About LA IVF


Li Meng, PhD, HCLD
Laboratory and Scientific Director

Dr. Li Meng earned his Ph.D. degree in reproductive physiology, and obtained his postdoctoral training in University of Western Ontario, Canada and Oregon National Primate Research Center (ONPRC). Using rodent and nonhuman primate models, Dr. Meng’s research focused on the nucleocytoplasmic interaction during oocyte maturation and preimplantation embryo development in human and non-human primates. Dr. Meng successfully cloned the world’s first primate, Rhesus, in 1997 at ONPRC. In 1998, Dr. Meng started his first clinical IVF Laboratory directorship at Brown University. Dr. Meng is also a two-time recipient of the American Society for Reproductive Medicine (ASRM) General Program Prize which highlights the importance of (1) Germinal Vesicle transfer in human oocytes and (2) the SpindleView Imaging System for non-invasive observation of living cell spindles. Dr. Meng also obtained research funding for the Andrew W. Mellon Foundation, EMD Serono Inc., and NIH-SF 424 (R&R). Recently, Dr. Meng collaborated with Nikon and developed the BioStation CT system, a cell culture synchronization observation system that integrates cell intelligence (AI) culture, remote observation, imaging, and data processing. The system has been applied in embryonic fields, drug screening, embryonic and adult tissue stem cells, and tissue regeneration.
