What We Do

Our lab is focused on understanding the mechanisms of lung development, injury and repair in order to design new treatments for incurable lung diseases. We have an ambitious research program set out to study clinically relevant questions in the lab for translation into real-life applications. All animal models of human lung disease are available in our lab, and we correlate structural and functional changes to assess the clinical relevance of the experimental therapies we are testing.

Our major research contributions over the past seven years include (i) the discovery of the role of angiogenesis in normal lung development and repair, and (ii) the demonstration of the therapeutic potential of stem cells in experimental bronchopulmonary dysplasia, asthma, chronic obstructive pulmonary disease, and pulmonary hypertension.

Over the next five years, our goal is to bring safe and effective cell-based therapies for lung diseases into the clinic, and thereby create vast improvements in patient outcomes.
