Research

I am interested in all aspects of programming language semantics, be they operational or denotational (or somewhere between the two). My research makes use of techniques from mathematical logic, type theory and category theory to advance the foundations of programming language semantics. The aim is to develop mathematical models and methods which aid language design and the development of formal logics for specifying and reasoning about programs, with an emphasis on higher order, typed programming languages, such as ML and Haskell. I have a long-standing interest in the semantics and logic of names, locality and binding.

NominalSetsBook
  • Nominal Sets provide a promising new mathematical analysis of names in formal languages that is based upon symmetry. They have many applications to the syntax and semantics of programming language constructs that involve binding, or localising names and to logics that underly systems for machine-assisted reasoning about programming language semantics.
