Research Interest Lung image analysis.

Development and validation of computer algorithms to improve quantitative assessment of structural changes of the lung depicted on CT examinations.

Investigate the association between pulmonary disease and structural changes of the lung for variety of diseases such as COPD, asthma, interstitial lung disease, and lung cancer.

Classify subjects based on structural changes of the lung that are responsible for functional abnormalities and predict the likelihood of rapid disease progression (i.e., risk).
