I am Director of the Health Services Research Unit and Professor of Health Care Evaluation. I also direct the Aberdeen Health Technology Assessment Group, which is the only academic centre in Scotland responsible for providing technology assessment reports for the UK National Institute for Health and Care Excellence.
I have wide ranging research interests in health services research with expertise in service improvement research, surgical trial evaluation, and quasi-experimental study designs and as statistical editor for the Cochrane Effective Practice and Organisation of Care group I have led the worldwide development of systematic review methodology for interrupted time series designs. I serve on several national and international committees and was an inaugural member of the Royal Society of Edinburgh Young Academy of Scotland.
- BSc Mathematics and statistics1993 - University of Edinburgh

I am currently accepting PhDs in Nutrition and Health, Dentistry.
Please get in touch if you would like to discuss your research ideas further.
Nutrition and HealthSupervising
SupervisionI provide PhD supervisory support for full or part-time PhD students. Some recent examples include:
- Complex designs in randomised clinical trials – a case study in dentistry - Beatriz Goulao
- Interrupted times series (ITS) evaluation - Jemma Hudson
- What are the personal, clinical and social impacts of longer waiting times? A multi-methods study - Elisabeth Kirchner
- Optimising the responsible use of antibiotics - Shazia Yousuf
Funding and Grants
In terms of research grant awards, I have personally been involved as chief investigator or principal applicant on a portfolio of national and international studies generating in excess of £30 million, with £20 million in the last 5 years. The projects include a mix of large scale international trials and methodological studies funded from a variety of sources – all the studies are healthcare policy relevant and of national or international significance.
