After completing a BSc degree in Statistics at University College London (2010-13), Claire completed a two-year National Institute for Health Research (NIHR) methods fellowship at the Pragmatic Clinical Trials Unit (PCTU). As part of the fellowship Claire gained an MSc degree in Medical Statistics at the London School of Hygiene and Tropical Medicine (2013-14). Claire now works as a Statistician in the PCTU, with current research interests in both pilot and feasibility studies and cluster randomised trials. In particular, Claire is part of the group who produced papers on definitions of pilot and feasibility studies and the CONSORT extension for external pilot trials. She has been involved in leading several workshops on these topics, and is also an Associate Editor of the Pilot and Feasibility Studies Journal. Claire also organises the annual cluster meeting on Current Developments in Cluster Randomised Trials and Stepped Wedge Designs, and led the creation of two websites designed to support researchers in the design, analysis, and reporting of cluster randomised trials and pilot and feasibility studies.
