Bill Gaver is Professor of Design and co-leader of the Interaction Research Studio at the University of Northumbria, London. With the Studio, he has developed novel approaches for pursuing design as research over the course of numerous practice-based projects, many of which have been published and exhibited internationally. He came to Design as a lapsed psychologist and cognitive scientist with a background in HCI and Politics and long-standing engagements with Sociology and STS. This has allowed him to make distinctive contributions to a portfolio of work that includes research products, methodologies and conceptual insights for and about practice-based design research, with an emphasis on ambiguity, ludic design, and emergence.
