# Alex Kavvos

Lecturer in Programming Languages

Department of Computer Science

University of Bristol

CV | ORCID | GScholar | Bristol Pure

*I am looking to recruit PhD students interested in any of the following themes.*

Research interests:

- programming languages (theory and semantics)
- type theory (in particular modal type theory)
- homotopy type theory
- logic (including modal and categorical logic)
- (higher) category theory
- formal models of computer security
- concurrency and process calculi
