Research Interests
My main research interests are in geometric numerical integration, dynamical systems, and integrable systems.
Other current members of the research group in scientific computation and dynamical systems are David McLaren, Will Wright, Peter van der Kamp, Omar Rojas, and Ivanky Saputra.
I am chief investigator of the ARC Centre of Excellence for Mathematics and Statistics of Complex Systems, which has a major node at La Trobe University.
