I am an infectious disease epidemiologist, with a background in ecology and theoretical biology. My research is focused on improving our understanding of infectious disease transmission and evolution, with the aim of improving epidemic models and informing 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, through fieldwork and secondary data analysis. I am particularly interested in how realistic models of contagious processes need to be to explain and predict incidence patterns and yet also be useful in epidemic emergencies. My research includes the epidemiology of SARS-CoV-2, seasonal and pandemic influenza, RSV, Ebola, pneumococcal infection, rotavirus, norovirus, as well as other respiratory viruses.
