2 Sep 2006 A minor update just to remove some of the scripts I had been linking to that suddenly had started popping up nasty advertising on the page. Sorry about that everyone. Also, just to satisfy Ian: I still only have one head, and it still has hair on it.
24 Oct 2005 By popular (?) demand here's a quick update on what I'm doing now: I'm currently working for a city startup (how long can one justify calling it a startup?) called Columba Systems. I'm working with Chris and the office is just accross the road from Tammay and Richard.
Some time ago now, I did a Ph.D. with the Hot-Star Group at University College London. My main research interest is in the field of photospheric abundances in O stars, but my work to date has also included a study of rotational velocities of O and B stars. A CD version of my thesis is available upon request.
