Program Interests
Research in my lab focuses on the molecular evolutionary genetics of fungi, mostly in the realm of molecular phylogenetics and systematics at the species level. We apply these tools mostly to identify and better understand the fungal culprits in plant and animal diseases and toxicoses. Unfortunately, identifying fungi using traditional micromorphological tools is very difficult, and tends to lead to species concepts that are too broad. We use the tools of multilocus molecular phylogenetics to recognize and identify species, which provides a much more objective and reliable framework for understanding the biology of these fungi.

As Director of the Fusarium Research Center at Penn State, I also curate the world's largest collection of cultures of Fusarium, one of the most important genera of toxigenic and pathogenic fungi. We are nearing 20,000 accessions and provide isolates to certified researchers, and also provide identification and other services. Most of the research in my lab naturally involves this important genus, but I am also involved in projects in a variety of other fungi.
