Biography

Background

I am a statistician with interests in methods for improving the design and analysis of clinical trials. As well as working in methodology development I have a great interest in collaborating on real trials to apply new methods in practice.

I have been at Newcastle University since July 2017.

Areas of expertise

  • Biostatistics
  • Clinical trials
  • Novel trial design

Research

My research focuses on statistical methods for improved design and analysis of clinical trials. I am particularly interested in:

  1. Adaptive designs for clinical trials;
  2. Methods for incorporating biomarkers into clinical trials to stratify patients by treatment response;
  3. Improved methods for analysing composite endpoints, in particular ones with continuous components.
