Dr Clemence Leyrat MSc PhD

Research Fellow in Statistics


After studying cognitive sciences at the University of Bordeaux (France) from 2005 to 2009, I obtained an MSc in Biostatistics at the Bordeaux school of Public Health in 2010. I then completed a PhD in Biostatistics at the University Paris Diderot in 2014 on the use of propensity score methods for cluster randomised trials, under the supervision of Bruno Giraudeau. During my PhD, I was involved in the statistical analysis of observational studies and clinical trials and taught statistics applied to biology and psychology. From 2014 to 2015, I did post-doctoral research in collaboration with the Hospital of Tours (INSERM CIC 1415 France) and Queen Mary University of London (Pragmatic Clinical Trial Unit).




 I am currently working on handling missing data for propensity score estimation in the context of electronic health records. I am also interested in the methodology of cluster randomised trials and causal inference (CACE analyses, instrumental variables).
