Current Research

My research program is focused on advancing our knowledge of the Canadian lichen biota. I conduct interdisciplinary collection-based studies throughout the country with a focus on regions, habitats, and species that are poorly understood. I am attempting to resolve unknown questions in lichen ecology, developing regional base-line data for areas with knowledge gaps, and addressing taxonomic uncertainties using morphometrics, metabolite determinations, and phylogenetic analyses. Using the results from my research I help to develop conservation strategies for rare lichens and rare habitats. My current areas of interest are the Arctic, Atlantic Provinces, and National Parks.
