Our focus is to study and develop microbes that are useful for food and gut health. We combine screening and fundamental characterization with functional and mechanistic studies to study microbes from the environment, food and gut ecosystems. In addition, innovative bioprocessing technologies are also developed. The role and functions of the human gut microbiota, bacteria and artificial consortia on host health and their response to food and nutritional components are investigated using integrated multi-scale in vitro and in vivo strategies.
