After a postdoc research career in physics, I worked in the games industry from 1999, writing code for 59 game SKUs on 13 platforms (from Gameboy Colour and Playstation through to Xbox360 and Playstation 3) before returning to academia when I joined Manchester Metropolitan University in 2013. Highlights of my game development career include writing the critically acclaimed fluid flow code for Hydrophobia and the physics code for the World Snooker Championship series, and later on, Pool Nation. I teach game development, programming and high-performance computing.
