Education:

BSc, Nipissing University;
MSc, Laurentian University;
PhD, University of Western Ontario

Areas of Specialization:

Forest ecology; community ecology; dendrochronology; ecological modeling; silviculture.

Research Interests:

Growth and yield modeling, predictive habitat modeling of understorey species, forest disturbance and stand dynamics; forest productivity and ecological land classification; prediction of wood quality attributes; community dynamics; Boreal and Great Lakes – St. Lawrence forests.

Current & Future Research:

  • Capturing site effects in boreal forest growth and yield models at the ecosite-level.
  • Diversity and stability relationships in dry forests of the Great Lakes – St. Lawrence Forest Region.
  • Distribution, abundance and regeneration of Canada Yew (Taxus canadensis) in the Boreal and Great Lakes – St Lawrence forests.
  • Black Ash stand dynamics and regeneration in the Great Lakes - St. Lawrence forest region.
  • Predictive modeling of wood fibre attributes in boreal species based on ecological site classification and other forest inventory variables.
