Katie is an Associate Professor at the UCL Great Ormond Street Institute of Child Health. She completed her PhD on statistical methods for data linkage at UCL in 2014, and was subsequently awarded a Wellcome Trust fellowship. Katie’s research uses statistical methods to exploit the rich data that are collected about populations as we interact with health, social care, and educational services throughout our lives. She is particularly interested in the complexities of linking large datasets, evaluation of linkage quality, and the use of administrative data cohorts to support research into maternal and child health.
