Dr Cheung obtained his Ph.D. in 1993 from the University of Melbourne. His postdoctoral studies were undertaken at Monash University. He began his teaching career (2001-2007) at the National University of Singapore. On his return to Australia he joined the Menzies Research Institute as a Principal Research Fellow, and then joined Deakin University in 2011 (June) as an academic teaching staff. He has published over 80 peer-reviewed articles and achieved >2400 total career citations with h-index of 27. His research is currently supported by NH&MRC. Dr Cheung’s research interests centre on the brain injury mechanisms and the identification of novel genes involved in acute and chronic neurodegeneration. Neurodegenerative conditions of the central nervous system continue to have a tremendous impact on Australian society. Excitotoxic neuronal injury is well documented to be a disease mechanism contributing to the pathobiology of stroke (hypoxic-ischaemic injury), traumatic brain injury, Alzheimer's and motoneurone diseases. Excitotoxic neuronal injury occurs because the extracellular concentration of L-glutamate reaches toxic levels and there is overactivation of ionotropic glutamate receptors. This subsequently leads to inflammatory responses, oxidative damage and eventual neuronal death. Since 2003 his research group has continued to use microarray and proteomics to search for molecular markers and cellular signalling pathways that may be useful diagnostically or therapeutically in neurodegenerative diseases. Currently his group is investigating the role of cell cycle-associated protein kinase in excitotoxic neuronal death. Targeted gene delivery into primary cerebral cortical neurons using lentiviral vector mediated overexpression and knockdown functional studies is employed in his research study.
