My research centers on the biology and systematics of fungi, particularly members of the fungus classes Pezizomycetes and the Leotiomycetes, both belonging to ascomycete groups. Using molecular, life history and morphological methods we strive to understand relationships within these groups and to uncover their diversity. In addition, I study the history of collections and collectors.
