You might be interested in my recent work on Continuations and Coexponentials. Here is a draft, and slides from HOPE and LFCS, and links to repositories: coexp and agda-coexp.


I am a Marie Skłodowska-Curie Fellow at the Department of Computer Science and Engineering, Alma Mater Studiorum - Università di Bologna, and also affiliated with the INRIA OLAS Team. The project page is at ReGraDe-CS.

Previously, I was a Research Associate to the Head of School Prof. Simon Gay, at the School of Computing Science, University of Glasgow, and affiliated with the FATA section. Before that, I was a Visiting Research Fellow at the Computer Laboratory, University of Cambridge, on a Paul Purdom Fellowship, working with Prof. Marcelo Fiore, and Prof. Neel Krishnaswami. Even before that, I was a PhD student with Prof. Amr Sabry at the Luddy School, Indiana University Bloomington.

I also work with Hannah Earley on vaire.co.


I study mathematical foundations of computation, through an algebraic lens. My research spans programming languages, type theory, category theory, logic, semantics, constructive mathematics, and formalisation.
