In the 1980s I received a Bachelor degree, in the 1990s a Masters degree, and in the 2000s I have completed a PhD (all in Computer Science). Between degrees I spent time working commercially, and as a researcher.

My research interests include Information Retrieval, search engines, and Software Engineering. Can we find and extract useful information from the gigabytes that are available? If we can then how can we build efficient systems to do this?

For more information, see my research pages.
