Dr. Aaron Ciechanover is a Distinguished Research Professor in the Technion–Israel Institute of Technology in Haifa. Following national service as military physician (1973-1976), he continued his studies to obtain a D.Sc., Technion in 1982. There, as a graduate student with Dr. Avram Hershko, they discovered that covalent attachment of ubiquitin to a target protein signals it for degradation. As a post-doctoral fellow with Dr. Harvey Lodish at the Massachusetts Institute of Technology (MIT), he continued his studies on the ubiquitin system and made additional important discoveries. Over the years, it has become clear that ubiquitin-mediated proteolysis plays major roles in numerous cellular processes, and aberrations in the system underlie the pathogenetic mechanisms of many diseases, among them certain malignancies and neurodegenerative disorders. Consequently, the system has become an important platform for drug development. Among the numerous prizes Ciechanover received are the 2000 Albert Lasker Award, 2003 Israel Prize and the 2004 Nobel Prize (chemistry, shared with Drs. Hershko and Rose). Among many academies, Dr. Ciechanover is member of the Israeli National Academy of Sciences and Humanities, American Academy of Arts and Sciences (Foreign Fellow), American Philosophical Society, U.S. National Academy of Sciences and the Institute of Medicine of the U.S. National Academies (Foreign Associate), and the Russian Academy of Sciences (Foreign Member). He received his M.Sc. and M.D. from Hebrew University in Jerusalem.
Adrian is a board-certified physician scientist with more than 20 years of research and clinical development experience spanning oncology, infectious disease and neuroscience. He received his medical degree and Ph.D. from the University of Leeds, following scientific training in the laboratories at Genentech. Thereafter he completed his residency and fellowship through joint academic and clinical training at the John Radcliffe Hospital and University of Oxford, before joining the faculty of the Nuffield Department of Clinical Laboratory Sciences. He has devoted his career to building and leading high performing teams to accelerate clinical development for small and large molecule therapeutics in industry. Adrian has contributed to the development of approved products including Avastin®, Zemdri®, Tarceva®, Zelboraf®, and Cotellic®, and investigational medicines including MetMAb, Apo2L, anti-DR5, anti-LRRK2, anti-LILRB4, anti-CD96, anti-CD200R1, and anti-PPARG and has authored over 60 peer-reviewed papers.
Dr. Brenda Schulman is Director of the Department of Molecular Machines and Signaling at Max Planck Institute of Biochemistry, Honorary Professor at Technical University of Munich and adjunct faculty at St. Jude Children’s Research Hospital. Dr. Schulman’s research group studies biochemical mechanisms underlying regulation by ubiquitin and autophagy pathways. Her lab has developed methods and tools to probe fleeting intermediates in ubiquitin and ubiquitin-like protein transfer cascades, and implemented them to determine the structural mechanisms of major families of E3 ligases, with a particular focus on dynamic multiprotein complexes including cullin-RING E3 ligases. Dr. Schulman is an elected member of American Academy of Arts and Sciences, the National Academy of Sciences, European Molecular Biology Organization (EMBO), and the German National Academy Leopoldina and has been recognized by awards including most recently the Gottfried Wilhelm Leibniz Prize and Ernst Jung Prize for Medicine. Dr. Schulman received her Ph.D. from Massachusetts Institute of Technology (MIT) studying protein folding with Peter Kim before developing an interest in the regulation of protein degradation during her postdoctoral studies first at Mass General Hospital (MGH) Cancer Center with Dr. Ed Harlow, and then at Memorial Sloan-Kettering Cancer Center with Nikola Pavletich.
Dr. Kevan Shokat is an Investigator of the Howard Hughes Medical Institute, Professor in the Department of Cellular and Molecular Pharmacology at the University of California, San Francisco and Professor in the Department of Chemistry at the University of California, Berkeley. Dr. Shokat’s research group is focused on the discovery of new small molecule tools and drug candidates targeting protein/lipid kinases, GTPases and RNA helicases. His laboratory utilizes the tools of synthetic organic chemistry, protein engineering, structural biology, biochemistry and cell biology. He was inducted into the National Academy of Sciences (2010), the National Academy of Medicine (2011) and the American Academy of Arts and Sciences (2011). He has commercialized discoveries from his laboratory through co-founding several biotechnology companies, including Intellikine, Araxes, Wellspring Biosciences, Kura Oncology, eFFECTOR Therapeutics, Mitokinin, Revolution Medicines and Kumquat Biosciences. He received his B.A. in chemistry from Reed College and Ph.D. in organic chemistry at University of California, Berkeley with Professor Peter Schultz, and he carried out post-doctoral work in cellular immunology at Stanford University with Professor Chris Goodnow.
