Hello. I'm an electronic engineer based in Cambridge, UK, primarily involved in wireless DSP. I graduated from the University of York in 2006 with a starred first MEng, but that by no means implies that I know what I'm talking about!

To any York-goers, I was a member of Vanbrugh College.

I've been a guitarist for about 9 years; my main guitar is a cherry Gibson SG Standard.
