Background
I am a Newcastle University Research Fellow in Biostatistics, interested in methodology for improving the design and analysis of clinical trials. As well as working on developing methodology, I am also interested in collaborating on real trials.
I have been in Newcastle since November 2018. Prior to this I was a Statistician at the MRC Biostatistics Unit, University of Cambridge.

Research
My research focuses on statistical methodology for improving the design and analysis of clinical trials. I am particularly interested in:
- Adaptive clinical trial designs;
- Early phase oncology trials;
- Crossover trial designs;
- Cluster randomised trials.
