I am a physician scientist with a clinical interest in treating infections in patients with highly compromised immune function. In this patient group, invasive fungal infections are a major infection-related cause of morbidity and mortality.
My laboratory research focuses on opportunistic fungal infections in the lung. Our studies center on host-pathogen interactions between the respiratory immune system and inhaled fungal spores. We are dissecting the molecular and cellular mechanisms that mediate host resistance to the fungal pathogen Aspergillus fumigatus, the most common etiologic agent of invasive aspergillosis.
In the laboratory, host-pathogen interactions are modeled using live fungal cells, mammalian cell lines, primary cell cultures, and transgenic or knockout mice with defined genetic alterations. Interactions between fungal and mammalian cells or intact mice are analyzed and quantitated using microscopic, flow cytometric, proteomic, and other standard methods in molecular biology, cell biology, and immunology.
Research in the laboratory targets the following areas.
1. The dynamic role of monocytes and derivative cells in the induction of respiratory innate and CD4 T cell responses against Aspergillus spores.
2. The contribution of resident and recruited leukocyte subsets and the alveolar epithelium in the generation of inflammation following respiratory fungal challenge.
3. The requirement for specific innate immune signaling pathways (TLRs, dectin) in the cell stage-specific recognition of Aspergillus and the calibration of inflammation.
4. Immunomodulatory effects of antifungal therapies.
