I started my DPhil [PhD] in 2021, funded by the National Institute for Health and Care Research (NIHR) Health Protection Research Unit in Emerging and Zoonotic Infections. Many public health decisions need to be made with imperfect evidence. I am interested in using mathematical models and observational data to generate the most robust public health information possible. I am approaching this through the question of optimal timing of repeat vaccination against covid-19 for healthcare workers.
I joined the Thames Valley public health programme in 2017. When the covid-19 pandemic started in 2020 I moved to split my time between working with the local Public Health England (now UK Health Security Agency) health protection team and helping the research effort via the International Severe Acute Respiratory and emerging Infection Consortium. The early months of the pandemic made clear the importance of reaching valid conclusions from imperfect observational data. After a brief return to a local authority public health team to work on local implementation of rapid testing for covid-19, I started my PhD in the summer of 2021.
