Research Interests:
To investigate the functions of several protein kinases in the regulation of cell cycle progression and cell death, in the response to environmental factors, as well as in the cellular sensitivity to anticancer drugs, using a single-cell eukaryotic organism, fission yeast Schizosaccharomyces pombe as an in vivo model.

Thesis Topics:
1. Cell signaling for the interplay between cell-division cycle and gene expression events such as pre-mRNA processing, mRNA export, as well as heterochromatic silencing in eukaryotes involving several protein kinases including Dsk1 and Kic1. 2. Genomic studies on genes involved in the cellular sensitivity and resistance to platinum-based anticancer drugs 3. Genomic studies on conserved response networks to phenol derivatives as environmental stress factors
