Brief biography

I am a fungal biologist interested in fungi in nature (especially mushrooms) and medically-relevant fungi. I use several kinds of genetic data, including genomics, transcriptomics, and DNA barcoding, to study the biology of these organisms. I have had the opportunity to conduct fieldwork in Australia, China, Costa Rica, French Polynesia, Guatemala, Mexico, Svalbard, Thailand, Canada, and the United States, in tropical, temperate, arctic, and alpine biomes. I am also very interested in bioinformatics and computational biology, especially the analysis of high-throughput ("next-gen") sequence data for genomics, population genetics, biodiversity research, microbiome diversity, and transcriptomics (gene expression studies); these interests have provided me with the opportunity to collaborate with researchers at UWL and elsewhere on organisms including insects, fish, soil microbes, aquatic microbes, and mollusks.

Some of the areas of current research in my lab include understanding the invasion history of the cultivated golden oyster mushroom (Pleurotus citrinopileatus), species discovery and phylogenetics in the bolete genus Tylopilus, understanding the biology of post-fire morel mushrooms (genus Morchella), characterizing Driftless area fungal biodiversity, and studies of alpine fungi.
