Pedro Henrique Azevedo de Amorim

I am a Research Associate at the department of Computer Science of the University of Oxford where I work with Sam Staton. Prior to that I completed my PhD at the Computer Science Department at Cornell University working with Dexter Kozen.

My research interests lie mainly in formal verification, programming language theory, and their intersection. In particular I'm interested in applications of Category Theory, Type Theory, Proof Assistants and Logic to programming languages.

Recently I've been interested in the semantics of probabilistic programming languages and applications of substructural logics to programming languages.
