Research Interest:
Population ecology: dynamics of small populations; Allee effects; quantitative models of age- and sex-structured populations with application to conservation and management; predator-prey interactions particularly the effects of changes in relative abundances in multiprey, multipredator systems (e.g. apparent competition, introduction of exotics)
Conservation Biology: conservation planning; quantitative targets for population/species recovery; ecosystem versus species-level conservation
Mammalogy: ecology and evolution of ungulates and carnivores
My field work currently is conducted in western North America & South America (Chilean Patagonia)
