Overview
Background
Since joining the Centre for Nutrition and Food Science in 2004, my work has focussed on food structure and how it changes during digestion and fermentation. I use NMR spectroscopy and wet chemistry techniques, to characterise polysaccharides particularly: starch, plant cell walls, dietary fibre and cellulose. My research has resulted in the publication of 93 papers with over 6000 citations and a H-index of 39 (scopus). I regularly review papers for Food Hydrocolloids and Carbohydrate polymers. I have co-supervised eight PhDs to completion and am currently co-supervising four PhD students and am principal supervisor to one PhD and two masters students.
After graduating with a Bachelor of Science (Honours, 1997, UQ) and PhD in Inorganic Chemistry (2002, UQ) I worked with Prof David Fairlie (h-index 104, 42, 140 citations) to study peptide synthesis and high-field, multi-dimensional NMR.
I have practical experience with in vitro and digestion and fermentation and havecollaborated to perfect a batch fermentation system to compare the fermentability of a number of complex dietary fibres using human faecal inoculum. Using this methodology, I have studied how the chemistry and architecture of dietary fibres affects the digestion and fermentation of starches and dietary fibres. My Skills in NMR spectroscopy have enabled me to develop methods for quantifying starch molecular order and to quantify Short Chain Fatty acids and other fermemetabolites.

Investigating food structure and how it affects digestibility and fermentability.
Characterising starch and dietary fibres and exploring how they change in response to differences in processing conditions. How does food architecture affect the digestibility and fermentability of food and feeds. Using spectroscopy and analytical chemistry techniques to explore the composition and structures of food and feeds. Determining how the interaction of plant cell wall polysaccharides influences their structure and function with particular focus on the interactions of cellulose hemicelluloses. How the density and solubility of plant cell wall components drives fermentability.
Research impacts
Over the last twenty years (13 years FTE) I have been part of many multi-disciplinary teams working with industry, government and fellow university based researchers nationally and internationally. For Six years as part of the CSIRO Food Futures Flagship and then for 7 years as a member of the ARC Centre of Excellence for Plant Cell walls, a team of over 80 researchers, based at UA, UM, ANSTO and international collaborators in the UK and Sweden. These collaborations lead to many multi-disciplinary publications with a focus of polysaccharide structure and function. Using NMR, I established new methods for polysaccharide structure analysis and increased our understanding of complex plant cell wall structure relationships.
In 2005 I was awarded a UQ New Staff Research Start Up Fund. In 2023 I was a CI on a successful $1.68 million ARC LIEF bid for a national network for magnetic resonance spectroscopy. I am a CI on a recently awarded a $788, 130 ARC Linkage grant, LP240100343, in this project I will lead the activities in polysaccharide structure and characterisation. As a result of my interest in plant polysaccharides, I was voted Vice Chair of Australasian Grain Science Association (AGSA) and was appointed 2025 AGSA Brisbane conference chair.
