Deirdre is a Microbiologist with experience in molecular microbial ecology techniques, bioinformatics and fermentation microbiology.
Deirdre has a B.Sc with First Class Honours in Microbiology (1999) and PhD in Microbiology (2005) from The University of Queensland (UQ, Australia). She worked at the Advanced Wastewater Management Centre (UQ; 2005), until moving to the Centre for Nutrition and Food Sciences (CNAFS) in 2006. She worked as Postdoctoral Research Fellowship and Research Fellow in CNAFS, Queensland Alliance for Agriculture and Food Innovation, UQ. Deirdre joined the School of Agriculture and Food Susstainability in 2019 as a Teaching and Research Academic, and is presently a Senior Lecturer in Food Science. She course coordinates and lectures FOOD2000 Food Science, FOOD3017 Food Safety & Quality Management and the work integrated learning course FOOD7021 Professional Experience. Deirdre's research is molecular microbial ecology and biopolymer science-based, aiming to provide a mechanistic understanding of how foods, diets and nutrients influence the host gut microbiota. Deirdre has 75 peer-review publications with an h-index of 26 and 2746 citations.
Deirdre is a Member of the Australian Institute of Food Science and Technology (AIFST) and sits on the Queensland Branch Committee. She is also a Member of the Australian Society for Microbiology (ASM). Deirdre is part of the International Union of Food Science and Technology (IUFOST) Food Safety Working Committee, in an education-focused role.

Research impacts
Deirdre is a passionate microbiologist, with a strong research background in molecular microbial ecology and biopolymer science (construction and fermentation of “model” dietary fibres). Her research predominantly focuses on how food components are broken down by the host’s gut microbiota, be it in human and/or monogastric animal models, and understanding their role in promoting/maintaining host health.
Specifically, hes has worked on:
i) modelling plant cell walls of cereals and grasses;
ii) investigating the fermentability of cell wall components as potential prebiotics;
iii) developing molecular microbiology techniques to investigate gut microbe-dietary fibre interactions; and
iv) investigating how do plant cell walls/dietary fibres alter the gut microbiota in terms of diversity and relative verses absolute abundances.
Over 80% of Deirdre's publicatons are in the top 25% of journals (Q1 journals) in that subject category.To date, she has 75 peer-review publications, and an h-index of 26, with 2746 citations. Her most exciting achievement was a Nature Communications publication in 2020 with CNAFS and KTH Sweden colleagues.
