Visiting Senior Research Fellow
BSc MSc PhD
Toby joined the Department of Public Health and Primary Care in 1991 as the statistical member of the Health and Lifestyle Survey team. Research interests of the team included the characterisation of diet from food frequency questionnaires using principal components. After a PhD in Southampton involving an evaluation of multilevel modelling methods for the analysis of family-clustered child mortality, Toby returned to the Department in 1996 as a consulting statistician and then primary care trial statistician. He was promoted to Senior Research Associate in 2002 and led the Statistical and Modelling Group of PCU until 2009. This included a period 2002-2006 working in the MRC Biostatistics Unit in the areas of cluster randomised trial design, and multivariate meta-analysis for complex interventions.
In 2009, Toby moved to take up a Readership in Medical Statistics at King’s College London, and was promoted to Chair in Medical Statistics at King’s College London in 2012. In 2016 he moved to take up a Chair in Medical Statistics and Clinical Trials at Imperial College London, where he heads the Clinical Trial Statistics group and the Statistical Advisory Service. He continues in multi-disciplinary research in trials intervening on lifestyle behaviours with the PCU, and in clinical trials principally along the route of lifestyles through weight change and diabetes and its retinal complications.
Toby has been a member of the NIHR Public Health Research Board since 2014, and a member of the NICE Public Health Advisory Committee and its predecessor Interventions Advisory Committee since 2008. In 2017 he became an expert advisor for the NICE Centre for Guidelines.
