Research Interests

  • Elucidation of the genetic and epigenetic basis of major gastrointestinal (GI) cancers (i.e. gastric, colorectal and liver cancers) and functional validation of key molecular abnormalities
  • Molecular characterization of fecal microbiota in nonalcoholic steatohepatitis and colorectal cancer
  • Identification and large-cohort validation of new diagnostic and prognostic biomarkers for GI cancers
  • Identification of novel therapeutic targets and development of new molecular therapies for GI cancers
  • Clinical trials for viral hepatitis B and C treatment
  • Development of non-invasive tests for diagnosis and prognostication of liver diseases
  • Study of ketamine-induced liver injury
  • Development of novel endoscopic techniques for GI cancer screening and treatment
  • Epidemiological and epigenomics studies of inflammatory bowel diseases
  • Evaluation of the functional role of autophagy in digestive diseases
  • Biomarkers of functional gastrointestinal disorders
