  • Fungal infections are increasing, and with the expanding use of new and established antifungal agents, antifungal resistance has become an important clinical problem. One of my research interests is to develop and standardize antifungal drug combination testing methods using traditional microbroth dilution and probe-based methods, with an ultimate goal to introduce these assays to routine clinical laboratory testing with short turnaround time. The second focus area is special investigations on clinical diagnoses such as fungal identification from paraffin-embedded tissues and other non-cultivable, non-viable specimens; real-time PCR assays on primary fungal pathogens including Coccidioides immitis/posadasii, Histoplasma capsulatum,Blastomyces dermatitidis, and Cryptococcus gattii/neoformans. The third area of my research interests is diagnostic method development and evaluation on any new emergent infectious organisms and infectious diseases.
