Our research aims to translate the scientific advancements into practical outcomes by developing dietary strategies that promote health while supporting a more sustainable global food system. Our work focuses on understanding the role of food ingredients in promoting digestive system health, with a particular emphasis on gut microbiome modulation, metabolite production, and the integrity of the gut barrier including tight junction. We employ both in vitro and in vivo models to explore an understanding of gut health and its implications for overall well-being. Additionally, we are actively engaged in the development of biorefinery processes using both conventional techniques and innovative methods to extract high-value bioactive compounds for processing algal biomass and agricultural products. These bioactive compounds are evaluated for their potential applications in functional foods and nutraceuticals, with a particular interest in properties such as prebiotic activity, antimicrobial effects, and the modulation of carbohydrate and lipid digestion to achieve lower glycemic responses.
