I am a social scientist and epidemiologist using mixed-methods research and realist evaluation to evaluate public health interventions in sub-Saharan Africa. I currently work on the Plus Project which assesses the impact, operational feasibility, efficacy, effectiveness, and cost-effectiveness of Perennial Malaria Chemoprevention given to children up to two years of age in Benin, Cameroon, and Cote d'Ivoire. I have previously worked on studies evaluating nutrition, HIV, family planning, and Covid-19 interventions. My publications contribute evidence on HIV prevention, stigma and HIV, acceptability of family planning, control and containment of COVID-19 and systematic review methods.


Department of Disease Control
Faculty of Infectious and Tropical Diseases


I teach and supervise students undertaking the Nutrition for Global Health MSc.


I am particularly interested in using process evaluation methods to understand how interventions work, for whom, and in what circumstances, and in understanding if and how context influences the delivery and uptake of public health interventions using realist evaluation methods.
