I have been worked at the University of Liverpool since 2001, and my research interests have focused predominantly on trial methodology relating to outcomes and adherence. I have extensive experience working in the design, conduct and analysis of randomised trials within the Clinical Trials Research Centre and previously as part of the Liverpool Cancer Trials Unit. I recently completed an NIHR Doctoral Research Fellowship investigating the use of causal methods to account for deviations from randomised treatment in the analysis of randomised trials. I also interested in research relating to trial outcomes, and was involved in the ORBIT (Outcome Reporting Bias In Trials) project, helping to develop the study classification system for missing or incomplete outcome reporting in reports of randomised trials. I am now working on the development of a classification system for outcomes included in trials, systematic reviews and core outcome sets, in association with the COMET (Core Outcome Measures in Effectiveness Trials) initiative.
