Profile

I joined CTRU as a Medical Statistician in October 2011. Before that I graduated with a BSc degree in Economics and Mathematics and an MSc in Statistics with Medical Applications from The University of Sheffield. I have also worked for the NIHR Research Design Service Yorkshire and the Humber (RDS-YH) and in the Cancer Clinical Trials Centre, Sheffield.

Current projects

I am involved in the following projects:

ASPECT - Alleviating Specific Phobias Experienced by Children Trial
The PRIEST Study: Pandemic Respiratory Infection Emergency System Triage
The PITSTOP Study - Pllonidal sinus Treatment: STudying the OPtions
ASTIClite - Autologgous Stem cell Transplantation IN refractory Crohn's disease - Low Intensity Therapy Evaluation

Section

I am based in Design, Trials and Statistics.

Research interests

Clinical trials methodology
Cluster randomised controlled trials and clustering in individually randomised controlled trials
Multiple imputation for dealing with missing data
Design and analysis of pilot trials
Complex interventions
