Dr Georgina Williams is a postdoctoral researcher in diet and gastroenterology, working in the Centre for Research Excellence in Digestive Health. Her current research examines the role of the diet in gastrointestinal disease and disorders, with a focus on diet-microbiota interactions.

Georgina completed a Bachelor of Nutrition and Dietetics at the University of Wollongong in 2017 and was awarded her PhD in 2022 from the University of Wollongong.

Her work explored the relationship between diet-microbiota interactions and metabolic health outcomes, including non-alcoholic fatty liver disease. This research strengthened evidence pertaining to the role of dietary fibre, particularly from whole grains, in modulating the gut microbiome with potential for health benefits.

A key finding of this research was the realisation of limitations in current diet-microbiota study design which has hindered research outcome translation, resulting in uncertainty in both consumer and dietitians. This research sparked Georgina’s interest in bettering research methods in diet-microbiota studies to ensure outcomes are useful for translation to nutrition practice. At present, this work is focussed on how diet-microbiota interactions can be in utilised to improve dietary management of gastrointestinal disease and disorders. This includes enhancing dietary assessment of microbiota accessible nutrients.

Georgina also works as a dietitian in private practice and is passionate about providing personalised, evidence based dietary management of gastrointestinal conditions and digestive health.
