Aaron Ciechanover, M.D., D.SC

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.

David Komander, Ph.D.

Dr. David Komander is Head of the Ubiquitin Signaling Division at the Walter and Eliza Hall Institute of Medical Research (WEHI) in Melbourne, Australia. He worked as a Beit Memorial Fellow at the Institute of Cancer Research in London, before starting a prolific lab at the MRC Laboratory of Molecular Biology, Cambridge UK (2008-18). The Komander lab has developed various methods to interrogate the complexity in the ubiquitin code and uncovered the molecular basis for specificity in the ubiquitin system in E3 ligases, ubiquitin binding domains and deubiquitinases (DUBs), discovering unappreciated linkage preferences in OTU DUBs, new human enzymes including OTULIN and establishing DUBs as drug targets. In the last few years, his lab has structurally characterized all key components mediating the ubiquitin-dependent degradation of mitochondria via PINK1/Parkin-mediated mitophagy, providing the molecular underpinning of early-onset parkinsonism. At WEHI, David now also has access to state-of-the-art facilities to interrogate ubiquitin enzymes at the physiological level, and to develop small molecule probes and inhibitors to enable drug discovery. David is a member of the European Molecular Biology Organization (EMBO), and a Lister Fellow. He received his Ph.D. from the University of Dundee.
