Alex Rice
I am currently a postdoctoral research assistant working with Chris Heunen and Tobias Grosser on the intersection of programming languages, compilation, and quantum computing. I have just submitted my thesis for a PhD at the University of Cambridge under the supervision of Jamie Vicary.

About Me
I am generally interested at the moment in all things related to programming languages and type systems, and tools for working with these. In my PhD, I developed two variants of the type theory Catt, a type theory which models globular weak infinity categories. These variants had added definitional equality allowing them to model semistrict infinity categories. During this I generated an interpreter for these languages, and formalised a substantial portion of their metatheory in Agda.
I also enjoy formalising things in Agda, programming in rust, and am a user of Emacs and the NixOS Linux distribution. My other interests include ice skating/ice hockey and playing cello in orchestras.
Thesis
My thesis “A type-theoretic approach to semistrict higher categories”, was submitted on 18th April 2024 (pdf)
