Research Interests

Mechanisms governing genome stability

Research Summary

The overall goal of research in my lab is to understand the mechanisms governing genome stability, and more importantly, how we can apply new knowledge to prevent genome instability as well as to fight against cancer and aging-related diseases. We are carrying out three areas of research in parallel: a) maintenance of the stability of fragile sites in the genome in response to environmental genotoxins, b) maintenance of telomere integrity, and c) translational research. We apply innovative approaches including next-generation sequencing, advanced fluorescent microscopy, and genome editing to accomplish our research goals.
