I work at the University of New South Wales, where I use Ruby to analyze biological data.
In part of my spare time, I work on fun programming projects. One was trying to analyze what underlies Wikipedia's Get to Philosophy game. I also worked on one called the "Small Eigen Collider".
I'm currently learning Japanese, and I'm an active participant in lang-8.com, a website where you write journal entries in a language you're learning, and get corrected by native speakers of that language. In return, you correct people writing entries in your native language. Recently, I've been asking a few questions prompted by slightly incorrect English I've encountered on lang-8.
