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.
I am the Director of Postgraduate Studies - Research in the School of Mathematics and Statistics.

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
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.
Since arriving at UNSW, I have got married to
been promoted, and have passed my eyes across more first year papers
than I care to remember! Our family is now up to 6 with the arrivals of
Joshua (1997), Matthew (2000), Shane (2003) and
(2007...spoiling the arithmetic progression).
Many of my publications are available on-line.
