Siobhan Creanor's research focuses on the design, analysis, and reporting of studies in healthcare settings, with substantial expertise in Bayesian statistics for cluster randomised trials, trial protocols, feasibility studies, cost-effectiveness analyses, and process evaluations. She collaborates on interventions targeting multiple sclerosis, stroke, dementia, Parkinson's disease, alcohol-related harm, obesity prevention, severe mental illness, and child health. Notable publications include the cluster randomised controlled trial and economic evaluation of the Healthy Lifestyles Programme (HeLP) for preventing childhood obesity (Lancet Child & Adolescent Health, 2018), the PARTNERS2 trial on primary care-based collaborative care for severe mental illness (British Journal of Psychiatry, 2023), the PD STAT randomised trial evaluating simvastatin for Parkinson's disease (JAMA Neurology, 2022), the DEXACELL trial protocol for adjunctive dexamethasone in cellulitis (BMJ Open, 2025), and the vestibular rehabilitation trial in multiple sclerosis. As Director of the UKCRC-registered ExeCTU, established in 2015, she oversees high-quality multi-centre trials across portfolios including dementia, mental health, diabetes, emergency medicine, COVID-19, and complex interventions, contributing to improved clinical practice through rigorous methodology.
