Meng is a professor of Tsinghua University, Beijing, China. He obtained his bachelor degree in 1983 at Southwestern Agricultural University, China, and PhD in 1991 at Nottingham University, UK. He was director of the Institute of Zoology, Chinese Academy of Sciences (CAS) (2008-2012). He is an elected fellow of CAS. He has been working mainly on maternal factors related to regulation of cell lineage, body axis determination, and germ layer formation and patterning using zebrafish and mouse models. His representative work include: 1) revealing the role of Dpr2/Dact2 in mesoderm induction by antagonizing Nodal signaling (Science, 2004); 2) discovery of the maternal factor Huluwa as the key organizer determinant in the zebrafish embryo (Science, 2018); 3) Discovery of the second polar body's role in preimplantation cell fate determination and postimplantation development of the mouse embryo (National Science Reviews, 2022); 4) demonstration of regulation of zygotic genome activation by maturity of nuclear pole complexes in the zebrafish (Cell, 2022).
