I completed my undergraduate medical training at the University of Ilorin, Kwara, Nigeria and received a Fellowship of the West Africa College of Phyiscians in Paediatrics on completion of the residency programme at the Lagos University Teaching Hospital, Idi-Araba, Lagos, Nigeria. In addition, I hold a MSc in Epidemiology from The School and and got a PhD in Epidemiology from the University of Amsterdam, The Netherlands.

I joined the School in June 2014 and work overseas as a Clinical Epidemiologist at the KEMRI-Wellcome Trust Research Programme,Kilifi, Kenya. The overarching aim of my research is to provide evidence for vaccine policy in low and middle income countries especially those in Africa. I am currently working on vaccine effectiveness studies for pneumococcal and rotavirus vaccines. I am exploring the scientific basis for managing pneumococcal vaccine programmes with only pneumococcal carriage data; and investigating vaccine seroepidemiology in Africa including the scientific basis for coverage and population immunity. My other interests include a lifecourse approach to immunisation in Africa and  innovative approaches/surveillance tools for vaccination including measures of coverage, timeliness, and equity. I currently serve on the Kenyan National Immunisation Coordination Committee and the WHO AFRO Regional Immunisation Technical Advisory Group (RITAG).

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

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.
