Research Interests
My research focuses on the ecology of lichens and mycorrhizal fungi. I am interested in understanding (1) how plant succession influences ground lichen composition, growth, and survival and (2) how lichens can serve as indicators of airborne metal pollution. Given continuing urbanization in the Mid-Atlantic region, I am especially interested in questions related to anthropogenic impacts on lichens. Recent student research projects have examined growth dynamics in terricolous lichens in the New Jersey Pine Barrens and metal pollution indication by corticolous lichens in the Delaware Valley urban landscape. Relatedly, I teach Conservation Biology, Mycology, Plant Communities, and the Ecology of Northern California (taught in San Francisco in summers).
