Genetics and Epigenetics in Cancer

Research Interest

My current field of research is on genetics and epigenetics of human cancers and infectious diseases, especially hepatoceullar carcinoma (HCC) and hepatitis B.

Genetic epidemiological study for cancers (e.g. HCC) and infectious diseases (e.g. hepatitis B):

Epigenetic study:

microRNA study:

Study of the HBx gene of HBV in the host genetics and transcriptome.
