Current Research

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:

• Mitochondrial regulation of lung immunity
• Immune interactions of alveolar macrophages in situ
• Lung mechanobiology of the actin fence
• Platelet-neutrophil interactions in immunity
• Protein transduction in therapy for lung injury
