Researcher Profiles

Dr Joel Gummer, Research Fellow

Joel is an early-career researcher focused on the application of high-resolution instrumentation to the study of metabolites and peptides in complex biological systems. His wide-ranging research interests include the application of metabolomics to study amphibious host response to chytridiomycosis, a fungal infection of frogs, as well as investigating free fatty acids as predictive biomarkers for Alzheimer’s disease.

One of the projects Joel is leading involves the development of a novel assay for the quantitation of the human peptide hormone hepcidin. Hepcidin, a liver-expressed peptide and central regulator of iron homeostasis in animals, is being increasingly recognised as a key diagnostic marker, with its measurement likely more relevant than traditional measures of iron metabolism to numerous disease diagnoses. Using the Waters Synapt G2-S Imaging mass spectrometer, Joel was able to develop a highly-reproducible and accurate method to quantitate endogenous hepcidin in human plasma. He is now working with research collaborators to provide a testing service at the national level.

Expertise: High resolution MS, untargeted metabolomics, hepcidin biomarker, mass spectrometry imaging.

Dr Hayley Abbiss, Post-Doctoral Research Fellow

Hayley is a post-doctoral research fellow within the Premier's Agriculture and Food Fellowship Program at Murdoch University and Curtin University's Centre for Digital Agriculture. Hayley graduated with first class Honours from Edith Cowan University majoring in applied and analytical chemistry and environmental management. She recently completed a metabolomics based PhD at Murdoch University in the Separation Science and Metabolomics laboratory. Her research is centred on applying metabolomics to detection anf management of stress in agricultural systems and quality assessment of produce. Hayley brings to the group expertise in analytical chemistry and development knowledge in the software for mass spectrometry-based metabolomics applications.

Expertise: Data analysis, analytical chemistry, untargeted metabolomics, agriculture, grain quality.
