I am a professor in the School of Informatics and the School of Library and Information Science at Indiana University. I am also an adjunct professor of Cognitive Science. I research and teach in the areas of HCI, CSCW and ubiquitous computing.

My research focuses on augmenting and extending everyday learning and work activities with interactive technologies that move "beyond the desktop". This involves designing enhanced user experiences through appropriating and assembling a diversity of technologies including mobile, wireless, handheld and pervasive computing.
