I am a public health specialty registrar currently funded by the Wellcome Trust as a clinical PhD fellow in Global Health at LSHTM. My PhD is based in The Gambia investigating Group A Streptococcal (StrepA) skin and throat carriage and its relationship to disease. I am conducting a longitudinal household cohort study with frequent microbiological sampling to understand the importance of StrepA carriage in sub-Saharan Africa, and how carriage infleunces StrepA disease. I will also use whole genome sequencing of StrepA isolates to gather to serotype strains and identify transmission events in order to build a mathematical model of within and between household StrepA transmission.

I previously worked for 2 years at the MRC Unit The Gambia on a trial looking at intranasal live attenuated influenza vaccine in children, where I gained experience conducting studies in low-resource settings. I developed an interest in StrepA during that time due to noticing a significant burden of StrepA skin disease in children combined with paradoxically low pharyngitis rates, yet a huge amount of morbidity and mortality from rheumatic heart disease (RHD) in The Gambia. From there I conducted a cross-sectional prevalence study of scabies and StrepA skin disease in children in The Gambia showing a high burden of disease and a marked seasonal increase in bacterial skin infections.

I am working with my supervisors Dr Michael Marks at LSHTM, Dr Thushan de Silva at University of Sheffield, and Dr Adam Kucharski at LSHTM. I am also part of the MRC Unit The Gambia Group A Streptococcal Research Group, where I hope to continue my collaborations with other colleagues, and broaden my research interests and experience.
