Research interests

  • Population dynamics and behavioural ecology
  • Predation, parasitism and herbivory
  • Conservation biology and wildlife management

My research mostly focuses on quantifying responses of individuals and populations to factors such as predation, parasitism, or habitat loss; my students and I work in natural, experimental and managed systems, mainly on mammals and amphibians.  I am also interested in the development of models and other tools for the conservation and management of populations or species.

Current Projects in my lab

  • Population viability analysis for a recovering red wolf population
  • Physiological and behavioural indices of mortality risk snowshoe hares
  • Amphibian responses to perceived predation risk
  • Population ecology of wolves in protected (and non-protected) areas
  • Density dependence in waterfowl populations
  • Moose population dynamics relative to habitat and climate change
     

Information for prospective students

I seek highly motivated and industrious students that are more question- than species-driven.  Prospective students should have good academic standing, a solid understanding of ecological principles and theory, superior field and quantitative skills, and an insatiable curiosity about natural systems.
