Areas of research focus

  • Palynology and paleoecology
  • Late Quaternary vegetation dynamics of western North America
  • Wetland succession and peatland carbon accumulation
  • Temperate rainforest ecology
  • Life history theory and biogeography
  • Multivariate statistics

My main area of research is the development and dynamics of temperate forest in coastal British Columbia since the last glaciation. This research concerns temporal and spatial patterns in the distribution of plant populations and communities, and the processes responsible for those patterns.

I conduct research that:

  1. reconstructs the development and dynamics of plant populations and communities, using techniques such as high-resolution pollen analysis of radiocarbon-dated lake sediment and peat, and
  2. identifies the ecological (e.g., life history) and environmental (e.g., climate change) factors that drive species abundance, species interactions, and community distributions.

Recent research in my lab has focussed on wetland development and succession, and links between peatland carbon accumulation and past climate change.
