I am a medical statistician in the School of Social and Community Medicine at the University of Bristol. I am currently focussing on developing and applying statistical methods in two particular areas:
* Instrumental variable methods for Mendelian randomization
* Meta-analysis of diagnostic accuracy studies
I have previously worked on meta-regression and methods for detecting bias in meta-analysis and maintain an interest in these areas.
I have written or co-written several add-on modules for the statistical software package Stata.
