Metabolomics Group

Research Overview

Dysregulation of lipid metabolism underpins multiple diseases including obesity, type 2 diabetes, cardiovascular disease and age related dementia. While lipid metabolic pathways are well characterised, their dysregulation resulting from environmental and genetic influences are less well understood, particularly in a setting of chronic disease. The Metabolomics laboratory has utilised state-of-the-art tandem mass spectrometry to developed the only high-throughput lipidomic platform in Australia and has performed some of the largest clinical and population lipidomic studies yet reported. These have enabled the characterisation of metabolic pathways and identified lipidomic biomarker profiles that are able to better predict disease risk and therapeutic efficacy. Modulation of the same pathways now holds potential as an interventional strategy to prevent, attenuate or treat the major chronic diseases.

The overarching goal of the Metabolomics laboratory is to develop strategies to elucidate and combat the metabolic underpinnings of cardiometabolic disease.

We are applying our state of the art lipidomic capabilities to characterise the relationship between lipid metabolism and cardiometabolic disease. Clinical translation of the outcomes from these studies will deliver new diagnostic/risk assessment/monitoring tests and therapeutic interventions for chronic disease.
