"I find the opportunity to earn a living doing something I enjoy doing, a worthy prize."

Currently I am a Postdoctoral Research Fellow at CSIRO Atmospheric Research in Aspendale. My research/training has primarily been focused on the statistical dynamics and behaviour of nonlinear systems. Nonlinear dynamical systems are important from a purely mathematical perspective in that they typically require a broad range of mathematical tools in combination with advanced computation models to be studied. Nonlinear systems manifest in a variety of physical phenomena, for example in my masters research I looked at the theoretical aspects of using lasers to manipulate complex atoms, the study of which has implication for nanotechnology.

My PhD research and current position is in the area of geophysical fluid turbulence. This work tries to develop an understanding of the interaction of the turbulent eddies of the ocean and atmosphere with the topography of the planet. There are many aspects of turbulence that remain poorly understood due to the strong nonlinearity of the underlying equations

In my work this problem is studied in some generality using both computational and theoretical techniques making our results relevant to many physical problems. The study of nonlinear dynamical systems and in particular turbulence is difficult and at times frustrating. It always remains rewarding especially as the advances we make have direct impact on our society in a variety of ways from improved weather and climate prediction to understanding the dynamics of the oceans and even the evolution of the galaxies.

Perhaps the most rewarding part of my time as a student was the time spent discussing ideas with my colleagues, both students and faculty staff. I consider myself very fortunate to now be able to continue the exchange of scientific ideas and learning in my job. I had decided early in my academic study that I wanted to be a mathematical physicist and would consequently need a postgraduate degree. Although an extended period of study is difficult in a financial and personal sense I find the opportunity to earn a living doing something I enjoy a worthy prize.
