Tim Peters is Professor of Primary Care Health Services Research at Bristol Dental School, having held many leadership roles including Head of Schools, Research Director for the Faculty of Health Sciences and Interim PVC for Research and Enterprise at the University of Bristol. A statistician and trialist with over 40 years' experience of epidemiology and research on health and health services, mostly in primary care, his research interests focus on community-based evaluations of health interventions, ranging from surgical and medical procedures through to the organisation of health care services. Many of these evaluations involve randomised trials conducted by multidisciplinary research teams including quantitative and qualitative methodologists. His particular areas of interest are mental health and chronic disease. Tim has also conducted research on the methodology of trials, especially where groups of individuals are randomised (cluster trials) or where there is interest in exploring the extent to which interventions confer greater benefit to some individuals than to others (subgroup analyses). A further priority in his career has been the development and supervision of other researchers from a variety of backgrounds – Tim has supervised 20 doctoral degrees amongst a total of 23 research degrees undertaken by doctors, nurses, other health care professionals and research methodologists. Tim has extensive experience of being a member of and/or chairing strategy and grants committees for applied health research and methodology, covering RCTs, programme grants, fellowship proposals and research infrastructure funding, for organisations including the MRC, NIHR, Academy of Medical Sciences, Wellcome, Health and Care Research Wales, Health Research Board in Ireland, Marie Curie, Macmillan Cancer Support and Dimbleby Cancer Care. He was a member of sub-panels in RAE2008, REF2014 and REF2021. He holds Honorary Fellowships of the Royal Colleges of General Practitioners and of Speech and Language Therapists, is an NIHR Senior Investigator (Emeritus) and is a Fellow of the Academy of Medical Sciences.
