I did my PhD in infectious disease epidemiology in the Centre for Paediatric Epidemiology and Biostatistics at the UCL Institute of Child Health. 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). 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.

After leaving the HPA I worked as a research associate in healthcare quality assessment at Imperial College before rejoining UCL in 2011.

Research Summary

I am interested in the use of routinely collected health data (including death certificates, hospital admission records and general practice databases) for public health surveillance and monitoring the quality of care and the effectiveness of health interventions. I have used these data to estimate the effectiveness of influenza vaccines, the mortality burden of influenza and respiratory syncytial virus, and determine the role of chronic conditions in childhood mortality in the UK.

My particular interest is in the epidemiology of respiratory infections in children. In 2013 I was awarded a postdoctoral fellowship from the National Institute for Health Research to determine the burden of severe influenza in children, and examine whether influenza vaccines, antivirals and antibiotics can prevent hospital admissions.

I am based partly at the Institute of Child Health and partly in the Department of Primary Care and Population Health, and I hold an honorary contract at Public Health England.

Teaching Summary

I run short courses on the analysis of Hospital Episode Statistics for the Administrative Data Research Centre (England) together with colleagues from UCL, the University of Southampton, and London School of Hygiene and Tropical Medicine. I am also an instructor in critical appraisal and statistics on the 'Evidence-based Child Health' course run by the Centre for Evidence-based Child Health.
