Research Interests

Much of my work is in the area of operator theory and the geometry of Banach spaces. In particular my work has concentrated on the relationships between functional calculus and integral representations for operators, and how this is affected by geometric properties of the spaces on which the operators act. More recently I have been investigating geometric properties of metric spaces.

Short Biography

Born and bred in Perth, Western Australia, I completed a BSc(Hons) in Pure Mathematics in 1982. After 2 years working as a mathematician and programmer for a surveying company I returned to study in 1984. I completed an MSc at the University of Toronto under the supervision of Peter Rosenthal in 1985 before going to Edinburgh to start a PhD with Alastair Gillespie. My PhD was awarded in 1988 for a thesis entitled "Well-bounded operators and the geometry of Banach spaces".

On completing my PhD I returned to Australia to a postdoctoral position at Macquarie University working with Alan McIntosh. In 1989 I was lured to the other side of Sydney to take up a lectureship at UNSW.

I retired in 2023, but am still active in the school.


Many of my publications are available on-line.
