I am a trial statistician and methodologist in the International Statistics and Epidemiology Group (ISEG). My research focuses on developing statistical methods for use in cluster-randomised trials, with a special interest in stepped-wedge trials. I completed my PhD at the school in 2017. My PhD focused on statistical methodology to improve the design and analysis of stepped-wedge cluster-randomised trials. Previously, I have worked at the MRC Clinical Trials Unit at UCL.

Teaching
I co-organise a short course in the Design & Analysis of Cluster Randomised Trials and Stepped Wedge Trials. I also teach on the distance learning module Cluster Randomised Trials (CTM209) and face-to-face Clinical Trials module.
Research
My research focuses on statistical methodology for cluster randomised trials. Much of my work focuses on the stepped wedge trial design and developing robust methods of analysis. I help to maintain a website providing guidance to researchers on conducting cluster randomised trials. I was the a statistician for a recently completed cluster randomised trial evaluating the impact of an electronic monitoring box aiming to improving adherence to tuberculosis treatment in China.
