Bio

Research

  • Study the role of gut microbiota in contributing to and preventing obesity and metabolism-associated health issues including fatty liver, systemic inflammation, skin disease, mental and neurological issues, and cancer aiming to uncover means for treatment.
  • Study the beneficial effects of vitamins and natural products such as chemicals derived from tea, β-carotene, milk, or fermentation-generated metabolites.
  • Study the effect of gut microbiota in regulating bile acid synthesis that in turn affects metabolism, insulin sensitivity, immunity, inflammation, and cancer formation or prevention.
