I am a Georgina Sweet Australian Laureate Fellow in mathematics and the Chair of Applied Mathematics at the University of Sydney. For more information about me, see the pages on brief history and media.

I appeared in a Q&A episode Time Travel, Teaching and the Meaning of Life with Matt Covell (360), Brian Cox, Richard Gill and Miranda Tapsell. (If you are outside Australia, you can dowload the mp4 file to watch the show.)

My research interests lie in non-linear differential and difference equations, with a particular focus on asymptotics and integrable systems such as the Painleve equations. For (less technical) information see

If you are a prospective student, here is some information for honours students. A recent talk I gave was the one at SUMS(3.1Mb).

Trixie Barretto (who works at the University of Sydney) made a video of me:
