My research
The gut microbiota produces a vast array of metabolites that shape host physiology and immune function. Clarissa Campbell’s team investigates how dynamic changes in microbial metabolism influence intestinal biology and mucosal immunity. The group focuses on how feeding-dependent shifts in microbial activity generate bioactive molecules, such as metabolites derived from dietary fibers and bile acids, that promote regulatory T cell differentiation and maintain immune tolerance.
To address key questions about how these metabolites act in different nutritional states, Clarissa’s team combines candidate-based approaches using curated bacterial molecules with unbiased metabolomics profiling in fed and fasted conditions. They further apply in vitro screening in immune cells and intestinal organoids to identify host targets of microbial signals.
This research provides critical insight into how diet–microbiome interactions regulate immune homeostasis, with implications for understanding and treating inflammatory and metabolic diseases.
