I work at the intersection between the computational and social sciences, trying to understand IT in its social context. Specifically, my students and I think about applications of pervasive and ubiquitous computing to problems of real societal concern (e.g. health, sustainability, ageing, distributed families, community engagement). We work in multidisciplinary teams, contributing HCI and CSCW knowledge where they're needed. Our approach is loosely design ethnography, interleaving qualitative field work and use-centred innovation.
