Research Interests
Microbial Ecology and Evolution: The Lichen as a Microcosm
As a member of the Lutzoni lab, I am researching lichen-associated (non-photobiont) bacteria. There is an ever-increasing body of evidence suggesting that lichens exist not simply as dual partnerships, but as microcosms comprised of diverse assemblages of specific microbial lineages. Through my research I have detected an undescribed lineage of bacteria ('LAR1') that has been found almost exclusively in association with lichens. As part of this research I am continuing to develop tools (e.g., primers, protocols, and techniques) that can be widely applied to the study of microbial ecology and evolution in environmental settings.

Systematics of Lichens and Lichenicolous Fungi
Taxonomic problems abound in the realm of lichenology. I use molecular phylogenetic techniques in concert with traditional analytical methods in order to illuminate the evolutionary histories of specific lineages. Taxonomic changes are made only when the current system is found to be untenable for a given set of organisms. This work has provided much insight into which outward characteristics are best for revealing evolutionary relationships. Over the past several years, I have also assembled the first checklist of lichens and lichenicolous fungi for Virginia, USA, containing over 600 taxa. All reports are specimen-based and are carefully evaluated and verified. Through this type of research, we have been able to gain a much better understanding of the overall diversity of lichens and lichenicolous fungi.
