Alexandra is currently in the final year of her PhD studies at The University of Western Australia. She obtained a Bachelor of Medical Laboratory Science from the University of Otago, and worked as a clinical scientist in New Zealand, before quickly realising her passion for research using advanced technologies such as mass spectrometry. She moved to Perth, initially studying vitamin D metabolites using mass spectrometry. Her passion for MS continued on to a PhD, in which she is currently using it to investigate the human milk lipidome and understand how lipids contribute to infant growth, development and health. Due to the enormous impact that early nutrition has on human outcomes, the aim of research like this is to encourage evidence-based guidelines for infant and maternal nutrition, to ultimately improve both short and long term health.
