We aim to understand the role of botanicals and gut microbiota in the development and potential management of metabolic dysfunction in obesity, diabetes, physical fitness, and inflamed states.
Metabolic dysfunction is on the rise as a result of major changes in socioeconomic lifestyles, cultural practices, and the challenges posed by the modern agricultural systems. These shifts are reshaping global diets, creating a pressing need to understand and develop new functional ingredients that provide both affordable and nutritious options in support of optimal health outcomes.
By investigating how plant-derived ingredients and microbial communities that digest them influence metabolic pathways, we seek to uncover novel strategies for targeted dietary interventions that enhance overall metabolic resilience.
By leveraging advanced pharmacogenomics and microbiome profiling, we aim to identify individualized approaches to management, offering more precise and effective interventions.
Within this overarching theme, our research focuses on three major initiatives:
|
- 1) Investigating the interactions between foods, botanicals, and the gut microbiome to identify bioactive metabolites that influence metabolic and immune pathways, and promote metabolic fitness;
- 2) Conducting preclinical and early phase human studies in support of novel interventions or supplementation strategies, including analytical quantification of the target bioactive metabolites; and
- 3) Mobile Discovery program to engage students and ethnic communities in biodiscovery from nature, and popularize global health research.
