Research

    Overview of research:
    The main study of mine is the PKU-beta/TLK1 that is related to the cell cycle progression, espacially mitosis. It is being done by the means and the views of cell biology, biochemistry and molecular biology. In addition, the mechanism of phenomena that PKU-beta/TLK1 contributes to DNA repair is also studyed.
