Viktor Korolchuk obtained his PhD from the Institute of Biochemistry in Kiev, Ukraine. During the postdoctoral training at Bristol and Cambridge Universities, UK, Viktor have been studying intracellular trafficking and signalling pathways using a range of biochemical, cell biological and genetic approaches. His contributions to the field include: isolation and characterisation of protein kinases associated with endocytic clathrin-coated vesicles (Traffic, 2002; J Biol Chem, 2005); studies of the topologically unusual protein tetherin, its trafficking and role in the development and maintenance of cell polarity (Traffic, 2003; J Cell Sci, 2007; J Cell Biol, 2009); the role of Drosophila trafficking proteins in the recycling of synaptic vesicles, in neuronal development and in regulation of signalling pathways (J Cell Biol, 2007; J Cell Sci, 2007); characterisation of several mechanisms of autophagy regulation including those by calcium, reactive oxygen species, reactive nitrogen species and in the context of a glycogen storage disease (Autophagy, 2009; Hum Mol Genet, 2010; Mol Cell, 2011); a mechanism of cross-talk between autophagy and the ubiquitin proteasome system (Mol Cell, 2009); a novel mechanism of coordinated control of both mTOR and autophagy by nutrients (Nat Cell Biol, 2011); identification of autophagy regulators that suppress the toxicity caused by mutant huntingtin.
