Clinical Interests

Dr. Harper diagnoses and manages patients with congenital or acquired lung diseases such as asthma, tuberculosis, primary pulmonary hypertension, interstitial lung disease and lung cancer. His research includes the study of oxidative stress in airway epithelial cells and the molecular basis mechanisms of lung cancer development. He is specifically examining signal transduction pathways in response to cigarette smoke. Harper also has a special interest in interstitial lung diseases, including sarcoidosis.
