A Brief Biographyof David Evans
David Evans was born in Sydney in 1961 and his family then
moved to upstate New York, then Cambridge, England, then Griffith
in NSW. When he was 11, in 1972, his parents became political
staffers, so he moved to Canberra.
He attended the University of Sydney for five years from 1979
where he did science and engineering, and then spent a further
five years at Stanford University at Palo Alto in California,
doing a PhD in electrical engineering. Of that period as a post-graduate
student in one of the most prestigious universities in the world
I did a controversial thesis, which altered and extended some
basic bits of the maths used in electrical engineering. The older
professors strongly encouraged me, but many of the younger ones
reacted very strongly and negatively against it, perhaps because
it undermined their knowledge and thus their status. So much
for science gracefully accepting and using better ideas as they
After taking out his doctorate he worked for a year in Silicon
Valley and then returned to Australia to write a book on the
research he had done for his PhD. He had planned to spend a year
or two writing, but during his writing he discovered "lots
more interesting stuff and mainly did my own research until 1999".
In the meantime, to support himself, he traded on the stock market
and did some programming odd jobs.
In 1999, he got married but then crashed on the stock market
and had to get a job. He started working as a consultant for
the Australian Greenhouse Office where he wrote the software
which the Australian Government uses to calculate its land-use
carbon accounts for the Kyoto Protocol. Entitled FullCAM,
the software models forests and agricultural systems and their
exchanges of carbon with the atmosphere. It models individual
plots, estates of plots, and spatial arrays of plots connected
to spatial information such as rainfall, temperature, soil type,
farming practices, and satellite images of clearing and revegetation.
At the same time he went back to the stock
market and recovered from his crash of 1999. In 2006 he was able
to leave the AGO to return to his own projects, which includes
writing Geometric Fourier Analysis, a book with original
mathematics that introduces a geometrical approach to Fourier
analysis, improved methods in several areas of classical mathematics,
and faster algorithms. He is also writing a word processor software
package that handles equations, tables, and long documents properly
