I have a PhD in Pure Mathematics from Imperial College London (Ergodic Theory) and a MSc in Medical Statistics from the London School of Hygiene and Tropical Medicine in September 2011.
I worked at the Pragmatic Clinical Trial Unit, Centre for Primary Care and Public Health, Queen Mary, as part of a three-year NIHR Methods Fellowship in Medical Statistics.
I have also experience in cost-effectiveness analysis of cluster randomised trial data.
I currently hold an MRC Career Development Award in Biostatistics.

I am a tutor on the School's short courses Statistical Analysis with Missing Data using Multiple Imputation and Inverse Probability Weighting and Causal Inference in Epidemiology: Recent Methodological Developments
I am interested in developing methods for estimating treatment effect when there is departures from protocol in a randomised trial (i.e. non-compliance and missing data) using Multiple Imputation. This work is in collaboration with Profs Michael Kenward and James Carpenter.
I am a member of the Centre for Statistical Methodology, and one of the co-ordinators of the missing data theme.
