Research area

  • Application of statistics to environmental and ecological problems

Particular research interest in use of expert knowledge to inform statistical modelling using the Bayesian framework. Applications have included

  • bioregionalisation combining expert-derived boundaries with GIS data on broad environmental (eg geology, topography) and bioclimatic attributes
  • setting benchmarks on vegetation condition using expert knowledge
  • designing sampling protocol for monitoring microbial contamination levels in recycled water
  • habitat modelling for rare plants and animals, combining expert knowledge with site or landscape scale data (eg native thistle Stemmacantha Australis, Red Goshawk, brush-tailed rock wallaby Petrogale Pencillata, Macadamia)
  • modelling impacts of flow on native aquatic plant Vallisneria Nana.

Dr Choy has also recieved an ARC discovery grant on Bayesian priors: designing epidemiological study to quantify impact of ultrafine particles from traffic emissions on human health. Bayesian prior distributions

  • designing expert elicitation
  • software tools to support elicitation
  • encoding expert knowledge on skewed distributions
  • combining multiple expert opinions
  • stratification to improve habitat modelling.
