Robert J. Bridges, PhD

Professor and Director of Cystic Fibrosis Research

Research Projects

Dr. Bridges' primary area of research is on epithelial ion transport with a special focus on epithelial ion channels. His lab uses a wide range of electrophysiological methods and video imaging to study the regulation, pharmacology and biophysics of ion channels including CFTR, ENaC and various potassium channels. He collaborates with several pharmaceutical companies working toward the development of drugs for the treatment of Cystic Fibrosis and Chronic Obstructive Pulmonary Disease.
