I am a Research Fellow at LSHTM and Statistics Lead at the Vaccine Confidence Project™. I hold a PhD in Mathematics from Imperial College, where I was also an EPSRC Prize Fellow.

My research focuses on using (mainly) Bayesian statistical methods to solve problems at the intersection of public health and vaccine confidence and vaccine acceptance. I am particularly interested in novel methods to infer vaccine confidence at national and sub-national levels; estimating and forecasting vaccine coverage rates for COVID-19 vaccines and routine childhood immunisation programmes; and the social and demographic determinants of vaccine confidence and acceptance.

I have worked extensively on large-scale surveys at global, national, and -- more recently -- sub-national scales, where my recent research seeks to understand local heterogeneities in vaccine acceptance, how this is linked to spatial variation in socio-demographic groups and inequalities, and how this impacts local disease burdens.
