Research interests

  • Predator-prey interactions
  • Predator-predator interactions
  • Behavioural ecology
  • Conservation biology
  • Ecology of bisexual-unisexual salamander complexes

My research addresses theoretical and applied questions in terrestrial ecology. I am particularly interested in predator-prey interactions and seek to understand ecological and evolutionary mechanisms which operate at the interface of behavioural ecology and population biology. I work primarily with amphibian and insect systems, because these groups are particularly amenable to experimental manipulations in both the field and laboratory. Both of these taxonomic groups also face a number of emerging threats posed by rural and urban landscapes, and as a result my research has increasingly adopted a conservation theme.
