I was Head of the Department of Mathematics at the Australian National University from 2006-2012.
I am heavily involved in the computational science community in Australia. From 2003-2006 I was the national coordinator of the Australian Partnership for Advanced Computing (APAC) Education, Outreach and Training program. I am currently the treasurer of the Computational Mathematics Group, a special interest group of ANZIAM.
My research area is the application of efficient and robust numerical methods for the solution of partial differential equations.
I am the lead developer at the ANU of the ANUGA hydrodynamic flooding and tsunami modeling software. ANUGA is an open source computational tool that models the impact of dam breaks, floods and tsunamis on communities. It is used extensively by councils, governments and consultant engineers. You can try running the code via our online clinic.
In the area of data fitting I have developed sparse grid methods for Multidimensional function fitting and approximation of high dimensional probability density functions. I also developed a finite element approximation method for thin plate spline functional smoothing which can scale to millions of data points.
In 1980, I completed my MSc at Flinders University, supervised by Prof Garth Gaudry, working on \(A_p\) spaces and asymmetry of \(L_p\) operator norms for convolution operators. In 1985, I completed my PhD at the University of California, Berkeley, supervised by Prof Alexandre Chorin, working on the Convergence of a random walk method for the Burgers equation.
