Research Interest:

Prokaryotes are threatened by viral invasion and armed with diverse immune systems, such as CRISPR-Cas, to defeat virus. We want to(1) understand how the immune systems degrade viral DNA and/or RNA to protect host, (2) reveal how the immune systems affect the competition between host and virus, (3) identify tool enzymes from prokaryotic immune systems.
