Brief profile

After completing his PhD, Mike received an Alexander von Humboldt Fellowship and worked on mitochondrial protein import in the laboratory of Klaus Pfanner in Freiburg, Germany. In 2000, Mike joined La Trobe where he undertakes research into understanding the assembly of membrane protein complexes in mitochondria and defects in disease which cause energy generation defects. He also studies the machinery that controls mitochondrial dynamics.  His research has been funded by grants from numerous bodies including the Australian Research Council, National Health and Medical Research Council, and the ARC Centre of Excellence for Coherent X-ray Science where he also leads the Biology program. In 2006, Mike received the Roche Medal from the ASBMB. In 2010 Mike was appointed to professor and later Head of Department. Mike also serves on the La Trobe Institute for Molecular Science Advisory Board and Executive.

Research interests
