Research Interests

• Mechanisms of carcinogenesis and its prevention, including characterization of the molecular alterations during different stages of human esophageal carcinogenesis
• Development of animal models for esophageal adenocarcinomas and colitis-associated colon cancer for mechanistic and prevention studies
• And mechanisms of inhibition of carcinogenesis by tea and its constituents including tumorigenesis studies in animal models, molecular investigation with cell lines, pharmacokinetics and bioavailability studies in animals and humans, and human intervention studies.
