Rhiannon is a Research Fellow working within the Surgical Innovation theme of the National Insititute for Health Research (NIHR) Bristol Biomedical Research Centre (BRC). Rhiannon's research is focused primarily on health services research and clinical trial methodology. Her areas of expertise are in outcome selection, measurement and reporting in randomised controlled trials, with a specific interest in patient reported outcomes and trials in surgery.

Rhiannon has recently completed a PhD exploring 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). She is also exploring 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 in 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).
