Stefan does research into digital technologies to support people living with chronic illnesses. He documents the creative, interesting and sometimes messy reality of how people appropriate these technologies into their everyday life, and works to help designers understand how to improve them in the future. He also builds and evaluates experimental healthcare technologies, often working directly with potential users to understand and respond to their needs. He is a member of the Nottingham Institute of Mental Health, and currently works for the University of Nottingham Digital Research Team.
