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.
