As an introduction, I'm a theoretical computer scientist based at the University of Nottingham, and a former industry programmer.

I'm interested in category theory, logic and the foundations of computer science.

I have taken over from Yuri Gurevich as the editor of the Logic in Computer Science column in the Bulletin of the EATCS. He has been doing this for 37 years! Big shoes to fill.

For my first column, I've rendered my invited LICS 2025 talk into dialogue form: bulletin.eatcs.org/index.php/be...

Back to book writing AKA drawing lots of colourful pictures. This time a proof step relating to the codensity monad transformer, using some new notational tricks and a somewhat angular style.

After finding I'd forgotten a lot of useful stuff, I've finally treated myself to @chrisheunen.bsky.social and Jamie Vicary's excellent book. Great to have so much good stuff in one place, even if that isn't my memory!
