After completing a BSc in Mathematics and an MSc in Statistics and Management Science at the University of the West of England, Bristol, I began my career as a clinical trial statistician. Firstly, at Bangor University before moving over to The University of Sheffield. I have a range of experience designing and analysing clinical trials as well as other study designs. I also work ad-hoc for the Research Design Service where I offer general study design advice as well as specific statistical aspects such as sample size calculations.  

I started an ESRC White Rose funded doctoral fellowship with an MA in Social Research followed by the PhD project which started in October 2021.

Research interests

PhD Title: How can benefit-risk methods be used when setting the non-inferiority margin within non-inferiority clinical trials to account for the benefit of a secondary outcome of importance?

My PhD project combines my research interests of non-inferiority clinical trials and benefit-risk assessment. Other research interests of mine are pilot and feasibility studies as well as the importance of including patients and the public within research and the difficulties surrounding this. 

Current Projects:

  • AWARE-IBD: Putting people with inflammatory bowel disease (IBD) in control of their care. 
  • BASIS: Bracing Adolescent Idiopathic Scoliosis
  • BRAINS: Benefit-Risk Assessment to Inform Non-Inferiority and Superiority Study Designs 
  • INITIAL: Involving patients and the public In sTatistIcal Analysis pLans.
