Research

My forest-related research focusses on the development and dynamics of temperate forest in coastal British Columbia over the past 15,000 years i.e., 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 past changes in forest composition and fire frequency, using techniques such as high-resolution pollen and charcoal analyses of radiocarbon-dated lake sediments, and 2) identifies the ecological (e.g., life history) and environmental (e.g., climate change) factors that drive changes in species abundance, species interactions, community distributions, and disturbance regimes on long ecological timescales.
