Rhiannon is a Senior Research Fellow working within the Centre for Surgical Research and the Surgical and Orthopeadic Innovation theme of the National Insititute for Health Research (NIHR) Bristol Biomedical Research Centre (BRC). She is an Applied Health Services Researcher and methodologist, with expertise in outcome selection, measurement and reporting in early-phase studies and randomised controlled trials. Rhiannon has a specific interest in patient reported outcomes. Her current NIHR BRC projects focus on methods to improve the evaluation of surgical innovation. 

Rhiannon's PhD explored methods for improving the assessment of wounds for surgical site infection (SSI). Her work includes the development and validation of a new outcome measure for SSI for use after the patient has left hospital, suitable for patient or healthcare professional completion (the Bluebelle Wound Healing Questionnaire). Her PhD also explored the feasibility of using patient-taken images of wounds for remote wound assessment.

Previously (2009 to 2019) Rhiannon worked within the Medical Research Council (MRC) ConDuCT-II (Collaboration and innovation in Difficult and Complex randomised controlled Trials In Invasive procedures) Hub, part of the MRC Network of Hubs for Trials Methodology Research. Before joining the university, she worked for the NHS within the Clinical Trials Unit at the Bristol Haematology and Oncology Centre.

Rhiannon completed a BSc in Biological Science and Psychology at the University of Swansea (2002) and an MSc in Research Methods in Psychology at the University of Bristol (2006).
