Research Interests

Research Interest

Shyam is interested in nutrition, metabolomics and gut microbiota-related research. His research expertise draws on developing analytical protocols for targeted and untargeted metabolomics research. Shyam focuses on evaluating the potential beneficial effects of dietary fiber in modulating gut microbiota and its metabolites using animal and human clinical trial models. His long-term research interest lies in mechanistic-based multidisciplinary studies to explore novel roles of micronutrients, plant-based bioactive components and secondary metabolites in treating metabolic and chronic diseases.
