Richard is a senior statistician at the Pragmatic Clinical Trials unit, and pursues a research programme at the forefront of innovation in the design of randomised evaluations of health technologies, including stepped wedge trials and other novel approaches to clustered evaluations. His work has been published in the BMJ, the International Journal of Epidemiology, and the Journal of Clinical Epidemiology, as well as Statistics in Medicine, and Statistical Methods in Medical Research. He has given invited talks at international conferences of the International Society for Clinical Biostatistics, Royal Statistical Society, and Society for Clinical Trials, and he is part of an international network of excellence in innovations in cluster randomised clinical trial methods, led from Monash University, Australia. He was recently awarded a Senior Fellowship by The Healthcare Improvement Studies (THIS) Institute, UK, to develop and promote innovation in clinical trial design as a key component of healthcare improvement science.

Richard did his PhD on statistical pattern recognition at the University of Cambridge, and has worked as a medical statistician at Cambridge University, King’s College London, and Imperial College London, as well as working for a year with the Government Statistical Service in the Department of Health. He joined Queen Mary University of London in 2010, where he had his first introduction to the world of clinical trials, which have been at the centre of his research and practice ever since.


Research Interests:

Rcihard's current research interests centre on stepped wedge and other cluster randomised trial designs. The selected articles listed in the ‘Publications’ tab may give more of a flavour. He was awarded a Senior Fellowship from The Healthcare Improvement Studies (THIS) Institute, which has allowed him time and space to write about the ideas that interest him, to work with applied healthcare researchers to implement new methods, and to learn from a dynamic and multidisciplinary academic community.
