We are interested in understanding how innate immune responses regulate lung health. Innate immunity involves ancient, and well-conserved mediators and their actions regulate the balance between homeostasis and pathogenesis. In the lungs, innate immunity play a critical role in response to environmental exposures such as allergen and ambient particulate matter. My lab focuses on how these exposures can promote aberrant mucosal responses that can drive the development of diseases like asthma.

The mission of the Johns Hopkins University Dermatology, Allergy and Clinical Immunology (DACI) Reference Laboratory is to provide comprehensive, high-quality diagnostic allergy and immunology testing to patients throughout North America with asthma, allergy and immunologic disorders. We offer an extensive menu of laboratory tests that includes allergen-specific IgE measurements to approximately 300 pollen, epidermal, mold spore, mite, food, drug, venom and occupational allergen specificities. We specialize in Hymenoptera (insect sting) venom-specific IgE and IgG antibody measurements. In addition, the DACI Laboratory performs hypersensitivity pneumonitis precipitin panels, serum cotinine, and environmental mold measurements.

The Gregory Diette Laboratory studies the epidemiology of lung diseases. Our focus is on asthma, chronic obstructive pulmonary disease (COPD) and environmental causes of lung disease, including allergens and particulate matter.
