Dr. Liam O’Connor
4th October 2020


I am Liam O’Connor, a a Lecturer in Programming Languages for Trustworthy Systems for LFCS at the University of Edinburgh School of Informatics. I specialise in programming languages and type systems, verification, formal methods, and concurrency.

In my previous posting at the University of New South Wales I taught several courses ranging from theory of programming languages to concurrency to formal methods. At Edinburgh, I am focusing primarily on research work for the moment, although I am involved in supervisory duties for Informatics 1A on Functional Programming.

I work regularly in and on the Haskell programming language and the Agda proof assistant. Much of my research work involves these languages. I am the Social Media Editor of the Journal of Functional Programming.

Originally part of my doctorate and now as ongoing research work, I designed the Cogent programming language, and I remain a contributor to its associated verification framework and compiler. This project is part of the long-term vision of the Trustworthy Systems team at CSIRO Data61, to reduce the cost and effort required to make formally verified systems. In the past I have also worked with the Trustworthy Systems team on the l4.verified project and tools for the Isabelle theorem prover. I have also been affiliated with the DPH and Accelerate projects as my PhD supervisor was Prof. Gabriele Keller.

This contains my blog as well as a publication list, and other miscellany.
