I've been doing some research. In real life, there is no algebra.
Audrey Horne in David Lynch's Twin Peaks

I am a Senior Lecturer in mathematics at Heriot-Watt University. My main field of research interest is geometric group and semigroup theory, and a full list of my publications is available. Some recent papers are available for inspection right now at my research page.

After hours

There's more to life than mathematics:

• The Trouble and Strife.

• the music of Bardo Pond, Besnard Lakes, Emily Haines, Dawn Landes, Low, Mission of Burma, Tara Jane O'Neil, Viva Voce, Yo La Tengo.
• the films of Hal Hartley
• the (mis)fortunes of Essex County Cricket Club
• the ups and downs of the Seattle Mariners
• Universities are increasingly adopting fashionable practices from business. Find out some of the consequences at dilbert.com
