# David Howden

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.

### Research Interests

- Group Theory
- Computational Group Theory

### TextMate Bundles

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

### Software (old)

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.

### Fun stuff!

- 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.
