His research focuses in three main areas. First: Biology and pathogenesis of CF and new treatments. Second: Physiology and cell biology of airway epithelia. Third: Acid sensing ion channels in the central and peripheral nervous systems with an emphasis on their role in fear and neurological diseases. Contents ? Background ? Materials and Methods ?
