- Extract polysaccharides and recover chitosan from shellfish waste
- Quantify and characterise extracts by HPLC-DAD, LC-MS, GC-MS, GC-FID, NMR, FTIR, UV-Vis, SEM, XRD and TGA
- Determine yield, purity and physicochemical properties (pH, solubility, thermal stability)
- Develop functional (nano)capsules of bioactives in lignin, chitosan and pectin by ionic gelation, nanoprecipitation and spray-drying, or by biopolymer grafting
- Characterise nanocapsules (DLS, zeta potential, SEM, FTIR, DSC, TGA) and their stability
- Study biopolymer-phenolic interactions
- Help supervise undergraduate students
- Write project reports and scientific articles
