I am a professor in the Mathematics Institute and the School of Life Sciences.
My interests span epidemiology, ecology and evolution. I focus on the roles of spatial interactions and stochasticity (randomness), and how these can affect the dynamics, control and persistence of biological organisms.
More specifically, I have recently studied a range of applied epidemic problems, from the optimal vaccination of individuals during a pandemic influenza outbreak to the prediction and control of foot-and-mouth disease in Britain and the USA. I am particularly interested in the development of new models and techniques that will provide greater insights into population dynamics. Much of this new methodology centers around "pair-wise" approximation models for network-based processes, or moment-closure methods for stochastic processes.
