My principal research interest is the analysis of medical images using mathematical
modeling techniques. I have been working in this area since 1985. My masters and
PhD projects on the analysis of coronary cineangiograms were mentored by Peter Hunter and Bruce Smaill.
During 1991-1993 I was a postdoctoral research fellow under
Leon Axel in the Medical Image Processing
Group at the University of Pennsylvania where I developed a method for reconstructing the 3D motions and deformations of the heart from tagged cardiac
magnetic resonance imaging (MRI).

I relocated back to New Zealand with the help of an HRC Repatriation Fellowship,
and was subsequently appointed Lecturer in Biomedical Imaging
jointly in the Department of Anatomy with Radiology and the Department
of Physiology. Now, I am Technical
Director of the Auckland MR Research Group (AMRG), which performs clinical trials in heart disease and
is actively developing new methods for measuring heart function from MRI. I am Research
Manager of the Center for Advanced MRI (CAMRI), which is a state-of-the-art clinical and research
MRI facility at the University of Auckland.

I am Principal Investigator of the Cardiac Atlas
Project, which aims to establish a worldwide database of cardiac MRI examinations
by pooling data from a number of research studies, thereby creating a probabilistic
atlas of regional heart function. For a detailed example of a single volunteer,
see the AMRG cardiac MRI atlas.
