I am a senior researcher in statistical genetics and pathogen dynamics at the Oxford Big Data Institute working on the BEEHIVE project which is a cross-European study of HIV genomics and virulence. I am particularly interested in developing tree-based methods for answering statistical questions about HIV genotypic variation within and between patients.
Previously I was a postdoc in the biomathematics group at Imperial College London. I used mathematical ideas from combinatorics, topology and statistics to explore the complicated world of evolutionary trees. Caroline Colijn and I developed a method for comparing phylogenetic trees to reveal distinct evolutionary patterns present in data, which is available in the R package treespace.
On this site you can find more information about my publications and software. There is also a blog where I attempt to provide easy-to-read descriptions of my research. You can find me elsewhere on the web at:
