My visiting research at the University of Iowa focuses on Amphotericin B, a polyene compound that has recently been shown to improve airway surface liquid in cystic fibrosis individuals. I am collaborating with Dr. Michael Welsh, to understand the mechanisms by which amphotericin B enhances anion secretion in the cystic fibrosis airway. To this end, we utilize electrophysical techniques to elucidate these mechanisms in human airway epithelial cells.
