Dr Stuart Smith is Senior Lecturer in the area of Food Science in the School of Exercise and Nutrition Sciences and is a member of the Australian Institute of Food Science and Technology Inc. Stuart teaches at undergraduate level regarding food safety and food biotechnology and postgraduate level and also supervises higher degree students. Stuart is an active researcher into several areas of food science and nutrition related to health and nutrition in the gut and the role of dietary factors on modulation of gut microbiota with funding from the Gardiner Foundation for examining milk bioactives and their influence on gut health. Stuart has also had several television and newspaper interviews on issues related to food safety.
Supervises 1 PhD student and 1 honours student
Dr Smith’s research interests focus on the role of gut microbiota in health and nutrition and the role of dietary modulation by functional food components, such as prebiotics and probiotics, and food biotransformation in healthy individuals and also in chronic gut diseases such as ulcerative colitis. His research studies have included randomised dietary intervention studies in healthy individuals (dietary fibre studies) as well as clinical studies in conjunction with Box Hill Hospital’s Department of Gastroenterology, demonstrating significant beneficial changes in gut microbiota in ulcerative colitis patients supplemented with varying levels of dietary fibre (wheat bran, resistant starch) in the presence and absence of prebiotic bacteria. Recently, he commenced studies on the differences in gut microbiota in sea birds examining influences of differing habitual diets and geographical location.
