Board Certified in Obstetrics and Gynecology from The American Board of Obstetrics and Gynecology Inc.

Dr. Zhang is an early pioneer of Minimal Stimulation IVF & Natural Cycle IVF; Embryo & Egg Freezing Freezing by Vitrification; and Cytoplasmic Transfer.

After completing his medical degree at the Zhejiang University School of Medicine in China in 1984, Dr. Zhang undertook postgraduate training in the United Kingdom. He studied male infertility at Birmingham University, earning a Master's Degree at that institution in 1985. He was one of 80 overseas student recipients of the British Postgraduate Scholarship in 1989.

At Cambridge University, Dr. Zhang studied in vitro maturation and fertilization of mammalian oocytes, earning a Ph.D. in In-Vitro Fertilization (IVF) in 1991. In 1997, after more than 10 years of training and research in the biology of mammalian reproduction and human embryology, Dr. Zhang pursued and successfully completed a residency in the Department of Obstetrics and Gynecology at the New York University School of Medicine. In 2001, Dr. Zhang was chosen to become the first Fellow in the Division of Reproductive Endocrinology and Infertility of New York University School of Medicine.

Dr. Zhang founded the New Hope Fertility Center in 2004. Because of his research and clinical work in mammalian in vitro fertilization he is recognized as a world leader in gentler assisted reproductive technology (ART) including minimal stimulation IVF (the Mini-IVF^TM treatment) and natural cycle IVF, and his participation is widely sought in international conferences. His major research interests are oocyte reconstruction by nuclear transfer, and long term cryopreservation of oocytes, embryos and ovarian tissue. He is one of a handful of reproductive endocrinologists in the U.S. who also holds a Ph.D. in embryology with an additional certification as high complexity laboratory director.
