Research Staff

Professor Hans Peter Dietz


Professor Hans Peter Dietz graduated from Heidelberg University, Germany, in 1988, obtaining an MD there in 1989. After emigrating to New Zealand in 1990, he arrived in Australia in 1997 and completed his FRANCOG training in 1998. Between 1999 and 2002, Dr Dietz undertook urogynaecology subspeciality training in Sydney and obtained a PhD with the University of New South Wales. Since 2004 he is Associate Professor in Obstetrics & Gynaecology at the Nepean Clinical School, University of Sydney. He has recently been appointed Editor of the ‘Australian and NZ Continence Journal’ and is member of the Editorial Board of ‘Ultrasound in Obstetrics and Gynaecology’. His main research interests are pelvic floor imaging and the prediction of delivery mode.

Research Interests


  • Pelvic Floor Trauma in childbirth: diagnosis, prediction, prevention, surgical correction.

Professor Michael Peek



Professor Michael Peek is Associate Dean of Nepean Clinical School . He has been Professor of Obstetrics and Gynaecology at Nepean Hospital since 2001. Michael carried out his medical degree at the University of Sydney and his specialist training in Obstetrics and Gynaecology at King George V Hospital. He is a subspecialist in Maternal Fetal Medicine and has previously worked at Queen Charlotte's Hospital, London, and The Canberra Hospital, ACT.

Research Activities

Professor Peek's research interests include the screening for and management of pre-eclampsia, the use of stem cells for ischaemic neurological damage in neonates, preterm delivery, and the audit of medical disorders in pregnancy. His passion for obstetrics and obstetric research was based on the belief that if you can provide someone with a healthy start to life they are more likely to reach their full potential. Thus better health care and more research around the perinatal period will have a profound positive effect on society.


  • Obesity in pregnancy
  • Also many projects in collaboration with paediatrics such as the role of Treg cells in pre-eclampsia
  • Two current NHMRC Project Grants. One looking at national reporting systems for obstetric morbidity and the other rheumatic heart disease in pregnancy.
  • Participation in a number of multicentre RCTs including FACT and CIPS Trials.

Professor Ron Benzie

ron benzie


Professor Ron Benzie’s main research interests for the past years have been in the field of prenatal diagnosis. He founded the international fetal anomaly database PLATYPUS (Programme Listing Abnormality and Prenatal Ultrasound) and is involved in the development of electronic aids to diagnosis and the assessment of their role in medical education. His current research is concerned with prenatal fetal diagnosis using 3D and 4D ultrasound technology.

Associate Professor George Condous



George Condous is consultant gynaecologist at Nepean Hospital in West Sydney. He is Associate Professor in Obstetrics and Gynaecology at Nepean Clinical School, University of Sydney. He runs the Acute Gynaecology Service which sees women with emergency gynaecological as well as early pregnancy complications (miscarriage and ectopic pregnancy). He is also responsible for the One-Stop Ultrasound based diagnostic clinics; which review women with abnormal uterine bleeding, chronic pelvic pain, adnexal pathology as well as post-menopausal bleeding. He is also performs Advanced Endosurgery procedures for women who need intervention for pelvic masses, frozen pelvis, endometriosis or hysterectomy.

Having completed his undergraduate degree with the University of Adelaide, he left Australia in 1993 and moved to London where he completed his training in Obstetrics and Gynaecology. From 2001 – 2003 he worked as a Senior Research Fellow to Tom Bourne at St George’s Hospital, London. At St George’s he set up the Acute Gynaecology Unit, the first in the United Kingdom, which used ultrasound at the point of the initial consultation to evaluate women with gynaecological problems. It was also during this position that he developed his great interest in Early Pregnancy and especially the management of pregnancies of unknown location (PULs). He has developed many mathematical models for the prediction of outcome of PULs which have featured in peer review journals. In 2005, he returned to Australia where he completed his Laparoscopic Fellowship at the world recognised Centre for Advanced Reproductive Endosurgery, Sydney.
He was appointed as a consultant Gynaecologist and Senior Lecturer at Nepean Hospital in 2006 and soon was made Associate Professor. He obtained the MRCOG in 1999 and was made FRANZCOG in 2005.

He has edited one book entitled the Handbook of Early Pregnancy Care, published over 50 papers in international journals and is internationally renowned for his work in early pregnancy. He is the Associate Editor for Gynecologic Obstetric Investigation, which is a European based journal, as well as on the organising committee for this year’s Australian Gynaecological Endoscopy Society (AGES) meeting in Sydney. His current research interests relate to the management of ectopic pregnancy, PULs and miscarriage, as well as the use of sonovaginography to predict rectovaginal endometriosis.

Associate Professor Max Mongelli



Associate Professor Max Mongelli graduated from the University of
Sydney. He underwent specialist and clinical research training in the
United Kingdom, where he developed an interest in perinatal medicine and fetal growth. His other research interests include clinical applications of computer modelling, biostatistics and evidence-based medicine. He is a Fellow of both the RCOG and the RANZCOG and is currently a full-time specialist obstetrician at the Nepean Hospital.

Dr Clara Kai Shek - Clinical Lecturer and Urogynae Research Fellow


Dr Ann Quinton - Research Fellow and Senior Sonographer


Ann Quinton graduated from the University of Sydney in 1998 with a Bachelor of Applied Science (Medical Radiation Science). Ann then obtained postgraduate qualifications from the University of Sydney with a Masters of Health Science (Ultrasonography) awarded in 2001 and a PhD (medicine) in 2011. Ann works at the Nepean Centre for Perinatal Care, Nepean Hospital Penrith where she performs obstetric and gynaecological ultrasound and is involved in ultrasound training and education.
Ann’s research interests are assessing endothelial function in pregnancy and pre-eclampsia using the ultrasound technique of flow-mediated dilatation, ultrasound assessment of the fetal thymus in pre-eclampsia and assessing the role of obesity in pregnancy in the prediction of adverse outcomes. Ann is a council member (scientist) for the Society of Obstetric Medicine of Australia and New Zealand (SOMANZ). Ann is also involved in education and training with the Australian Sonographers Association (ASA).
