Dr Toni Robertson is Reader in Human Computer Interaction in the Faculty of Information Technology at the University of Technology, Sydney (UTS). Her research has been published widely in the Computer Supported Cooperative Work, Human-Computer Interaction and Participatory Design literature. She is a specialist in the study of work practice as the basis of technology design, and the application of qualitative and participatory research and design methods. Her research is directed to both understanding and designing the interaction between people, technology and work. She is interested in issues surrounding the use of technology in actual work and social settings, including how an understanding of actual work practices can be developed and then used to design information systems that fit well with their situation of use; participative approaches to, and methodologies for, the design of information systems; human-computer interaction, interaction design and usability issues emerging from the development of new information technology; ethical issues in system design and the representation of work; and how different metaphors for human cognition and work can affect the usability and usefulness of technology.
