We use physics-based mathematical models to simulate airflow, blood flow and gas transfer within the human pulmonary system. These models are simulated upon patient-based virtual lung and vascular structures, generated from computed tomography scans. Models have been validated experimentally (using 3D printed lungs) and clinically.
We use these models to analyse how structural changes to pulmonary morphology generates ventilation heterogeneity, affects oxygen delivery, and alters patient quality of life. We also use these models to better quantify how different types of lung disease are reflected in pulmonary function test outputs. Below are some key publications in this theme (click image to access paper). A full list of publications can be found here.
