My research interests include the evaluation of child and adolescent public health programmes.

My PhD research focused on rotavirus gastroenteritis in England and Wales using surveillance data to understand transmission and to predict the potential impact of rotavirus vaccination.

Subsequently, I have conducted evaluations of the national child rotavirus and pneumococcal vaccination programmes in England and Wales.

I am currently involved in the evaluation of an adolescent sexual and reproductive health programme (Adolescents 360) in Ethiopia, Nigeria and Tanzania. This four-year initiative (2016–2020) has been developed through human-centred design (HCD) and aims to increase voluntary, modern contraceptive use among adolescent girls between the ages of 15 and 19 in developing countries. The A360 external evaluation includes a process evaluation, quasi-experimental outcome evaluation, and a cost-effectiveness study.
