Below are selected publications and recent-ish talks for download by me and, with their permission, by my amazing students and collaborators. Where a paper isn’t available open access I’ve uploaded preprints where possible, but note that these are not the final published article, and are subject to minor changes. If you have any questions, drop me a line! I love a good natter about research.
