I focus on investigating infectious disease transmission dynamics and the impact of vaccines by conducting epidemiological studies to collect key empirical evidence about socio-demographic, biological, and immunological factors. By combining statistical analyses of these data with theoretical approaches to address broader questions of public health importance, I aim to establish a strong evidence base for understanding the impact of vaccines and the changing epidemiology of vaccine-preventable diseases.


Areas of particular interest include:


Evaluating changes in population-level immunity following the introduction of meningococcal, pneumococcal, rotavirus and other vaccines in resource-limited settings



Investigating the epidemiology of and risk factors for asymptomatic meningococcal carriage in Africa



Defining the global seasonality of meningococcal disease and exploring seasonal drivers in the African meningitis belt and elsewhere



Understanding age-specific dynamics of pertussis infections worldwide



Assessing vaccination strategies to address the global threat of influenza
