Research focused on the advanced characterization of complex carbohydrates and the discovery of structure–function relationships. Expertise includes polysaccharide extraction, purification, chemical modification, and structural characterization, with particular emphasis on 1D and 2D NMR spectroscopy (¹H, ¹³C, COSY, TOCSY, HSQC-DEPT, HMBC, NOESY, DOSY, and STD), GC–MS compositional and linkage analysis, SEC–MALS–RI for molar mass and conformational analysis, and complementary physicochemical methods. Research interests include bioactive carbohydrate systems, functional ingredients, food and health applications, biomaterials, and translational carbohydrate technologies.
