Prof David CL Lam is a respiratory physician with interest in translational research and clinical trials in respiratory diseases including lung cancer, smoking and airway physiology, COPD and interventional pulmonology. His research focuses on translational research with biomarkers in lung cancer and airway.

In his research laboratory, new lung cancer organoids and immortalized normal bronchial epithelial cell lines representing local Chinese population are established and characterized, and they are being used as cellular models for translational research on lung cancer, smoking and airway physiology research. Plasma EGFR mutations and circulating tumor markers are studied.

He also performs bronchoscopy including endobronchial ultrasonography and autofluorescence imaging. He is currently in the International Lung Screening Trial (ILST) Consortium, steering lung screening and relevant biomaker research.
