Research Summary

Developing new diagnostic tools for rapid and early diagnosis of invasive fungal infections. These include identifying fungal pathogens from FFPE tissue blocks, fungal antigen assays, host-driven response assays, multiplex PCR and next-generation sequencing to rapidly identify fungal pathogens directly from clinical samples. I am also interested in studying identification and characterization of new emerging fungal pathogens, the role of fungal pathogens in cystic fibrosis patients, and antifungal drug resistance.
