I joined the CTRU as a Medical Statistician in July 2017 after working for NWORTH (Bangor University's Clinical Trial Unit) as a Trial Statistician. I have a BSc in Mathematics and an MSc in Statistics and Management Science, both from the University of the West of England, Bristol. I currently work on a number of clinical trials, as well as methodology projects and as a statistical advisor for the Research Design Service.
I am currently involved with the following projects:
•CFHealthHub Data Observatory - A Quality Improvement project and Trials within Cohort platform for Cystic Fibrosis
•MAGIC – Melatonin for Anxiety prior to General anaesthesia In Children): A Randomised Controlled Trial of Melatonin Versus Midazolam in the Premedication of Anxious Children Attending for Elective Dental and ENT Surgery Under General Anaesthesia
•DAFNEplus - Developing and trialling the DAFNEplus (Dose Adjustment for Normal Eating) intervention. A lifelong approach to promote effective self-management in adults with type 1 diabetes.
•BRAINS - Benefit-Risk Assessment to Inform Non-Inferiority and Superiority study design: Guidance on the optimal design within different-in-kind of comparisons
•PoPSTER - Patient preferences and current Practice for adults with STERoid resistant ulcerative colitis.
My areas of research interests are: the design of pilot and feasibility studies, sample size calculations for ANCOVA models and multi-arm studies and the designing studies using a benefit-risk trade-off.
