Gill is the Principal Statistician at the Bradford Institute for Health Research, with over 25 years’ experience in applied epidemiology and biostatistics, with a background spanning physiology, epidemiology, and statistics.
Her research focuses on the early-life determinants of health, with particular interests in childhood obesity, metabolic disease, and asthma and allergic disease, and in understanding how social, environmental, and clinical exposures shape health trajectories across the life course. Much of her work is based in ethnically diverse and socio-economically disadvantaged populations, using longitudinal cohort data, linked electronic health records, and experimental and quasi-experimental designs.
Gill is a Co-Investigator and Statistical Lead on several major NIHR- and MRC-funded programmes, including evaluations of city-wide air quality interventions, studies of multimorbidity in pregnancy, and large-scale analyses of the long-term impact of perinatal antibiotic exposure on childhood asthma, eczema and related metabolic outcomes. She also contributes to international collaborative grants focused on obesity prevention and maternal and child health data infrastructure.
Her methodological expertise includes longitudinal and multilevel modelling, prediction modelling, trajectory analysis, causal inference, and the analysis of routinely collected health data. A core aim of Gill’s work is to ensure that robust statistical evidence informs public health policy and interventions that improve outcomes for children and families across the life course.
