I have a strong background in fetal growth, reproductive endocrinology and placental physiology. My research has examined aspects of placental and myometrial function. My research interests have evolved into an investigation of those factors that program fetal development and neonatal adaptation, particularly in the areas of cardiovascular adaptation and neonatal immune development.
Asthma is the most common complication experienced by women during pregnancy. In our ongoing work, we are studying pregnancies complicated by asthma to understand how inflammation affects pregnancy outcomes. Our results have been startling, identifying an important sex dependent difference in the fetal growth response to maternal asthma. The results have been recognised both internationally and nationally, with publications in the asthma and obstetric literature and reviews in leading journals. Clinically our studies have demonstrated that asthmatic women require extra care during their pregnancies. Scientifically this work has started to create a picture of what sex specific factors are involved in preterm delivery and fetal development in pathological pregnancies. More recently we have found that the sex specific differences in fetal growth in pregnancies complicated by asthma are also present in pregnancies complicated by pre-eclampsia and in pregnancies that deliver preterm. Our ongoing work will further research these mechanisms.
My research interests have been extended through collaborations with leading researchers both internationally (Canada; Poland) and nationally (Hunter Medical Research Institute and the University of Newcastle). This research includes assessment of dietary factors that impact upon maternal asthma in pregnancy, identification of novel proteins that are expressed in the placenta that may contribute to altered placental function in women with asthma and pre-eclampsia, as well as animal modelling of gestational infection.
