Research Interests:

The primary interest of my research is to elucidate the mechanisms involved in regulating ion transport, volume flux, and muscociliary transport in both normal and diseased (e.g. cystic fibrosis) airway epithelia. My research is currently focused on a number of key areas, including:

  1. Elucidating the mechanism(s) of ATP release (transport, conduction, and/or exocytosis) in human airway epithelia
  2. Elucidating the role of cell membrane (including the lipid bilayer and actin cytoskeleton) in mechanotransduction
  3. Development of ultra0sensitive, avalanche photodiode-based, luminescence system for quantifying changes in extracellular ATP in isolated tissues
  4. Development of a system to elicit complex, high-frequency, forces on isolated tissue
  5. Measuring adenosine nucleotides/nucleotides and other metabolites in very dilute solutions using mass spectrometry and NMR
  6. In Vivo Imaging of mucociliary clearance by technetium-99m scintilography in anesthetized mice
  7. Development of a system to collect exhaled breath condensates from mice undergoing oscillatory shear stress
  8. Identification of serum biomarkers for CF, suitable for surrogate markers of lung function, using mass spectrometry
