I assumed my present appointment in 2014 and currently share responsibility for the provision of specialist for medical gastroenterological services in the Seoul National University Hospital. These include the full range of diagnostic procedures, clinics including chemotherapy and consultations appropriate to a large teaching hospital. I have had particular responsibility for biliary and pancreatic diseases. I have performed the clinical and translational study for biliary and pancreatic diseases. I am trying to develop the new type stents for the intervention and new therapeutic agent for the pancreato-biliary malignancy.
