Ruth is Professor of Computer Sciences in the School of Maths and Computer Science at Heriot-Watt University. She researches intelligent graphical characters, affective agent models, human-robot interaction, and interactive narrative. She was a founder of the International Conference Intelligent Virtual Agents. She has more than 200 publications - book chapters, journals, and refereed conferences. After a first degree in mathematical economics at the London School of Economics Ruth entered computing with ICL as a graduate trainee in 1976. After three years of technical support she moved to Sheffield University where she worked in the micro-computing laboratory and developed an interest in Artificial Intelligence. During five years as a lecturer at the Sheffield Hallam University she developed these interests with particular reference to cognitive modelling, natural language and intelligent interfaces. In 1989 she took up a post at the Artificial Intelligence Applications Institute in Edinburgh University where she specialised in knowledge acquisition and knowledge engineering methodologies, working in the South Bridge building destroyed by fire Dec 7th 2002. This was followed by two years as leader of the AI group at the National Advanced Robotics Research Centre on the University of Salford campus with special responsibility for task planning. The robotics work done there was continued by UK Robotics, more recently known as RTS Advanced Robotics Moving to the then IT Institute in Salford University in 1992, she worked on co-operating robots with Dave Barnes, then at Salford and now at Aberwstwyth, linking a task planner to a behavioural robot architecture. In 1998 she moved to the newly set up Centre for Virtual Environments and located her research in the overlap between 3D interactive graphics and artificial intelligence, first as Senior Lecturer, and then, from 2000, as Professor of Intelligent Virtual Environments. She moved to Heriot-Watt University in 2004.
