Biography
I am an infectious disease epidemiologist with an interest in vaccine-preventable diseases, particularly bacterial meningitis. I obtained my first degree in Human Sciences from the University of Oxford, followed by an MSc and PhD in Infectious Disease Epidemiology at the London School of Hygiene and Tropical Medicine. I worked at the Health Protection Agency and then the University of Bristol. In 2013 I moved to Cambridge, joining the Disease Dynamics Unit in the Department of Veterinary Medicine. Since October 2018, I have a joint role as the Academic Director of Cambridge-Africa, a programme that supports African researchers and promotes mutually beneficial collaborations and equitable partnerships between Africa and Cambridge.
Research
My research concentrates on understanding the epidemiology of vaccine-preventable diseases and the impact of immunisation. The majority of my work is on meningococcal infection, and I conduct studies in Europe and Africa. I am also involved in research on group B streptococcus, pneumococcus, rotavirus, norovirus, HPV and rabies.
I use a range of methods including analysis of large databases, systematic reviews, prospective clinical/ field studies, health economics, seroprevalence studies and mathematical modelling. I am most interested in applying these methods to research questions of direct relevance for vaccine policy.
