Biographical information

I obtained my BSc (1969) and PhD (1974) in Statistics from the University of London. Between these two bouts of study, I worked for two years as a practising statistician at the Central Electricity Generating Board. I began my academic career at the University of Dundee in 1973, moving to Warwick University in 1975. I became Professor of Statistics at the University of Nottingham in 1990 and moved to Sheffield in 1999. In 2008 I formally retired from my post at Sheffield, and took on a part-time role to complete the "Managing Uncertainty in Complex Models" project. I also now have an honorary position as Industrial Fellow at Warwick University.

I have been able to serve the academic statistics community in a variety of capacities. In particular, I have served on the Research Section Committee and the Council of the Royal Statistical Society, and the Board of the International Society for Bayesian Analysis. I have been a member of the Peer Review College of the Engineering and Physical Sciences Research Council and the College of Experts of the Medical Research Council.

Being semi-retired from academic work frees me to become more active as a consultant to government and industry. I am a Chartered Statistician, which is a qualification administered by the Royal Statistical Society that recognises my expertise as a practising statistician.

Research interests

My research is in the theory and applications of Bayesian statistics. On the methodological side, my main research area is in managing and quantifying uncertainty in the use of complex mechanistic models. I also have interests in model comparison, elicitation of expert knowledge, conflicting information and inference about functions. I have been involved in many applications, particularly in environmental statistics, asset management and health economics.
