Profile
Troy McMullin leads a research programme that is advancing our knowledge of the Canadian lichen biota. He conducts interdisciplinary collection-based studies throughout the country with a focus on regions, habitats and species that are poorly understood.
Troy is 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. The boreal forest and Arctic regions of Canada are his current areas of interest.
