Research Interest
Chronic diseases such as cancer, obesity and diabetes are the leading causes of death and disability in the United States. My researches have been focusing on the prevention of chronic diseases using strategies of gene expression/deletion or functional compounds present in human diet, phytochemicals, and drugs. In addition, we identified several genes have anti-tumorigenic and obesity-suppressing activities. Currently, my lab is focusing on two main areas. The first area is chemoprevention and molecular carcinogenesis of human cancer. The overall goal of this direction aims to identify new effective chemopreventive agents/human cancer susceptibility genes and elucidate their mechanisms of action using in vitro cell culture and rodent cancer models. The second area of research aims to prevention of metabolic syndrome through basic and preclinical studies.
