Dr Caroline Trotter

Principal Research Associate, Department of Veterinary Medicine

Academic Director Cambridge Africa, Department of Pathology

Honorary Epidemiologist at Public Health England


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 University-wide programme to promote engagement between Cambridge and African researchers. 

Research themes

Infectious Disease Dynamics:

Epidemiology and control of bacterial meningitis and other vaccine-preventable infections

Drugs and Vaccines:

Epidemiology of vaccine preventable infections, mathematical modelling to predict and compare the impact of different immunisation strategies.

Cambridge Parasitic and Neglected Tropical Diseases Network:
Connections in Africa:
  • I have connections in Chad, Ethiopia, Ghana, Mali, Niger, Nigeria and Senegal through the MenAfriCar consortium (
Connections in Europe:

I have connections in Europe through the European Meningococcal Disease Society

Principal Research Associate

Research Interests

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.
