My main expertise is in all aspects of systematics, taxonomy, evolution, and phylogenetics/ phylogenomics of fungi. The most recent focus of my research has been on using systematics, phylogenetics/phylogenomics, genomics, and metabolomics to predict ecological functions and biological activity of fungi found in natural phytobiomes, with emphasis in biological control and sustainable agriculture. I have also delved into investigating the role of fungi in animal microbiomes.
