I am a Senior Statistician at the MRC Biostatistics Unit, University of Cambridge.  I graduated in Mathematics, followed by a PhD in Biostatistics from the University of Cambridge, and then worked as a Research Associate at Imperial College London.  My work involves development and application of statistical methods to inform population health.  My research interests include Bayesian methods for combining multiple data sources and quantifying uncertainty, Value of Information approaches for prioritising research, survival modelling, multi-state modelling and longitudinal data.  I have developed widely-used statistical software packages, including “msm” for multi-state modelling and “flexsurv” for flexible survival modelling, in R.  I regularly teach short courses in Bayesian modelling. I am an Associate Editor of the journal Biometrics.
