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.

Over the past 10 years, our major research contributions include: (i) the discovery of the role of angiogenesis for normal lung development and repair; (ii) the demonstration of the therapeutic potential of stem cells in experimental bronchopulmonary dysplasia (the chronic lung disease of prematurity), asthma, acute lung injury and pulmonary hypertension; and more recently, (iii) the therapeutic potential of adeno-associated virus (AAV)-mediated gene therapy for surfactant protein deficiency.

We are now translating innovative cell and gene therapies from the lab into patients to improve outcomes.
