Microbes in Food and Human Health
Microbial ecology addresses which microbes inhabit an environment, how their community structure and composition change, what their functions are, and how they work together to maintain a sustained and balanced ecosystem functioning. Our group studies the microbiota associated with the human and food fermentation microbial ecosystems using omics, and microbial culturomics approaches with the objective to define the following four key areas of molecular microbial ecology:
- Community assembly, formation, succession, distribution, and core microbiome.
- Linking community structure and composition to function.
- Molecular mechanisms underlying ecologically and evolutionarily relevant processes occurring between and within microbial communities: Elucidating intra- and inter-community and host-microbiota interactions.
- Utilizing the microbial resources, and the microbiome data to develop functional microbial consortium, and microbial-derived interventions and predictive models for improving human health.
The current areas of research interest are:
- Gut and reproductive tract microbiome as a therapeutic target for improving women health.
- Understanding the microbial community structure, composition, dynamics, interactions, and functions in traditional fermented foods as the model tractable microbial ecosystems.
- Fermented foods and human health: Impact of traditional fermented foods, and its microbiota and microbial-derived metabolites on the host gut microbiota and metabolome.
