine. Randy Wayne Schekman was elected a member of the American Philosophical Society in 2008.

Irving Weissman is Professor of Pathology, Professor of Developmental Biology, and Director of the Institute of Stem Cell Biology and Regenerative Medicine at the Stanford University School of Medicine. A major contributor to cellular immunology, virology and oncology, he clarified the thymus's role in producing T-lymphocytes; implicated viral receptors in leukomogenesis; discovered lymphocyte homing receptors for lymph node venules; and characterized cellular recognition in protochordates. Weissman was the first to isolate mammalian stem cells, identifying these blood forming cells in mice and humans and defining the stages of development between stem cells and mature blood cells and cells of the immune system. This has led to important new treatments for leukemia and lymphoma since the stem cells he isolated are the ones that allow successful human bone marrow transplantation. Another important contribution by Weissman and his colleagues was the development of the SCID-hu mouse, which has functional human immune cells. This model allows human disease to be studied in vivo in experimental rodents. Weismann's transplantation of human tissue and cells to an immunodeficient mouse model has allowed him to isolate human hematopoietic stem cells. Most recently, he has isolated human stem cells capable of generating brain neurons. Irving Weissman received his Ph.D. from Stanford in 1965 and has served on the university's faculty since 1969. He is a member of the National Academy of Sciences (1989) and the American Academy of Arts & Sciences (1990) and a fellow of the American Association for the Advancement of Science (2009). He has been awarded the Linus Pauling Medal for Outstanding Contributions to Science; the Jessie Stevenson Kovalenko Medal of the National Academy of Sciences; the E. Donnall Thomas Prize of the American Society of Hematology; and the Robert Koch Award. Irving Weissman was elected a member of the American Philosophical Society in 2008.
