Prior to this I worked as a consulting statistician and project statistician within the (now defunct) University of Cambridge Department of Public Health and Primary Care’s Centre for Applied Medical Statistics (CAMS) (1997-2000) and Epidemiology for Policy Group (2000-2001) respectively. I currently lead the Stratified Medicine Initiative at the Unit. Prior to this I worked within Professor Vern Farewell’s programme for “Statistical Modelling: theory and applications” which deals with methods of statistical inference for challenging data structures. However, I also collaborate with other senior scientists (present and former) in the Unit, in particular Professor Sheila Bird, Dr Daniela De Angelis, Professor Wally Gilks and Professor Carlo Berzuini.
