Research
Interests
For many years my research focused on the systematics and evolution of fungi that form symbiotic lichen associations with algae. In particular, my research examined the reindeer lichens in the family Cladoniaceae using molecular-genetic data to examine either the independent origins of the lichen habit in the fungi, the phylogenetic relationships among and within lichen-forming fungi, or the variation within species and natural populations. Through comparison of the phylogenetic relationships of lichen-forming fungi with those of their algal partners, my laboratory group examined cospeciation and algal switching among lichen associations. More recently, I have expanded this research to study reindeer lichens in the reindeer herding regions of northern Mongolia as part of a multi-disciplinary project. My research uses lichens and plants to document the health and herding capacity of pasture lands and explores the uses of lichens and plants by traditional Dukha/Tuvan herders.
