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 travelled around the UK during June-July this year to deliver 9 lectures as the special 2015 Hardy Fellow of the London Mathematical Society. Many people asked me for copies of my slides. They are now on my talks page. Other talks are available too: e.g., my recent talk to SUMS "When applied maths collided with algebra"(3.1Mb).

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.

My research interests lie in non-linear differential and difference equations, with a particular focus on integrable systems such as the Painleve equations. For (less technical) information see what is this thing called painleve?, geometry & asymptotics, AM4 integrable systems

If you are a prospective student, here is some information for honours students.
