My research has a strong focus on using anonymised, administrative data to address clinical and policy questions for children and families. Examples include the ECHILD Database linking hospital data to education data for all children in England, data linkages to assess maternal health needs of mothers involved in family court proceedings, home visiting services for teenage mothers. I contribute to research on record linkage methods, including leading two multicentre trials with consented linkages for long-term follow up from multiple data sources. I have also established national linked data resources combining infection surveillance and clinical records across England to generalise trial findings to changing infection rates in real-world practice and am supervising a study to reactivate dormant trials through unconsented, record level linkage of education data to data from trials conducted over the past three decades, to evaluate long-term cognitive outcomes in adolescence.
My team have developed whole country, standardised electronic cohorts to compare maternal and child outcomes in England, Scotland, Ontario, Sweden and Australia. The group has also developed and validated approaches to coding for a range of conditions in children and young people, with a focus on adversity, child maltreatment and family violence.
My goal is to widen the use of health and non-health administrative data to enable research to address health within families.

My recent work has focused on measuring and addressing physical and mental health inequalities, particularly for vulnerable and hard-to-reach groups such as homeless people and women with substance misuse.
I have a PhD in epidemiology, which formed part of the PRIMROSE program of work to predict and manage cardiovascular risk in people with severe mental illness, such as schizophrenia and bipolar disorder. My PhD research used UK primary care data from The Health Improvement Network (THIN) to investigate inequalities in statin prescribing and provides the first estimates of the effectiveness of statins for reducing first myocardial infarction and stroke in people with severe mental illness.

My research focuses on using routinely collected health data (including birth and death certificates, hospital admission records and general practice databases) for child health research. I have used these data to estimate the effectiveness of influenza vaccines, determine the role of chronic conditions in childhood mortality, and carry out international comparisons of childhood morbidity and mortality.

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 have also carried out several studies of respiratory syncytial virus epidemiology, and antibiotic prescribing in children. I am the principal investigator for the MRC-funded Air Pollution, housing and respiratory tract Infections in Children: NatIonal birth Cohort study (PICNIC) study.
My research programme also involves analyses to examine the impact of health inequalities (due to disability, ethnic group/migration status, or family socio-economic status) on children and how these can be mitigated. I am the lead for administrative data analyses, and deputy lead of the long-term conditions theme of the NIHR Children's Policy Research Unit (https://www.ucl.ac.uk/children-policy-research), and I lead the UCL programme of work for the NIHR School for Public Health Research 'Harnessing data to Improve Child Health' project (https://sphr.nihr.ac.uk/research/children-young-people-families/harnessing-data-to-improve-child-health-wp2/).

My methodological research focused on the development of statistical methods for data linkage, and particularly for evaluating the quality of linkage. I aims to develop methods to exploit the rich data that are collected about populations as we interact with services throughout our lives. My work facilitates the wider use of these population-based administrative and electronic data sources for epidemiological research, to support clinical trials, and to inform policy. I am a co-investigator on the Health Data Research UK - London site.
My applied research focuses on exploiting existing data sources to improve services for mothers and families, and particularly vulnerable families. My aim is to improve our understanding of the health of individuals from birth to young adulthood. My current research links data from health, education and social care at a national level, in order to determine outcomes of an early intervention for first time teenage mothers, and to explore variation in Health Visiting across England. I am passionate about increasing the public understanding of using administrative data for research.
My work involves collaborations with a number of key stakeholders for national data, including the Office for National Statistics, NHS Digital, Department for Education and Public Health England. I am a member of the Confidentiality Advisory Committee, a national regulatory body responsible for overseeing access to identifiable data for research.

My recent work includes joint multivariate response modelling for exploring the association between growth trajectories and health outcomes, and estimating trends in cardiovascular disease risk factors in adults and children in the UK and the impact of changes in body sizes using multiple studies/cohorts. I am also interested in adverse childhood experiences (abuse and maltreatment), child-to-adult development and adult health outcomes.

- Read more about Dr Ania Zylbersztejn
My research interests include international comparisons child health, epidemiology of respiratory syncytial virus, and health of children with learning disabilities and complex health needs. My PhD used national birth cohorts from administrative health records to compare mortality in children aged less than 5 years old in England and Sweden. I have worked on the first community-based serological survey of RSV in the UK which used 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.

My PhD project is supervised by Katie Harron, Ruth Blackburn and Rob Aldridge from UCL Institute of Health Informatics, I would be assessing and evaluating data linkage of the Million Migrant Study (linked administrative data in 1.5 million migrants in the UK), UK Longitudinal Linkage Collaboration (UK LLC, linkage of 20+ UK longitudinal cohorts with NHS health administrative data), and ECHILD, using Splink, an Open-source Python library developed by the Ministry of Justice. I hope to shed light on, and suggest alternatives to the practices in data linkage that might lead to biases that disproportionately exclude marginalised communities, such as people from minority ethnic groups, in health research.
My background is in mental health research and psych/social epidemiology. I previously worked at King’s College London, ESRC Centre for Society and Mental Health as a data scientist/research assistant. I hold an MSc in Clinical Mental Health Science from Division of Psychiatry, University College London.
