Professor Sir Richard Peto
Professor of Medical Statistics & Epidemiology at the University of Oxford. Since 1985, he and Rory Collins have been co-directors of the CTSU. Professor Peto's work, in collaboration with others in the CTSU, has included studies of the causes of cancer in general, and of the effects of smoking in particular, the conduct and interpretation of large-scale prospective studies, and the establishment of large-scale randomised trials, and meta-analyses of trials, of the treatment of heart disease, stroke, breast cancer and several other diseases. He has been instrumental in introducing combined 'meta-analyses' of results from related trials that achieve uniquely reliable assessment of treatment effects. He was elected a Fellow of the Royal Society of London (for the introduction of meta-analyses) in 1989, and was knighted (for services to epidemiology and to cancer prevention) in 1999.
