PULMONARY HEALTH

The aim of our research is to understand the relationship between airflows in the lung and respiratory diseases. In particular, we use computational fluid dynamics techniques to simulate patient-specific airflows in healthy lungs and those in diseased lungs with lower-airway obstructions. This approach will provide a foundation for the development of non-invasive tools to diagnose diseases of the lower airways.
