Professor Norman Wildberger

Back to

Born and raised in Canada, I now enjoy the warmer Australian life-style, but still like to visit my home country. I was educated at Adam Scott High School in Peterboro Ontario, Richmond Hill High School in Richmond Hill Ontario, University of Toronto (BSC 1979) and Yale University (PhD 1984). I taught at Stanford University (1984-1986) and the University of Toronto (1986-1989) before coming to UNSW (University of New South Wales), Sydney, in 1990. My wife Kim and I have a daughter Ali.
