He first became interested in CSCW in 1988, when it became the focus of his post-doctoral work at the Alberta Research Council. Since then, he and his GroupLab team have published many papers in HCI and CSCW. Their novel software includes GroupKit (a groupware toolkit), the soon to be renamed TeamRooms (a groupware delivery platform designed around a room-based metaphor), and prototype systems that illustrate how awareness of other's activities can be supported over distance. He is also the author and editor of four books, two concentrating on CSCW: Computer Supported Cooperative Work and Groupware (Academic Press, 1992), and Groupware for Real Time Drawing (McGraw Hill Europe, 1995).
