- Perinatal Sleep Research: Institute for Breathing and Sleep, Austin Health
Dr Mark Howard, Sleep Physician Clinical Researcher
Ms Danielle Wilson, sleep scientist, PhD scholar
Sleep disordered breathing and obstructive sleep apnoea are more common in pregnancy, and are increased further among women who are obese. Given that over half the antenatal population are overweight or obese, research in this area may help unravel the links between obesity and hypertension in pregnancy,problems with fetal growth, and stillbirth.

Dr Cathy Cluver, Research clinician
Dr Cluver undertook fellowship at Mercy Hospital for Women in 2013, and has returned to CapeTown to run the Pre-eclamspia Intervention with Esomeprazole trial.
Close links continue with teaching and research between our institutions.

Professor Jane Halliday
Dr Lisa Hui is one of the international leaders in the area of non invasive prenatal testing, prenatal testing trends and cell free nucleic acids as biomarkers of health and disease. This research has arisen from a strong collaborative partnership with Professor Jane Halliday at MCRI
- Contribution to National and International Trials
The Mercy Hospital Perinatal Research Group provides obstetric leadership for the following national and international externally funded major obstetric trials: the Australian Placental Transfusion Study, the EPPI Trial – Enoxaparin for the Prevention of Preeclampsia and Intrauterine growth restriction, and the MAGENTA trial: Magnesium Sulphate at 30-34 weeks’ gestational age: neuroprotection trial, and the STRIDER Trial: a randomised controlled trial of Sildenafil in Dismal Prognosis Early-onset Intrauterine Growth Restriction.
- LaTrobe University
Collaborations in the areas of fetal growth restriction, improved fetal surevillance in high risk pregnancy
- Deakin University
Collaborations in the areas of diabetes, obesity and metabolic disorders in pregnancy
- Austin Health
Collaborations through research in high risk pregnancy, including infectious diseases, cardiology, transplant medicine, diabetes and hypertension
