My primary role is Director of the Centre for Bayesian Statistics in Health Economics (CHEBS). I graduated from Brunel University in 1982 with a BSc in Statistics/Mathematics. After graduating, I worked in the pharmaceutical industry for 24 years, including at SK&F Research Ltd (1982 – 1986), Wellcome Research Laboratories (1986 – 1995), GlaxoWellcome (1995 – 1996) and AstraZeneca R&D Charnwood (1996 – 2006). During this time I gained experience in the design and analysis of pre-clinical studies and in all phases of clinical drug development, and held a variety of management positions. In 1998, I assumed a technical role in the development and application of statistical methods to improve the drug development process, with a particular interest in Bayesian methods. During this time, I became interested in the application of Bayesian methods in health economics and was actively involved in the creation of CHEBS. My PhD was on latent variable modelling of effectiveness and resource use data in cost-effectiveness analyses of clinical trials. I moved to the University of Sheffield in November 2006 to provide leadership to CHEBS and further develop my Bayesian interests.
