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 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.

In the Fall, I will be a Marie SkÅ‚odowska-Curie Fellow at the Department of Computer Science and Engineering, University of Bologna, working with Prof. Ivan Lanese.

One ought to notice the correlation between the locations of my career, and Mendelssohn's 3rd "Scottish" and 4th "Italian" symphonies. Since Mendelssohn's 5th symphony was about "Reformation", I shudder to think where I might end up next!

Previously, 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.

My papers are listed on arXiv and dblp.
