Personal profile

Research Interests

My main research interests are in quantum computation and quantum foundations.  I investigate what makes quantum theory different to other plausible theories and how these differences can be exploited in the realm of computer science.  Quantum theory is quite difficult to understand, and a large part of my work involves using category theory to get at the important aspects of quantum theory.  Category theory also provides a beautiful graphical language which makes quantum systems easier to understand.  For this reason, I'm also interested in reasoning in graphical languages and inm particular automated reasoning.
