David Cromwell BSc MSc PhD

Professor of Health Services Research


I studied mathematics at Warwick University before completing a Masters degree in Operational Research at Lancaster University. On graduating, I had various analytical jobs in health care organisations in the UK, the Netherlands and Australia. For 10 years, I was a researcher at the University of Wollongong, Australia, undertaking projects on various topics, including health care financing, and the coordination of care. I gained my PhD while at Wollongong. Before joining the LSHTM, I worked at the UK Healthcare Commission.




On the Public Health MSc, I am the organiser of Healthcare Evaluation and a seminar leader for Health Services. I also teach on courses about critical appraisal of the literature and statistics for The Royal College of Surgeons of England.

I am interested in supervising research degree students who wish to investigate how best to evaluate the performance of health services (notably surgery) using observational data (such as clinical or administative databases).


My research interests sit under the broad heading of improving the quality and use of information in the delivery of health care. This has involved developing quantitative models to aid health care management, evaluating health-related information systems, and undertaking statistical analyses to inform quality improvement initiatives or policy decisions. My current position as Director of the Clinical Effectiveness Unit of The Royal College of Surgeons of England means this general interest now focuses on issues related to evaluating the effectiveness of surgery.
