In January 2016, Professor Toby Prevost was appointed to a Chair in Medical Statistics and Clinical Trials at Imperial College London, and to be the Head of Statistics in the Imperial Clinical Trials Unit.

His research interests fall within the design, conduct, evaluation and meta-analysis of trials of public health interventions and clinical interventions,  and he is an experienced researcher, with a Scopus citation H-Index of 38 co-authored publications cited at least this number of times.

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 the therapeutic areas of ophthalmology and rheumatology, and in clinical trials from early phase (trials of safety) to late phase (trials of effectiveness), and in the implementation of adaptive methods in trials.

Previously he worked at the University of Cambridge. Here he became experienced in statistical consulting with clinical researchers, in 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 now its retinal consequences.

He worked in posts at Cambridge as:

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

- a Consulting Medical 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 Unit lead for Statistics within the General Practice and Primary Care Unit's Statistics and 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.

He held an honorary post from 2007 to 2012 with the University College London Department of Pathology, responsible for statistical modelling in collaborative research investigating the potential of cell-cycle biomarkers to predict the development and progression of cancer.

After 2009 he held an honorary visiting senior fellow post at the University of Cambridge in the Department of Public Health and Primary Care, continuing his involvement in complex intervention trials in smoking cessation, physical activity, and medication adherence.

Professor Prevost has been a member of the NIHR Public Health Research funding board since 2014, and was a member of the Royal Statistical Society Primary Health Care committee from 2002 until 2013. He was a member of the NICE Public Health Interventions Advisory Committee (2008-2013), and since 2013 the NICE Public Health Advisory Committee. In 2017 he was appointed as Expert advisor for the NICE Centre for Guidelines.
