"My ISUOG membership over the past decade has empowered me to establish SANA Medical NGO in North Lebanon, modelled on ISUOG Outreach. This has been a most gratifying experience: spreading ISUOG's teachings and providing training to midwives and nurses in our neediest underserved areas. Our trainees are now enabled to provide comprehensive antenatal care, positively impacting the lives of under-resourced Lebanese mothers as well as Syrian refugees."

"I am committed to supporting ISUOG’s membership growth and providing educational opportunities in underrepresented regions of the world. I have contributed to the Society’s scientific program, speaking at their Intensive education courses and even running two Approved courses of my own, which have become popular in their own right. One of these courses takes place in Egypt, the other in the UK, where there is a shortage in opportunities for basic training in the field. Through these initiatives I have introduced more than 70 new members to the Society in the last year alone and strive to continue delivering ISUOG’s resources in areas where there is most in need."

Professor Liona Poon is an Academic Subspecialist in Maternal Fetal Medicine, devoted in improving maternal and fetal health. She has had a prolific research output throughout her clinical and research posts, including over 130 peer-reviewed publications in high impact international journals. In the last 10 years she has focused her research on establishing a programme for effective early prediction and prevention of preeclampsia, a major cause of maternal and perinatal morbidity and mortality. With her success in developing a first-trimester prediction model for preeclampsia using maternal risk factors, ultrasound, blood pressure and biochemical markers, and on Aspirin prophylaxis against preeclampsia, her goal in the next 10 years is to improve obstetric care worldwide, through clinical research and education.
