About

I am a Senior Lecturer in the department of Computer and Information Sciences at the University of Strathclyde. I am a member of the department’s Mathematically Structured Programming (MSP) group.

My research is on programming languages. I use mathematical ideas and structure from logic, category theory, type theory, and denotational semantics to study programming languages and the systems they describe.
