Biodiversity, systematics, and molecular phylogenetics / evolution of fungi important in agroecosystems and tropical forests.
My primary research interests are in the systematics (taxonomy) and biodiversity of ascomycetous fungi. Until now, I have focused my work on the order Hypocreales (Ascomycota), more specifically, with fungi that have biocontrol properties against plant pests and diseases. Currently, I also have research projects that deal with the taxonomy of endophytes in the tropics and the systematics of fungal pathogens associated with hardwood trees in temperate regions. In my research, I use a synergy of traditional taxonomic techniques, such as field collecting, microscopy and culture in artificial media, as well as modern tools, such as molecular phylogenetic analyses using DNA sequences from multiple genes.
