    Personal profile

    Biographical details

    Toby Prevost was appointed in 2020 to the newly created Nightingale-Saunders Chair of Complex Clinical Trials and Statistics, King's College London within the Florence Nightingale Faculty of Nursing, Midwifery and Palliative Care.


    He is the Director of the Nightingale-Saunders Clinical Trials and Epidemiology Unit, established in May 2020, which is a specialist faculty-based section of the King's Clinical Trials Unit, involved in the funding application for, and delivery of, national and international studies, and in the development of an educational clinical trials programme in the Faculty:


    Toby was preceding this (2016-2020) a Chair in Clinical Trials and Medical Statistics at Imperial College London, and as Head of Statistics in the Imperial Clinical Trials Unit. From 2018 he was Director of the Imperial Statistical Advisory Service. He was an Honorary Visiting Professor at Imperial College London (2020-2023).


    Prior to this, Toby was appointed to a Readership post at King's College London in 2009, within the Primary Care and Public Health Sciences Division, Faculty of Life Sciences and Medicine. He was the Deputy Director of the newly formed Unit for Medical Statistics, engaged in clinical trials and statistical consulting for the design of medical research studies.


    In 2012, Toby was promoted, at King's College London, to Professor of Medical Statistics. His inaugural lecture summarises his collaborative research to this point, largely in the planning, delivery and evaluation of complex and lifestyle health interventions in clinical trials of behavioural and clinical outcomes in diabetes and related conditions.


    Before this he was a Senior Medical Statistician (2002-2009) and Medical Statistician (1991-1993 and 1996-2002), principally involved in clinical trials, developing interests in cluster randomised trials, trial design, complex intervention trials, and statistical consulting, in the Department of Public Health and Primary Care at the University of Cambridge, across the Primary Care Unit and the Centre for Applied Medical Statistics.


    He was seconded to a Senior Research Scientist post (2002-2006) in the Cambridge MRC Biostatistics Unit led by Professor Simon Thomson, via an MRC Group Cooperative grant for complex interventions in primary care led by Ann-Louise Kinmonth, the Foundation Professor of General Practice at the University of Cambridge.


    This MRC grant allowed him to develop two areas of methodological interests in collaboration with other statisticians:


    - with Professor Simon Thompson and Dr Rebecca Turner --- in designing cluster randomised trials with greater certainty of the statistical power to detect intervention effects. 


    - with Professor David Spiegelhalter --- in multivariate meta-analysis of correlations between constructs (variables) in order to understand the basis of, and support for the Theory of Planned Behaviour, which was assumption underlying many of the developed complex interventions intending to change lifestyle behaviours, such as physical activity.


    Toby set up a related Statistical Modelling Group within the University's Primary Care Unit undertaking primary care trials, and statistical research via a PhD studentship. This extended causal inference methods from the standard univariate (one outcome variable at a time) method to a multivariate approach (combine several related outcomes together), thereby strengthening the information to be able to then understand which components of a complex intervention may have led to the randomised result.


    Toby studied at the University of Southampton, completing a BSc in Mathematics with Statistics (1990), MSc in Statistics with Applications in Medicine (1991), and PhD in Social Statistics (1996) comparing a Bayesian approach to traditional approaches to the multilevel analysis of binary child mortality outcome data which clusters in families and is associated with short birth spacing, using data from the 1988 Tunisian Demographic and Health Survey.


    In between his MSc and PhD, Toby was the statisticial member of the 7-year longitudinal follow-up of the nationwide Health and Lifestyle Survey, giving early experience of working in a multidiciplinary research team which included a nutritionist, physiologist, sociologist, psychologist, psychiatrist and data manager.


    Toby has served on national committees drawing on his interests in research design and evidence synthesis and its interpretation - the combination (meta-analysis) of published research evidence:

    the NICE Public Health Interventions Advisory Committee (2008-2013); the NICE Public Health Advisory Committee (2013-2020); as Expert Panel Member of the SACN (Scientific Advisory Committee on Nutrition) with NICE Rapid Guideline for Vitamin D and Covid-19 (2020); the NIHR Public Health Research Funding Committee (2014-2020); the NIHR Covid-19 Recovery and Learning Funding Committee (2020); a Cancer Research UK Prevention & Population Expert Review Panel (2021); on a European Funding Board for sub-macular haemorrhage for EURETINA/Fight for Sight; and as an NIHR Public Health Research Applications and Design Advisor (2020-2023)

    Regionally, he has contributed as a London Research Design Service advisor (2011-2015 and 2022-2023); an Independent Advisory Board member on the NIHR Central-region PHIRST (Public Health Interventions Responsive Studies Team) led by the University of Hertfordshire; and on committees as an independent member overseeing >30 clinical trials around the country.


    He has experience in complex interventions trials, including primary care prevention trials of interventions to support change in lifestyle behaviours such as physical activity (preventive of Type 2 diabetes) and smoking cessation, and medication adhererence, and complex interventions for improving breathlessness in palliative care.


    His experience in clinical treatment trials is broad though with a focus of application within ophthalmology, rheumatology, diabetes, prevention of weight gain, and, within palliative care: breathlessness, rehabilitation and cancer management.


    He also has some experience in early phase trials, including Phase I to II dose-finding trials that are 'adaptive', in learning as they go along and being able to be more efficient in establishing safe doses, with the involvement of fewer patients.


    He has been involved a wide range of research collaborations, leading to 200 published co-authored research papers, with a Scopus H-Index of 56 (this being the number of these publications that have been cited at least this same number of times).


    This is a selection of research collaborations (with statisticial co-workers shown in bold):
