I am a biogeographer specializing in plant dispersal, migration and disturbance ecology in temperate forests and alpine ecosystems, with research in Ontario, BC and the Karakoram-Himalaya. I am interested in human impacts associated with ecosystem fragmentation, altered disturbance regimes, introduced invasive species and climate change, and how to manage these impacts. I also research and develop digital tools for experiential field learning, including virtual and augmented reality tours of alpine, forest and other ecosystems that bring the field to the student (virtual reality) or the student to the field (augmented reality) and complement my own ecological research.
