**Research.** Publications listing

While my research training is in pure mathematics, my research program has evolved to centre on problems motivated by
biology. This evolution started with problems in the epidemiology of tuberculosis, thanks to the patience of my long-term biologist collaborator, Mark Tanaka. It then evolved a branch looking at the structure of bacterial genomes. This education in interesting biological problems led me to ways to involve the algebra that I had grown up with, using finite reflection groups (and perhaps even related diagram algebras) to model certain evolutionary processes. I was awarded an ARC Future Fellowship to develop these ideas, and have a 2014 paper describing a family of such problems and applications in algebraic biology, that can be found here (or on the arxiv).
Some of the applications of the use of group theory in geneome rearrangements are to problems in phylogenetics, and recently my work has branched into various problems in that area, largely related to the use of phylogenetic networks to represent evolutionary histories, and thanks to stimulating conversations with Mike Steel. This is a rich and active area that requires a range of mathematical tools and so is quite dynamic. For instance, graph theory, probability theory, statistics, combinatorial optimization, and others, all find a role.
My research trajectory can be visualised by the phylogenetic network to the right. Note that time travels down the screen, and there is an example of a Broadly, I am interested in solving interesting problems using mathematical ways of thinking. Biology provides a seemingly limitless source of fantastic problems that require a lot of care to formalise and to solve. A natural way to describe the sort of mathematics I now do might be "applied pure mathematics", but no-one dare say that out loud, let alone put it on the internet. Since I don't really believe in the distinction between pure and applied mathematics any more, I'm letting myself off the oxymoronic hook. |
