Research

Dr. Chang is currently working in collaboration with Dr. David Beer studying the pathogenesis of esophageal cancer. His particular interest is in studying the progression of disease from dysplasia in Barrett's esophagitis to the development of esophageal adenocarcinoma, utilizing microarray analysis and validation in order to identify potential targets for therapy and/or chemoprevention.

Clinical projects under development, in conjunction with the Geriatrics Center, include studies aimed at assessing outcomes after thoracic surgery among elderly patients and devising intervention strategies that will improve the surgical care and resident education of geriatric patients. Efforts are additionally underway to develop specialized computer-based training tools that will facilitate the teaching, assessment, and performance of advanced thoracoscopic surgery.
