David Smith

David joined the University of Oxford as a senior researcher in February 2023.

David's research focuses on developing infectious disease models to assess the impacts and efficiency of public health interventions. He is particularly interested in embedding transmission models within health-economic evaluation frameworks to inform intervention design in low- and middle-income settings. His ongoing research includes projects (1) assessing the health-economic benefits of vaccination campaigns against emerging infectious diseases like Lassa fever and chikungunya, (2) optimising population-based SARS-CoV-2 surveillance programmes, and (3) estimating the health and economic impacts of global antibiotic use policy decisions. 

Prior to joining Oxford, David was based at Institut Pasteur in France, where he used transmission modelling to study various topics in nosocomial infection control. Previously, David worked as a mathematical modeller at Public Health England, and was involved in projects including national evaluations of inappropriate antibiotic prescribing and healthcare-associated infection.

David holds a PhD in public health and biostatistics from Université Paris-Saclay and an MSc in ecology and evolutionary biology from the University of Toronto
