My research interest lies at the intersection of bioinformatics and enzymology, with a focus on better understanding the population dynamics and synergistic interactions of the microbiota by CAZymology - This in turn leads to the discovery of new Carbohydrate Active EnZyme families, functions and structural folds for the utilization of renewable plant biomass.
