I am interested in all areas of applied research in primary care.

I am particularly interested in the potential of primary care data to improve practice through innovative tools including software interventions. This includes the identification of undiagnosed conditions (cardiovascular disease, diabetes, cancer) to enable early intervention.

I am also interested in developing the evidence base for established interventions that we may take for granted. A recent example included the HTA funded ESTEEM trial (led by University of Exeter Medical School) which has investigated alternative triage arrangements for managing requests for same day appointments in general practice.

I have recently completed a large cluster randomised trial of an automated reminder intervention (AURAS-AF) to promote uptake of oral anticoagulants in individuals with atrial fibrillation and at risk of stroke. This was funded by NIHR and involved a collaboration between the Universities of Oxford, Birmingham and Nottingham, the NHS, and the clinical software supplier EMIS.

Current work includes the validation of a novel risk algorithm for undiagnosed bowel cancer based on primary care data.

I have experience of a range of methods including systematic reviews, epidemiological studies, randomised trials, and qualitative studies.
