Glycan utilization is a key evolutionary driver of the gut microbiota. To thrive in the competitive gut environment, expanding catabolism capacity by targeting novel dietary complex glycans is a survival strategy adopted by certain gut microbes. I am interested in how these systems evolve in response to new carbohydrate sources from new dietary changes and their impact on human health. To address these questions, I use a combination of structural, biochemical and microbiological techniques as well as proteomics and high-resolution fluorescence microscopy.
