Dr. Kenneth Hallows' main research interests are in epithelial ion transport physiology and the coupling of membrane transport processes to cellular metabolism via the metabolic sensor AMP-activated protein kinase (AMPK). Current research projects involve elucidating the mechanisms of epithelial Na+ channel (ENaC) and cystic fibrosis transmembrane conductance regulator (CFTR) regulation by AMPK in kidney and lung epithelia and characterizing the mechanism of altered AMPK regulation and activity in the cystic fibrosis airway and its beneficial role in mitigating the excessive CF inflammatory response.
