Hui Liu, MD, PH.D., MSC

Chief Scientist

Doctor Hui Liu is an internationally recognized Reproductive Scientist and Embryologist. He serves as the Chief Scientist and Senior Embryologist to New Hope Fertility, contributing significantly to the development of human nuclear transfer techniques including germinal vesicle (GV) transfer, metaphase II (MII) spindle transfer and pronuclear transfer. 

Doctor Liu graduated from Xi’an Medical College (now Xi’an Jiao-tong University School of Medicine) in 1985 and was a practicing physician for two years. He received his master’s degree from the College of Life Science in Beijing Agriculture University (China Agriculture University), after which, he investigated gamete maturation and fertilization (activation) and embryo development in mice, guinea pigs, rabbits, and giant pandas from 1990 to 1998, becoming an Associate Researcher at State Key Laboratory of Reproductive Biology, Institute of Zoology of Chinese Academy Sciences.

As a Research Scientist at the New York University Program for In Vitro Fertilization, Reproductive Surgery and Infertility from 1998 to 2008, Hui Liu developed nuclear transfer techniques and his works were recognized and awarded by ASRM in 1999 and 2000. He then joined New Hope Fertility Center as a Senior Research Scientist, where he continues to develop the technique of nuclear transfer for human reproduction and has established a reliable system for the transfer of human oocyte GV and MII spindle and found direct evidence of the safety of human MII spindle transfer, leading the birth of first healthy baby by applying MII spindle transfer for patient to prevent transmission of maternal inherited mitochondrial disease. 

As a Senior Embryologist at New Hope Fertility Center, Hui Liu has introduced multiple techniques in routine IVF practice, including spindle view to evaluate oocyte maturity and quality guiding the right way to care each oocyte specifically, laser-assisted ICSI to enhance the chance of normal fertilization, assisted activation to rescue incompetent oocytes, evaluate early events of fertilized egg cultured in EmbryoScope to predict the potential of embryonic development. Optimize the cryopreservation protocol for human oocyte, especially for oocyte at GV stage, a potential application to allow the GV of aged women to complete normal meiosis in healthy cytoplasm. 

Message from Hui Liu

“Life is miracle, start from embryos, start from fertilized oocytes, each individual oocyte is unique, to care the unique each individual oocyte and embryo with wisdom, knowledge and full skills, the miracle will come to true.”
