I am currently a Lecturer in the School of Computer Science at the University of Wales at Bangor. My work involves research into Artificial Intelligence and Intelligent Agents. Ongoing research has also specifically focused on applying text compression-based language models to Information Retrieval(IR) and text mining (i.e. Information Extraction). Before I came to Bangor, I was a research fellow with the Information Retrieval Group under Prof. David Harper at The Robert Gordon University in Aberdeen, Scotland from 1999-2000; an invited researcher in the Information Theory Dept. at Lund University in Sweden in 1999; and a Research Assistant in the Machine Learning and Digital Libraries Labs at the University of Waikato in New Zealand in 1998. At Waikato, I completed my Ph.D. in 1998 on applying text compression models to the problem of modelling English text.
