Research Interests

• Human-Computer Interaction
• Information Visualisation
• Visual Analytics
• Web-based Technology
• Mobile Phone and other Small, Smart Assistant User Interfaces

Practical Application, currently focusing on visual, ontology-guided analytics, in two main areas:

• Knowledge Management - both personal knowledge and links out to local communities of interest and the wider, global information space
• the Linked Open Data Initiative
• Microposts – the merits of the tiny chunk mode of information exchange and the particular challenges this form of communication poses
