Senior Lecturer in Epidemiology
Fellow of Hughes Hall
I am an infectious disease epidemiologist, based in the Disease Dynamics Unit.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 before moving to Cambridge in January 2013. I am an honorary epidemiologist in Public Health England's Immunisation Department.

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, but I am also involved in research on pneumococcus, group B streptococcus, rotavirus and human papillomavirus. 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.
I work with the African Meningococcal Carriage Consortium (MenAfriCar), a global research effort to study how meningococcal meningitis is spread in Africa, and to document the impact of a new meningitis vaccine (MenAfriVac) on reducing transmission.
I also work on collaborative projects with Public Health England, University of Bristol, St Georges University of London, Agence de Medicine Preventive and the World Health Organisation.

I have supervised 4 PhD students to successful completion at the University of Bristol.
I currently supervise one PhD student and one MPhil student in Cambridge.
