Research Focus

Lung stem/progenitor cell biology and defining mechanisms of normal tissue maintenance, repair and remodeling in disease. My laboratory is particularly interested in understanding epithelial defects that contribute to the development of fibrotic lung disease and identifying new therapeutic approaches to help patients afflicted with these lung disorders.

Research Contributions

Leader in the field of lung epithelial stem cell biology.

Current investigations include:

Our basic research focuses on defining cellular and molecular mechanisms of normal tissue maintenance and repair following injury. We use genetically modified mouse models for lineage tracing and to manipulate cell signaling in the normal and repairing epithelium. We have established culture methods for growth of single cell-derived lung organoids from mouse and human lung to model disease and for drug discovery.
