Research projects

I work on the population dynamics and ecology of social insects. Invasive ants and social wasps in the Pacific region are a particular focus. More recently my group has started examining the role of pathogens in social insect population dynamics, and we have also begun work on honey bees as a model system for understanding pathogen and host interactions. We are examining interactions between bacteria and viruses in honey bees as a method of mitigating the effects of parasitic Varroa mites. Our research projects integrate a range of techniques including statistical modelling procedures, isotopes, and molecular genetic analyses.

Our work spans the spectrum from very applied entomology (e.g. invasive ant or wasp control) to much more theoretical or conceptual work (e.g. wasp learning and foraging behaviour). Other work examining ecological or evolutionary theory include projects examining how humans have inadvertently driven positive selection for invasive genotypes of Argentine ants. At the 'front end' of our applied work is Pacific Biosecurity led by Dr Monica Gruber. We started Pacific Biosecurity as a not-for-profit organisation with the goal of build ing resilience to the threat of invasive insects throughout the Pacific region.
