Current Projects

Heavy metals in Callahan Mine seaweeds. Dr. Nishanta Rajakaruna, Dr. Arthur C. Mathieson, and I are currently wrapping up a manuscript about metal accumulation and seaweed diversity at Callahan Mine, an intertidal Superfund site and one of our coastal Maine geoecology field sites. I’m also finishing up a survey of the Mosses of Callahan Mine, completing our inventory of the terrestrial vegetation at that site.

Lichens of South Africa. This past February, Dr. Alan Fryday, Dr. Nishanta Rajakaruna, Dr. Stephan Siebert, Arnold Frisby, and I collected saxicolous lichens in Mpumalanga and Northern Cape provinces of South Africa for a National Geographic Society-funded project looking at trends in lichen diversity and abundance on different rock types along a rainfall gradient. We are currently identifying the many lichen samples collected during this trip. Because there are many gaps in our knowledge of South Africa’s lichens, this ecological project also involves a fair amount of first-order taxonomic work.

Evolution and taxonomy of Graphidaceae. Under the supervision of Dr. Robert Lücking and Dr. Thorsten Lumbsch, I’m working on a few different projects with lichens of the family Graphidaceae: putting together phylogenetic trees, describing new species, and compiling a monograph for one of the tribes of this very large family. This work began with my REU at the Field Museum in 2014.

Ecology of serpentinite outcrops in Massachusetts. My senior thesis research at College of the Atlantic was concerned with the plants, lichens, and bryophytes of adjacent serpentinite, amphibolite, and schist outcrops in western Massachusetts. I am still analyzing data collected during this project and working to turn my thesis into a manuscript for publication
