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.
