As I'm retired, what follows will become increasingly out of date...

Bio and Contact information at work

I have (moderate, developmental) prosopagnosia, meaning that I am poor at recognising faces. Please don't take offence if I fail to recognise you: I do it to close friends and family too.

Research

My interests include aspects of software engineering and aspects of theoretical computer science. Especially, I am interested in software design: what good design is, how people do it, how and to what extent tools can help. In recent years I have mostly worked on mathematical aspects of model-driven development, especially bidirectional model transformations. My main affiliation is with the Laboratory for Foundations of Computer Science.
  • Past EPSRC-funded research project, joint with Oxford, on A theory of least change for bidirectional transformations.

    Teaching and administration

    In 2025/6 I am on sabbatical, so I have no teaching and administration duties. In particular I am no longer Director of Research.

    In 2024/5 I taught Software Design and Modelling.
