My key areas of research expertise are in the design, conduct and transparent reporting of randomized trials and systematic reviews. I have published a number of research studies in these areas including the development of key reporting guidelines such as the CONSORT Statement and PRISMA for Abstracts.
I have a particular interest in clinical trial registration, data sharing, transparent reporting of clinical trial protocols, development of core outcome sets, pilot trials and trials of complex interventions. I am a Cochrane editor, associate editor for the journal Research Integrity and Peer Review, sit on the editorial board for the journal Systematic Reviews and am a member of the advisory board for Current Controlled Trials, NIHR Health Technology Assessment Clinical Evaluation and Trials Board and the IDEAL Collaboration. I regularly carry out peer review for high impact medical journals and various funding bodies (e.g. NIHR and Medical Research Council).
