My interests in mathematics are motivated by problems in the natural world--but recently, I've become intensely interested in mathematical ideas arising from quantum computing.
I am a Payne-Scott Professor of Mathematics and the Chair of Applied Mathematics at the University of Sydney. I use mathematical ideas and tools from all areas, including algebra, geometry, analysis and mathematical physics. For more information about me, see the pages on brief history and media. I can also be found on Mastodon and Bluesky.
