Current Research Interests

  Research in my lab focuses on population ecology and dynamics of insects in a spatial or landscape perspective. Projects examine both the large-scale pattern of population change, and the mechanism by which landscape alters the processes which drive those dynamics.

Our current projects include

The effect of forest fragmentation on forest tent caterpillar, its parasitoids and viral disease.
The effect of meadow size and isolation on dispersal and dynamics of alpine Parnassius butterflies.
The effect of habitat structure on willow cone-gall midge and its parasitoids.

The effect of habitat fragmentation and invasive weeds on butterflies of Garry Oak meadows.
