Primary research interest

Metabolism and microbiome in pregnancy

About me

I have a MSc in Medical Biology from the University of Amsterdam, The Netherlands. I moved to Sweden to study the role of Insulin and IGF-1 receptors in endothelial cells obtaining a Licentiate Degree in Medical Cell Biology at Linköping University, Sweden in 2005. I pursued my PhD at Lund University, Sweden in Molecular Metabolism of the pancreatic beta cells (2007).

In my first post-doctoral scholarship funded by the Nordic Centre of Excellence in Disease Genetics and the Swedish Society for Medical Research, I investigated the role of epigentics in the pathogenesis of type 2 diabetes. I then moved to Australia in 2011 to pursue research into metabolism in pregnancy. I am the key scientist of the SPRING RCT team which aims to prevent gestational diabetes mellitus in overweight and obese pregnant women with probiotics.

I joined the School of Chemistry and Molecular Biosciences as a Senior Lecturer in Metabolism and to continue my research into metabolism and the microbiome in pregnancy.

Research focus and collaborations

The focus of the Metabolism and Microbiome in Pregnancy lab is on understanding the role of the microbiome in shaping metabolic changes in pregnancy and pregnancy complications such as gestational diabetes mellitus and preeclampsia. The rate of pregnancy complications is increasing in line with the rise in overweight and obesity in women of childbearing age. Recently, it has become clear that the microbiome i.e. the composite of microorganisms present on an organism, is an important regulator of many physiological processes including metabolism and immunity. The lab uses samples obtained from clinical studies to investigate the mechanisms by which the microbiome regulates metabolism in pregnancy.

The lab has a close collaboration with clinician-scientists at the Royal Brisbane and Women's Hospital: Professor Leonie Callaway and the Mater Mothers' Hospital: Professor David McIntyre and Associate Professor Shelley Wilkinson and with Associate Professor Helen Barrett at the University of Sydney. For our lipid studies, we collaborate with Professor Barbara Meyer at the University of Wollongong and Dr Dilys Freeman at the University of Glasgow, UK. We collaborate with Professor William Hague at the University of Adelaide for our studies on the role of bile acid metabolism and the gut microbiome in women with or at high risk for Intrahepatic Cholestasis of Pregnancy.

Our research group is part of the Queensland Perinatal Consortium (QPACT), a collaboration between research groups interested in perinatal research within South-East Queensland.
