About DM

What I Do

I studied astrophysics at the University of Sydney. My Ph.D. project was a study of absorption lines in high-redshift quasar spectra, using high-resolution spectroscopy observations made at the 3.9 metre Anglo-Australian Telescope at Siding Springs, near Coonabarabran, New South Wales.
I taught experimental physics in the university undergraduate laboratories for seven years.
I gave lectures on stellar evolution and cosmology as part of an adult education course in modern physics for three years.
For two years I was the Webmaster and Australian National Representative for CricInfo, helping to build it from an amateur site to the most popular single-sport web site in the world.
I worked at the Australia Telescope National Facility designing and implementing a WWW preprint server, in cooperation with the Space Telescope Science Institute in Baltimore, USA.
Then I worked with Agentis International, designing and implementing user interfaces and communication protocols to a back end artificial intelligence system.
Then I worked with IBM Global Services Australia, doing web site coding and back end integration for e-business clients.
Then I taught high school science.
Then I worked as an educational consultant for the Australian Institute of Mathematics.
I write books and other material for the GURPS role-playing game line, as well as articles for Pyramid magazine.
I work for Canon Information Systems Research Australia on image processing projects.

If you've found this page looking for the Xvoigt astronomical absorption line fitting program I wrote: It is badly out of date and there are better programs available these days. Try vpguess.
