Overview
I am a Senior Research Fellow in the Centre for Trials Research where I work as a medical statistician on the design, conduct, analysis, and reporting of randomised controlled trials and other well-designed studies.
My background is in applied statistics, but I work across a wide range of clinical areas including infections, neurodegenerative diseases, and population health, as well as on the advancement of clinical trials methodology, in particular efficient design methods such as adaptive designs.
I am the Deputy Director of the Research Design and Conduct Service (RDCS) for South East Wales, which works with NHS and social care staff to develop high-quality funding applications for innovative research projects in health and social care.
I co-lead the Adaptive Designs Working Group of the MRC-NIHR Trials Methodology Research Partnership together with Sofía Villar.
I am an Associate Editor for the peer-reviewed journal Trials.

Summary of my research
I currently work on a number of trials (including BATCH, PRECISE, PRONTO, TRIDENT, FLAME, TAPERS, SaFE, SWIS, LISTEN, PLACEMENT and DocTIS) and observational studies (including DOMINO-HD, PEACH, Family VOICE and PERCEIVE).
I have been actively involved in the ACE Project to develop an official CONSORT extension for clinical trials with an adaptive design, the PANDA Project to create an educational online platform about adaptive designs, and the CAT Project to develop best practice costing guidance for CTUs supporting adaptive design trials.
I have (co-)authored and/or am the maintainer of a number of R packages that are freely available on CRAN, including MAMS (multi-arm multi-stage studies), BayesMAMS (Bayesian multi-arm multi-stage studies), jocre (joint confidence regions), modest (model-based dose-escalation trials), ANOM (analysis of means) and simboot (simultaneous inference for diversity indices).
