I joined the School in June 2014 and conduct vaccine epidemiology research at my base overseas, the KEMRI-Wellcome Trust Research Programme, Kenya. My background is one of clinical training in Paediatrics leading to award of a Fellowship of the West Africa Collge of Physicians in Paediatrics in 2005, as well as in epidemiology- obtained a MSc from the School in 2009 and a PhD from the University of Amsterdam in 2012.

Prior to joining the School, I worked as a Clinical Epidemiologist at the Medical Research Council Unit-The Gambia. My research interests and work at the MRCG were in TB Epidemiology.

Antimicrobial Resistance Centre


I am a Distance Learning tutor for Basic Statistics with Computing (EPM101) and Study Design: Writing a grant (EPM201) modules of the MSc Epidemiology and I organise and teach on the Vaccines session on the DTMH course at the school. In addition, I teach on the Postgraduate Diploma in Research Methods course at the KEMRI-Wellcome Trust Research Programme/Pwani University, Kilifi, in Kenya


My research interests are infectious diseases epidemiology specifically vaccine impact studies including assessments of indirect and non-specific effects of vaccines; assessments of crude and effective vaccine coverage, serological surveys of population immunity and innovative approaches to increasing vaccine coverage.

I am a co-principal investigator and co-investigator respectively on the following vaccine effectiveness studies in Kenya-Pneumococcal Conjugate Vaccine Impact Study (PCVIS) and the Rotavirus Immunisation Programme Evaluation in Kenya (RIPEK)

However, I still retain interest in TB Epidemiology- improving TB case finding in populations and understanding risk of disease and interactions with non communicable diseases like Type 2 diabetes.
