### Don's background

I'm a research scientist at the Defence Science and Technology Organisation in Adelaide, where I specialise in
the mathematics of relativistic time concepts, radar signal processing, orbital prediction, and 3-dimensional
rotation/orientation theory, with its associated 6-degree-of-freedom maths. I'm also a Member of the
Australian Institute of Physics, and the Australasian Society for General Relativity and Gravitation.

I hold a doctorate from the Department of Physics and Mathematical Physics at Adelaide University, with a
thesis in mathematical physics completed in 1996. My PhD work was concerned with quantum statistical
methods, where I used the tool of influence functionals to study decoherence and the growth of entropy in the
early universe, as well as related topics such as thermal radiance of black holes. I worked with and was
supervised by Paul Davies (Adelaide), Bei-Lok Hu (Maryland), and Andrew Matacz (Adelaide and Maryland).

Before that I completed a masters degree in physics with first class honours in the
Physics Department at the University of Auckland in 1991, specialising in applied
accelerator physics. I did the initial exploratory work which eventually lead to the
establishment there of a PIXE facility. PIXE (proton-induced X-ray emission) is used
for trace element analysis using the idea that proton bombardment will cause materials to
emit tell-tale X-rays and gamma rays. For this I was awarded the Seiichi Waki Prize
in 1990 for best Auckland experimental physics masters thesis. I was also awarded
Senior Prizes in Physics (1988) and Mathematics (1987).

Prior to that I completed a bachelors degree majoring in mathematics at Auckland
University in 1988. In the same year I held a vacation scholarship at the Australian
National University in Canberra, contributing to all levels of the nuclear department's
accelerator mass spectrometry programme, analysing soil samples for their chlorine-36
content.

I have a book published by Springer:
Explorations in Mathematical Physics: the Concepts Behind an Elegant Language, a set of
DSTO-published lectures on statistical mechanics, and DSTO-published reports on the mathematics of
rotation/orientation theory, information fusion, and geolocation, all available on the Internet.
