I am a Senior Lecturer in the School of Computing at the University of Leeds. My research takes place under the Artificial Intelligence theme within the School.

My main area of expertise is knowledge representation and reasoning for spatial information. My current work has two aspects:

  • Interdisciplinary Connections between qualitative spatial representations and research in the arts, humanities, and social sciences. An informal overview of this is in these slides.

  • Mathematical and Logical Structures for dealing with information that may be vague and uncertain as well as varying over time and dependent on level of detail (often called granularity). This aspect builds on a variety of various fields of research including qualitative spatial reasoning, rough set theory, and mathematical morphology. The research questions here are often motivated by issues from areas which include geographical information science and formal ontology for the semantic web. A particular focus of recent work has been relations on graphs and modal logics which use these structures as accessibility relations. Further details are available in my publications.

I am the Programme Director for Computer Science in the Joint School established at South West Jiatong University, China, in partnership with the Faculty of Engineering at Leeds.

I have been at Leeds since 2001. Previously I was a lecturer in Mathematics and in Computer Science at Keele University. Even earlier I was a research assistant at the University of Strathclyde in Glasgow. I am a graduate of the University of Manchester where I studied Mathematics (BSc) and Computer Science (MSc, PhD). More recently (2010) after part-time study, I gained a BA (1st class) in Fine Art from Leeds College of Art. I have received funding from EPSRC and AHRC for projects on the interface between Art and Science. The experimentation with three-dimensional drawing was in collaboration with Claude Heath and Patricia Cain.
