My research interests are in the general area of
solute and water transport across epithelial membranes in the
lung. Epithelial cells in lung airways and alveoli are normally
attached very tightly to one another and provide a substantial
barrier to the movement of solutes and water into or out of the
airspaces of the lung. In lungs injured by disease or external
agents, however, these barriers can become "leaky" and
their transport functions, as well as lung function in general,
may be compromised. We have developed a variety of techniques
to study transport mechanisms in the lung, how those mechanisms
are controlled, the effect of lung injury on epithelial transport
processes, and recovery of those processes following lung injury.
I currently collaborate with colleagues in the Departments of
Medicine and Pediatrics on two studies: stimulation of fluid resorption
across the rat alveolar epithelium and mechanisms of toxin-induced
injury to the airway epithelium.
