Research Summary

Our laboratory is located in the research complex of the UCSD Hillcrest Hospital in San Diego. We focus on the basic defects and malfunctions associated with the fatal, hereditary disease cystic fibrosis (CF). Biomedical research activity on CF has exploded during the past decade such that virtually all areas of medical science have been brought to bear in this disease. Our expertise is in fluid and electrolyte transport which means that we largely use electrophysiological techniques to explore these problems; we also employ ratiometric fluorescence, immunocytochemical and molecular biology approaches as well. We generally investigate freshly isolated human tissues. Current areas of investigation include: G-protein control of ion channels, the composition and control of human airway fluids, and processes controlling HCO3- movements through the anion channel affected in cystic fibrosis, CFTR.
