Resume:

Infectious diseases are major health threats throughout the world. The main function of our immune system is to fight viral and bacteria invasions. Innate immunity is the first line for defense against microbial infections. In my lab, we are interested in understanding the molecular mechanisms of antiviral innate immunity by using different model systems such as mouse and fly. Meanwhile, we are also interested in the regulatory mechanisms underlying the fate determination of stem cells.

Research Interests:

Antiviral innate immunity; Stem cell biology.
