CFTR • chloride secretion • cystic fibrosis • electrophysiology • epithelial transport • fluorescence imaging • ion channel function • ion channel structure

Research Focus

My research focuses on cystic fibrosis and other diseases that affect epithelial tissues. We study the cellular and molecular physiology of transepithelial salt and water transport, explore the regulation of CFTR and other ion channels, examine the cell biology of CFTR, especially its trafficking, and work with partners to develop new therapeutics for cystic fibrosis.
