He got Ph.D degree of Microbiology from Shenyang Institute of Applied Ecology of CAS in 1998. After graduation, he worked as a postdoctoral fellow and then instructor in Cancer Immunobiology Center of UT Southwestern Medical Center at Dallas. He came back to the CAS key lab in 2007 as a scholar of 'Bairen plan' of CAS. Dr. Meng’s current research involves studies of heat shock protein gp96 in innate and acquired immunity, therapeutic vaccine engineering against chronic Hepatitis B Virus (HBV) infection, and cancer targeted therapy.

We currently focus on:
1. Regulation of the immune response against HBV by heat shock protein, and therapeutic vaccine engineering for hepatitis B and cancer therapy
2. Targeted therapeutic approaches against HER2 and uPAR in breast cancer
3. Modulation of HBV replication by MicroRNAs
