Research summary

My work focuses on use of administrative health records(e.g.: primary and secondary care records, birth and death certificates) tostudy health outcomes of children and their families. I currently work as part of the HOPE study which investigates the impact of adjustments for special educational needs or disability (SEND) on children’s health using linked education and health data from the ECHILD database.

Previously, I worked with data from primary and secondary care to explore mental andphysical health of children with learning disability or autism, their mothersand siblings (as part of the long-term conditions theme of the NIHR Children'sPolicy Research Unit). I also worked on epidemiology of respiratory syncytial virus (RSV) infections in children. I carried out the first community-based serological survey of RSV in the UK using linked serological samples, questionnaire data and administrative health records from the Born in Bradford cohort study. I also used routinely collected hospital records linked to pharmacy dispensing records to explore patterns of prescribing of palivizumab, a passive immunotherapy available to infants at high risk of severe infection, in English hospitals.

I am interested in international comparisons of child healthoutcomes. In my PhD, I compared mortality in children aged less than 5 yearsold in England and Sweden. I developed national birth cohorts fromadministrative health records in the two countries to determine the contributionof birth characteristics and socio-economic factors to excess child mortalityin England relative to Sweden. I also explored intercountry differences inmortality due to potentially preventable causes and I was involved in a projectcomparing recording of congenital anomalies in hospital records in England andScotland.

I completed a PhD in epidemiology at UCL Great Ormond Street Institute of Child Health and the Farr Institute of Health Informatics Research, in collaboration with the Centre for Health Equity Studies at Stockholm University. I used routinely collected health records to develop national birth cohorts in England and in Sweden, to determine why child mortality is nearly two times higher in England than in Sweden. Prior to the PhD, I studied MORSE at University of Warwick and I hold MSc in Medical Statistics from University of Leicester. My research interests include international comparisons child health, epidemiology of respiratory syncytial virus, and health of children with learning disabilities and complex health needs.
