Graham's PhD research (1971-74; Department of Brewing and Biological Sciences, Heriot-Watt University, Edinburgh) was on the mechanism of starch breakdown during cereal germination. He then moved to the Microbiology Unit, Department of Biochemistry, University of Oxford (1974-78) to carry out postdoctoral work on the developmental biology of spore formation in the bacterium Bacillus subtilis.
Having abandoned laboratory work, Graham retrained as an applied statistician (Department of Biomathematics, University of Oxford, 1978-79) and worked at the Institute of Psychiatry, University of London, for the next 17 years. He was at first the statistician in the General Practice Research Unit (from 1979 to 1983) and then Lecturer (1983-87) and Senior Lecturer in Statistics (1987- 93) in the Institute's Biometrics Unit. He took over the role as Head of the Unit in 1990, the year in which it became the Department of Biostatistics and Computing. Graham was Reader in Biostatistics from 1993 to 1996. During that period he was also the Institute's Director of Education.
Graham was appointed as Professor of Biomedical Statistics at the University of Manchester at the end of 1996.
He is the author of several applied statistics textbooks and was a founding editor of the international review journal Statistical Methods in Medical Research.
