My research is focused on understanding the transmission of infectious diseases of both humans and animals, with the aim of developing better predictive models for informing infection control strategies and policies.
A substantial part of this interest lies in understanding the structure of human social networks, and in identifying risk factors for transmission. To this end I am at the leading edge of developing new quantification methods and characterising human social networks, and developing realistic network models of contagious processes.
I am also interested in the evolutionary dynamics of infectious diseases, the sociological and ecological processes that drive evolution, and the implications for control and mitigation.
My research includes the epidemiology of pneumococcal infection, rotavirus, norovirus, Ebola, seasonal and pandemic influenza, and other respiratory viruses.
