Paul’s main research interest is in clinical decision support systems which includes understanding theinformation needs of clinicians, designing tools to present relevant clinical information and assessing the effectiveness of technology designed to help clinicians make decisions. The main focus of my research has been in medical imaging. Two major projects involved (a) designing and building a system for the differential diagnosis of mammographic calcifications and (b) assessing the potential of a commercial system designed to alert radiologists to potential abnormalties. This research is developing in a new direction and I am now working on the development of a system to help train radiologists seeking to specialise in screening mammography. We hope to extend these ideas to other areas of radiology.
