Research Contribution:

Dr Du’s research focuses on understanding the molecular mechanisms of intracellular lipid trafficking and investigating how changes in membrane lipid distribution and metabolism contribute to metabolic disorders and cancer. He received a PhD from UNSW in 2007 for studies examining molecular machinery controlling cholesterol homeostasis and cell signalling. After his PhD training, Dr Du continued to investigate molecular functions of lipid transfer proteins, such as Niemann Pick Type C proteins and oxysterol-binding protein-related proteins. He has since developed a keen interest in intracellular lipid trafficking and its role in human diseases. He has gained further extensive experience in genetics, molecular cloning, genome editing, protein purification, lipidomics, advanced fluorescent microscopy, and new model systems such as yeast and mouse. In 2010, Dr Du became a Senior Research Associate. He is currently leading a research team focusing on organellar membrane lipid dynamics mediated by lipid transfer proteins at the School of BABS, UNSW.

Dr Du has a record of continuing publications in high-profile, peer-reviewed journals, including Cell, Nature, Science, Molecular Cell, Nature Communications, Developmental Cell, Cell Reports, Journal of Cell Biology, Journal of Lipid Research, Molecular Biology of the Cell, and Journal of Biological Chemistry. Dr Du serves as a referee for the NHMRC and a reviewer for the International Journal of Cell Biology, PLOS ONE and others. He is also an active member of the ASBMB and Biochemical Society (London).
