I am interested in the use of computers to assist clinicians in making decisions, and also in the development of intelligent training tools. These are quite different applications but the technology required is similar. I have a special interest in the application of these systems to radiology and have been involved in a number of evaluations of Computer Aided Detection in radiology. I also have a student using mathematical modelling to look at the impact of various parameters on life expectancy. The idea being to combine a variety of 'risk equations' developed by epidemiologists into a overall measure.
