Spread of non-native invasive and pest species

I lead projects modelling the dispersal, spread and impacts of non-native invasive plants and pest organisms. These models are important in understanding the biological processes driving invasion and for planning effective control strategies. Major science questions include:

  • Are large-scale patterns of invasion constrained by species dispersal, global transport networks and climate?
  • What are the best ways to conduct surveillance and control of invasive species?
  • What is the role of trait adaptation in promoting invasion?
