Research Interests

  • Human-Computer Interaction
  • Information Visualisation
  • Visual Analytics
  • Web-based Technology
  • Small, Smart & Mobile devices — User Interface design and development

Practical Application, currently focusing on visual, ontology-guided analytics, in three 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, with a focus on powering usable technology for the ordinary end user
  • Microposts — the merits of the tiny chunk mode of information exchange and the particular challenges this form of communication poses
