Lab Director, Chief Embryologist

Dr. Li is a certified High-Complexity Laboratory Director (HCLD) in the discipline of molecular diagnostics, with extensive experience in the field of genetics and molecular biology and is also a certified High-Complexity Laboratory Director (HCLD) in the discipline of embryology and andrology. She holds a New York State PGD (molecular) director certificate.Her research on timely aneuploidy screening has profoundly impacted biopsy timing in the field of IVF-PGT-A. Her team’s work revealed that aneuploidy screening at the cleavage stage did not accurately predict the chromosomal constitution of blastocyst, leading to the development of methods for screening embryos at this later stage.
She is a nationally renowned embryologist and well-respected expert in ICSI and preimplantation genetic diagnosis. Dr. Li has been teaching embryo biopsy since 2003, formerly through national course offerings with ART Reproductive Center, Inc., and served as the director of PGD Science, Inc. before she assumed her leadership role atPacGenomics. Dr. Li was trained in the Reproductive Medicine Center of the Zhongshan University Medical School in China, and received her M.D. in 1990 and her PhD in 1998. Dr. Li was a fully licensed physician specializing in reproductive endocrinology in China before she immigrated to the US on an EB-1 visa as an “outstanding scientist.” She was among the first REI physician scientists performing ICSI (as early as 1994) in China.
