I'm a postdoc research associate in the Magma Group at the University of Sydney (from July 8th 2012).

Before that, I was a PhD student at The Mathematics Institute, University of Warwick where my supervisor was Derek Holt.

Include language definition (for syntax highlighting) and some basic snippets.

Many of the projects listed here are no longer available on the web, but

CWRED Coxeter Word Reduction
Includes highly optimised algorithm to compute geodesic automata for Coxeter groups. Also implements word reduction for Coxeter groups.
PlanarGraph
Package for creating and manipulating planar graphs. Includes drawing routines using sphere packing (implemented by Sebastian Jörn).
Schreier-Sims Algorithm
Speedy implementation of the basic Schreier-Sims algorithm implemented in C++. Computes the order of permutation groups and tests membership of elements.
FLINT: Fast Library for Number Theory
As an undergrad, I contributed the beginnings of the zmod_poly module (polynomials with coefficients mod p, where p is less than 2^63), including KS multiplication. Also contributed code to compute Bernoulli numbers using zmod_poly.

Proms Guide - unofficial guide to the BBC Proms 2011. Full programme listings, searchable by artists and composers. Full calendar integration and alert reminder notifications.
boxd - fun, simple and incredibly addictive strategy game.
raspicam - Go API for the Raspberry Pi camera module.
