My research bridges fungal taxonomy and proteomics to explore microbial diversity and host–pathogen interactions. In taxonomy, I investigate Basidiomycota fungi across Brazilian ecosystems, describing new species and clarifying evolutionary relationships to advance understanding of fungal biodiversity. In proteomics, I apply mass spectrometry to study antimicrobial resistance and host–pathogen dynamics, identifying molecular mechanisms of pathogenicity and informing innovative approaches for infection detection, treatment, and ecological applications.
