I am a Statistician and Mathematical Modeller Research Fellow in the Department of Infectious Disease Epidemiology. I am also involved with the Statistics, Modelling and Economics Department at Public Health England.

I have a number of years experience working on a wide range of projects across government and academia in defence and health.

I studied mathematics and statistics at the University of Newcastle-Upon-Tyne and obtained a PhD in applied probability from the University of Liverpool. After working for the Ministry of Defence for several years, applying novel Bayesian Inference ideas, I moved back into academia and the field of public health in 2010.

My general fields of interest include:

  • Operational research
  • Health economics
  • Survival analysis and multistate models
  • Epidemiology
  • Small area estimation

My current methodological interests include:

  • Care pathway analysis
  • Excess length of stay estimation
  • Cost-effectiveness
  • Multi-level modelling of spatio-temporal data, including aggregation of disparate sources
  • Discrete event simulation (DES)

 My current application areas include:

  • Tuberculosis (latent and active cases)
  • Healthcare-acquired infections
  • Sexually transmitted infections (principally Chlamydia)
