Following the completion of his PhD in 2002, Dr Matthew McKenzie undertook his postdoctoral research in the laboratory of Professor Michael Duchen, University College London. There he investigated how mitochondrial membrane potential, calcium handling and ATP generation are disrupted in mitochondrial disorders using state-of-the-art confocal imaging techniques.
In 2004, Dr McKenzie returned to Australia to work in Professor Michael Ryan’s laboratory at Melbourne’s La Trobe University. During this time, he received an NHMRC Peter Doherty Fellowship, and subsequently an NHMRC Career Development Fellowship, to study the biogenesis of mitochondrial complex I and how inherited defects can disrupt this process.
In April 2011, Hudson Institute of Medical Research recruited Dr McKenzie as a Research Group Leader in the Centre for Genetic Diseases. His current research focuses on interactions between protein complexes involved in mitochondrial fatty acid beta-oxidation (FAO) and oxidative phosphorylation (OXPHOS), and their importance in human disease pathology. The Australian Research Council recently recognised Dr McKenzie’s research excellence with a prestigious Future Fellowship. Additionally, he also receives support from the Australian Mitochondrial Disease Foundation, the William Buckland Foundation, Marshall Edwards Inc., USA, and Monash University.
