Biography


I joined the Open University Statistics Department in October 2007 as a PhD student, supervised by Prof. Chris Jones. My thesis is entitled "Parametric quantile regression based on the generalised gamma distribution". In March 2011, I was appointed a Research Associate at the Statistics Department where I am working on a three-year project entitled "Statistical outbreak detection methods for large multiple surveillance systems" with Prof Paddy Farrington (Principal Investigator), Prof. Paul Garthwaite (co-Investigator) and my colleague Dr. Doyo Gragn Enki.



Research


  • Generalised linear models (GLMs): I have done research on this topic, in particular ANOVA and ANCOVA, during my BSc. At the moment, I continue to work with GLMs while exploring the regression-based Farrington method for outbreak detection of infectious diseases. We aim to extend this approach and introduce new methods for outbreak detection.
  • Quantile regression and distributions: I explored the generalised gamma distribution deeply in my PhD thesis regarding maximum likelihood estimation. We looked at its different reparametrisations and analysed its asymptotic properties. Inspired by the generalised gamma, we developed a new distribution with interesting properties. We put the generalised gamma distribution in a quantile regression context while passing through all different stages of parametric modelling from model estimation, to model selection, to developing a goodness of fit test. We reviewed quantile regression methods, implemented a parametric approach using the generalised gamma and plotted quantiles for reference charts.
