Research interests

I am a Mathematical Epidemiologist in SRUC’s Disease Systems team. My background is in mathematical physics, although my current research interests are in mathematical modelling and statistical inference for the spread of disease. This is both methodological and applied. The applications are mostly in the areas of terrestrial agriculture and aquaculture, but I also have interests in wildlife and human epidemiology, particularly where these interact with each other or livestock (such as zoonoses, vector-bourne diseases and reservoirs of infection).

Methodological research:

  • Bayesian techniques for fitting stochastic process based epidemiological models
  • Diagnostic test response dynamics and inference
  • Quantification and epidemiological methods for genetic effects on disease resistance
  • Process based stochastic modelling techniques

Applications:

  • Aquaculture – identification and quantification of genetic effects on disease resistance, development of operational modelling approaches for deploying resistant stock, modelling of disease control
  • Bovine Tuberculosis – Parameter estimation for TB in badgers, origin of the perturbation effect in demographic processes, spatial models of disease spread
  • Paratuberculosis – Role of wildlife hosts in paraTB epidemiology, estimation methods for control efficacy, estimation of test characteristics for novel phage based assays
  • Parasite dynamics and ecology in grazing systems
  • Disease surveillance in wild and managed systems
