Brief Biography
I was born and bred in Wellington, New Zealand, receiving undergraduate and
doctoral degrees from Victoria University of
Wellington (VUW). I liked maths at an early age, discovered psychology at
university, and was fortunate to pursue mathematical psychology at the
Psychophysics Laboratory at VUW with John Whitmore. My
Ph.D. was on receiver operating characteristic (ROC) analysis, particularly on
the removal of error due to inconsistent decision making in psychophysical
tasks.
From 2000-2003 I was a postdoctoral researcher with
Chris Plack at
the University of Essex,
working on psychoacoustical estimates of basilar membrane response in the
cochlea.
I returned to New Zealand in 2003, my ongoing project being a review of
ROC-related literature taken from the medical and engineering literature. While
in Britain, I obtained a large(!) number of psychophysics-related references
from libraries in London and Manchester. Back in NZ, I had more time to spend
reading and reviewing the articles and writing up material from my thesis, and I
learned Delphi so I can upgrade my Pascal programs from my thesis.
I am currently back in the U.K. I have just finished working for
Julie Harris
at the
University of St Andrews (after a
brief but enjoyable stint at the University of Newcastle upon Tyne)
on a project on binocular distance perception, quite literally getting people to
go cross-eyed for science. I was back into Frisbee in NZ, but my Achilles tendon
went "ping" just before Christmas 2003 (much better now). Otherwise, for
professional details, see my Curriculum Vitus.
