Research summary

Katie’s research falls into two main areas. Her methodological research focuses on the development of statistical methods for data linkage, and particularly for evaluating the quality of linkage. She aims to develop methods to exploit the rich data that are collected about populations as we interact with services throughout our lives. Her 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. She is a co-investigator on the Health Data Research UK - London site.

Katie’s applied research focuses on exploiting existing data sources to improve services for mothers and families, and particularly vulnerable families. Her aim is to improve our understanding of the health of individuals from birth to young adulthood. Her 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. Katie is passionate about increasing the public understanding of using administrative data for research. 

Katie's 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. She is a member of the Confidentiality Advisory Committee, a national regulatory body responsible for overseeing access to identifiable data for research.
