CURRENT RESEARCH ENDOTHELIAL MECHANISMS OF LUNG INJURY USING CULTURED CELLS AND THE OPTICALLY IMAGED LUNG. The Lung Biology Laboratory specializes in single and two-photon laser scanning microscopy of the intact lung. The overall direction is to apply real-time imaging in understanding molecular mechanisms underlying lung injury. Ongoing projects are:
