Teaching: Course Information


Research (click here to download PDF copies) My current research focus involves environmental and spatial statistics and toxicology concentrating primarily on assessing interactions and their effects on the environment and systems. Methods include likelihood methods, curvature and differential geometry; statistical modelling and simulation; sampling and optimal/experimental design; bioassay, relative potency and synergy (interaction); and general biostatistics, epidemiology, and bioinformatics. I also work in statistics education and medical/statistical ethics.
