My research is on braid groups, mapping class groups, and related structures.  Here I have grouped my papers and book chapters roughly according to topics of particular focus, though there is a bit of overlap.  A list of my publications in reverse chronological order can be found on my listing in Enlighten, the University of Glasgow's online repository.
