I am a Senior Group Leader in Pathogen Dynamics at the Big Data Institute, and Professor in the Nuffield Department of Medicine. I am interested in studying the population dynamics and epidemiology of pathogens, and translating this knowledge to public health. The primary tools used in my group are mathematical modelling and pathogen genomics.

Trained in theoretical particle physics, I converted to mathematical biology after my PhD in 1998. I was Royal Society URF and then Professor in the Department of Infectious Disease Epidemiology at Imperial College before joining the BDI at Oxford in 2016.
