I am a professor of Human-Computer Interaction in the Computing Department at the Open University and direct the Pervasive Interaction Lab. I am also a visiting professor of Informatics at Indiana University (where I was from 2003-2006). From 1992-2003 I was at the former School of Cognitive and Computing Sciences at Sussex University. I have also spent sabbaticals at Apple, Stanford University, University California San Diego, and the University of Queensland.

I research and teach in the areas of HCI, ubiquitous computing and CSCW. A particular focus is augmenting and extending everyday learning and work activities with novel technologies. This involves designing enhanced and engaging user experiences through using a diversity of technologies, including mobile, wireless, handheld and pervasive computing.
