Mr George Vamvakas
George joined KCL in 2014. He is a statistician and a part-time PhD candidate in the Department of Biostatistics and Health Informatics. Having worked as a health economist, George switched to statistics after completing the MSc in Statistics at Lancaster University. His work as a statistician is focused on the analysis of observational and randomised data from developmental studies. This has predominately involved the use of growth modelling, missing data techniques, and propensity score matching. His PhD is concerned with the prediction of individual standardised scores and growth characteristics, via structural equation models that utilise weights or auxiliary variables. Work on this will inform the construction of growth charts for language development using data from the SCALES study, a longitudinal survey of 4- to 12-year-old children. George is supervised by Prof. Andrew Pickles at KCL and Prof. Courtenay Norbury at UCL.
