Richard is a biostatistician with over twenty-years experience of methodology innovation and application. He is an expert on methods for meta-analysis, risk prediction and prognosis research. In meta-analysis, he specialises in methods for synthesising individual participant data (IPD), and is lead Editor of the book “Individual Participant Data Meta-Analysis: A Handbook for Healthcare Research”, published by Wiley in 2021.
In prognosis, Richard co-leads the PROGRESS initiative (PROGnosis RESearch Strategy), that seeks to improve the standards of prognosis research, including the development and validation of risk prediction models. A major focus is his work on sample size calculations for developing and validation prediction models. He is the lead Editor of the book ‘Prognosis Research in Healthcare: Concepts, Methods and Impact’, published by Oxford University Press in 2019.
Richard is also a senior member of the steering committee for TRIPOD, which produce reporting guidelines for prediction model studies, and founder and co-convenor of the Cochrane Prognosis methods group, which produce guidance for undertaking systematic reviews of prognosis studies.
