Alistair Sutcliffe is Professor of Systems Engineering in the Manchester Business School, University of Manchester. He has been principal investigator on fifteen EPSRC and European Union projects on requirements engineering, multimedia user interfaces, safety critical systems and cognitive modelling for information retrieval. Currently funded research projects include EPSRC/ESRC Developing Theory for Evolving Socio-technical Systems (TESS), which is investigating technology-mediated social and work relationships based on Dunbars Social Brain Theory; EPSRC e-Science project ADaptive VISualisation tools for E-Science collaboration (ADVISES), which is producing interactive visualization tools for health informatics researchers; and EPSRC Artificial Cultures, which is researching evolutionary computing simulations for complex socio-technical systems. His research interests span a wide area within human computer interaction and software engineering. In HCI particular interests are interaction theory, and user interface design methods for the web, multimedia, and safety-critical systems; application of cognitive theory to design, and design of complex socio-technical systems. In software engineering, he specializes in requirements engineering methods and tools, scenario-based design, knowledge reuse and theories of domain knowledge. Alistair Sutcliffe is a leading member of both the international HCI and requirements engineering communities. He serves on the editorial boards of ACM-TOCHI, REJ and JASE. He is founder of IFIP TC-13 Working Group 13.2 Methodology for User-Centred Design and a member of IFIP working groups 8.1 (Information Systems) and 2.9 (Requirements Engineering) and is the editor of the ISO standard 14915, on Multimedia user interface design. He has over 200 publications, including five books, and several edited volumes of papers. He was awarded the IFIP Silver Core in 2000.
