**Research**

In simplest terms, I'm a logician, working in computer science, mathematics and philosophy. In my research I'm particularly interested in modular and uniform approaches to the mathematical theory of logics that are designed for a wide array of reasoning tasks. I'm based at UCL in the Programming Principles, Logic and Verification group, where I am a research fellow and co-investigator on the EPSRC funded 4 year project A coalgebraic framework for reductive logic and proof-search (ReLiC), working with Prof. David Pym and Prof. Alexandra Silva. At the moment I’m working on:

A coalgebraic theory of proof-search and goal-directed reasoning;

Applications of many-valued logics to concurrency and consensus;

Cyclic proof theory for non-classical logics;

Mathematical foundations and metatheory for variants of bunched and separation logics.

Issues in the philosophy of logic, including proof-theoretic semantics, abductive reasoning and logical pluralism.

In my PhD at UCL I was supervised by David Pym and formulated modular and uniform mathematical foundations for the family of bunched logics. I obtained my MSc in Logic at the Institute for Logic, Language and Computation in Amsterdam, and my MSci in Mathematics & Philosophy at the University Of Bristol.

I also run the PPLV group’s research seminar. Interested in visiting and giving a talk? Get in touch!
