Biography

Dr. Chang’s clinical research focuses on development of endoscopic modalities for cancer diagnosis, staging and therapy. He has pioneered the development of Endoscopic Ultrasound (EUS)-guided FNA, and subsequently, EUS-guided FNI (fine needle injection) and has written more than 200 publications and book chapters regarding its utility in GI malignancies. He also holds several patents in his development of new endoscopic technologies.

Dr. Chang is also on the editorial board of several journals in gastroenterology. His clinical expertise in pancreatico-biliary endoscopy includes EUS, EUS-guided FNA, EUS-guided Intervention (celiac ganglion neurolysis, anti-tumor agents, choledochoduodenostomy, etc), and endoscopic retrograde cholangiopancreatography (ERCP). For esophageal and gastric interventions, his expertise includes endoscopic treatment of gastroesophageal reflux disease (GERD), as well as photodynamic, laser, cryo, and radiofrequency ablation therapy for Barrett’s and esophageal cancer.
