I was a full-time programmer and systems administrator in the Department of Computing's Computing Support Group, when my job was to look after people in the Department, and make sure that their computer systems do what they need them to do. In practice, that translated into maintaining and developing our Linux-based machines, and the many different and varied services they provide — and ensuring they keep up to date with the needs of our students, researchers, and staff.
However, as of July 2012, I no-longer work at Imperial; I've since moved to the University of Cambridge's University Computing Service — see my personal pages there.
I was previously a research assistant and PhD student working for Professor John Darlington in the Social Computing Group. (Formerly the Imperial College Internet Centre / London e-Science Centre.) I submitted my PhD thesis on large-scale network authentication systems at the end of 2010, and successfully defended in late February 2011 and was awarded my PhD on July 31st, 2011.
My academic publications, including my PhD thesis, are available from Pubs.
