Research Interests: 

I'm an evolutionary mycologist who focuses on the systematics, taxonomy, and evolution of ascomycete fungi, particularly those that associate with plants. I use a diverse suite of bioinformatic tools and data derived from molecular ecology and phylogenetics, in conjunction with the Arnold lab's massive culture collection of fungal endophytes. For my dissertation work, I aim to link cutting-edge molecular tools and traditional taxonomic methods to classify and characterize ecologically-significant microscopic fungi that have thus far evaded classification.
