About me

Me I am a mathematician who enjoys working with ideas from computer science. My main interest is in computational topology, which basically means I get to play with geometry on supercomputers. One of my larger projects is working on the topological software Regina.

I am currently Associate Professor and a QEII Research Fellow in the School of Mathematics and Physics at the University of Queensland, Brisbane, Australia. I have previously worked in the mathematics departments at RMIT University, the University of Melbourne and Oklahoma State University, as well as a three-year stint in the finance industry.

I am a great fan of enrichment programmes for high school students, and I have a long involvement with the Informatics Olympiad, the Mathematics Olympiad and the National Mathematics Summer School. See below for details.

Research, publications and grants

Trivial and non-trivial loops on surfaces My main research interest is geometry and topology, with a focus on spaces in three and four dimensions. I typically approach this field from the perspective of combinatorics, algorithms and computation.

We run a weekly informal computational geometry & topology / discrete algorithms meeting, where staff and/or students talk for an hour about their research, or a paper, or just something that others might like to learn about. See the schedule of speakers, and of course feel free to come along if something tickles your fancy.

My other research interests include algorithm design, cryptography and information security, combinatorics, and the development of programming competitions. I publish in all of the areas listed above; see my separate list of publications for details.

I am currently working on a variety of projects from different funding sources, including two ARC Discovery Projects (one with a QEII Fellowship). See my separate list of grants for details.

PhD and honours supervision

If you are interested in talking about honours projects, summer research projects or possible areas for a PhD, send me an email and I'll be happy to meet up for a chat.

Research topics would draw on the fields of geometry, topology, combinatorics, algorithmics and/or operations research, and would typically involve the interplay between several of these areas. Some examples:

This list is by no means exhaustive, and you are of course welcome to bring along your own ideas.

Informatics and mathematics olympiads

IOI logo The International Olympiad in Informatics (IOI) is the premier competition worldwide for high school students in computer programming and algorithm design, with teams from 80–90 countries competing each year.

I have been involved in the Australian programme since its inception in 1998, acting as Director of Training (1999–2008), Team Leader (2001–2008) and Deputy Leader (1999–2000). I am currently a member of the International Scientific Committee (2009–2014), which oversees the scientific content and development of the IOI.

We have recently kicked off the Queensland Informatics & Programming club (QIP), a Brisbane-based forerunner to the national Informatics Olympiad programme. This is a great place for interested high school students to meet like-minded people, do some programming and learn about algorithms. See the QIP site for details!

Some big news from last year: IOI 2013 was held in Australia! The event was hosted at the University of Queensland in partnership with the Australian Mathematics Trust, and by now many of the organisers may have even recovered. We hope you all had fun!

Before my time with the IOI, I was involved with the Australian Mathematical Olympiad Programme. I also continue to teach courses in surfaces and knot theory at the National Mathematics Summer School.

Software

Regina logo I am a great believer in open-source software, and I have spent much time working with open-source projects over the years. Some projects I am currently involved in:
