Obstetrics & Gynaecology

Research Staff

Associate Professor George Condous



George Condous is consultant gynaecologist at Nepean Hospital in West Sydney. He is Associate Professor in Obstetrics and Gynaecology and Nepean Head of Discipline 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.

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 Interests
  • 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 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.

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, then joined Nepean in 2002 and is Professor in Obstetrics & Gynaecology at the Sydney Medical School Nepean, University of Sydney.
Professor Dietz is Editor of ‘Ultrasound in Obstetrics and Gynecology’ and Associate Editor of the ‘Australian and New Zealand Journal of Obstetrics and Gynaecology’.
He is active in a number of national and international scientific societies such as CFA, RANZCOG, IUGA, ISUOG and ICS and has published 228 peer-reviewed papers (H factor 50 in 2014), and 14 book chapters, the vast majority relating to ultrasound imaging in Urogynaecology.

He has been active in urogynaecological imaging research since 1986. Since coming to Nepean, he has organised over 50 imaging workshops at urogynaecological and imaging meetings.
His current research interests include , pregnancy and childbirth- related pelvic floor trauma and the ethics of professional conduct, in particular as regards the industry- research interface.

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.
