Research
Investigations in my laboratory focus on understanding mechanisms and regulation of electrolyte transport across epithelial tissues and on innate immune function of the airway epithelium in relation to cystic fibrosis, asthma and allergic airway disease. Cultured human airway epithelial cells are currently used to study regulation of ion transport and cell migration by a variety of signaling molecules. A combination of electrophysiological approaches and molecular techniques provide a means of identifying transport mechanisms and signaling pathways that are important in controlling salt and fluid movement across the airway epithelium. Studies of innate immune function are being conducted in collaboration with Dr. Hirohito Kita from the Mayo Clinic. These studies address the role of the airway epithelium in allergic inflammation induced by environmental allergens and fungal infection of the lung.
