Peter Leung is a highly accomplished scientist known internationally for innovative research. He pioneered the cloning and characterization in humans of a key regular of the reproductive system, the gonadotropin-releasing hormone (GnRH) receptor. He developed the concept of a multi-faceted role of GnRH across the reproductive axis, which challenged and revolutionalized the field. His numerous original research publications have been highly cited and he is the author of authoritative reference texts on ovarian biology. Dr. Leung’s innovative discoveries in multiple areas of reproductive biology and medicine have significantly contributed to our understanding pathophysiological issues in women’s reproductive health.
