I completed my PhD in infectious disease epidemiology in the Centre for Paediatric Epidemiology and Biostatistics at the UCL Institute of Child Health in 2008. I used data from a rubella serosurvey in newborn babies linked to birth records to determine maternal rubella susceptibility according to country of birth. Following my PhD, I worked as a statistician at the Health Protection Agency (HPA, now UK Health Security Agency). During my time at the HPA I mainly worked on projects relating to influenza surveillance, including estimating influenza vaccine effectiveness, developing mortality monitoring systems, and analysing data from seroincidence studies of pandemic influenza A/H1N1. I rejoined UCL to work with Professor Ruth Gilbert on a UK overview of childhood mortality in  2011.

Research Themes
Research Summary

I am one of the principal investigators in the Child Health Informatics Group, the lead for administrative data analyses for the NIHR Children and Families Policy Research Unit, and deputy lead for the NIHR GOSH Biomedical Research Centre Applied Child Health Informatics Theme.

My primary research interest is in the epidemiology of respiratory infections, including influenza, respiratory syncytial virus, and SARS-CoV-2 in children. I was a co-I on the VirusWatch study, a UK community cohort study of COVID-19, and I lead the England analyses for VERDI, a Horizon Europe funded consortium focusing on the epidemiology of SARS-CoV-2 in pregnant women and children. 

Increasingly, my work is focused on the impact of the physical environment on children's health and development. I am the principal investigator for the MRC-funded Air Pollution, housing and respiratory tract Infections in Children: NatIonal birth Cohort study (PICNIC) study, and for the Kids' Environment and Health Cohort, funded by Administrative Data Research-UK.

Teaching Summary

I teach on the 'Epidemiology for Child Health' and 'Immunisation and Communicable Diseases' modules for the MSc in Paediatrics and Child Health, the Child and Adolescent Public Health module for the BSc in Population Health, and the Global Communicable & Non-Communicable Disease iBSc module. 

I am one of the co-investigators of the RADIANCE project, providing online training in longitudinal data science: https://radiance.org.uk/ 

I supervise several PhD students and MSc student projects.
