Nicholas M. Fisk (born 1956) is an Australian maternal-fetal medicine specialist, academic and higher education lead. As a researcher, his group has pioneered advances in understanding fetoplacental disease and its treatment, including characterising early human fetal stem cell populations and their lifelong persistence in maternal tissues, documenting “fetal pain” and its blockade by opioid analgesia, and unravelling the vascular basis of twin-to-twin transfusion syndrome. As an obstetrician, Fisk is known for inventing the natural caesarean operation, also referred to as the family centred caesarean section. In 2016 he was appointed as Deputy Vice-Chancellor (Research & Enterprise) at the University of New South Wales (UNSW Sydney). Source: Wikipedia (en)
