Professor Toby Prevost was appointed to a Chair in Medical Statistics and Clinical Trials at Imperial College London in January 2016, and is the Head of Statistics in the Imperial Clinical Trials Unit. His research interests fall within the design, evaluation and meta-analysis of trials of public health and clinical interventions, and he has a Scopus citation H-Index of 35.

Prior to moving to Imperial he was Reader and then Professor of Medical Statistics at King's College London, (Inaugural Lecture) where he was the Deputy Director of the Unit for Medical Statistics, Co-lead in Methodology at the NIHR Biomedical Research Centre at Guy's and St Thomas's NHS Trust, and Co-director of the Statistical Consulting Unit at the Trust. Here he developed clinical trial collaborations principally in ophthalmology, rheumatology, and in early phase trials, and in the development of adaptive methods in trials.

Previously he worked at the University of Cambridge. Here he developed expertise in statistical consulting with clinical researchers, the application of statistical methods in medical research, and in trials principally of complex interventions applied across the pathway from modifiable lifestyle behaviours through to obesity and to diabetes and other health consequences. He worked in posts as:

-  a Health Survey Statistician (1991-1993) in the nationwide Health And Lifestyle Survey multidisciplinary team;

- a Consulting Statistician (1996-2002) in the Centre for Applied Medical Statistics, collaborating with clinicians in medical research across the University Clinical School at Addenbrooke's Hospital;

- a Unit and Trial Statistician (2000-2002) in General Practice and Primary Care Research Unit in trials within Type 2 diabetes and Cancer with Professors of General Practice: Head of Unit Ann-Louise Kinmonth, Jon Emery, Simon Griffin;

- a Senior Research Scientist (2002-2006) in the Cambridge MRC Biostatistics Unit undertaking Methodological Research with Professor of Biostatistics in cluster randomised trial design with Head of Unit Simon Thompson, and in multivariate meta-analysis for complex interventions with David Spiegelhalter.

- a Senior Medical Statistician, being Group leader for Statistics within the General Practice and Primary Care Modelling group (2002-2009), lead consulting statistician in the Centre for Applied Medical Statistics (2006-2009), and Statistical Co-investigator in clinical trials across public health, primary care and clinical settings.

He studied at the University of Southampton for a BSc in Mathematics with Statistics, MSc in Statistics with Applications in Medicine, and PhD in Social Statistics.

Professor Prevost serves on the NIHR Public Health Research funding board (since 2014), the NICE Public Health Advisory Committee (since 2008), and the Royal Statistical Society (Primary Health Care committee 2002-13).

He held an honorary post from 2007 to 2012 with the UCL Department of Pathology, collaborating in research investigating the potential of cell-cycle biomarkers to predict the development and progression of cancer.

Since 2009 he has held an honorary visiting post at the University of Cambridge in the Behavioural Science Group.
