# Dr James Laird

## Profile

### Research interests

Research interests lie in and around denotational semantics: the interpretation of computer programs and logical proofs as mathematical objects, such as strategies for a game, functions between domains or morphisms in a category. Jim aims to use these representations to describe, constrain and reason about particular computational effects and control and data flow generally.
