I have supervised a MS thesis student for acadelic year 2023-24 as 'tutor' and she successfully defended her thesis in June 2024. She worked on anaerobic co-digestion of food waste and sewage sludge and compare the system performance and stability of single- and two-stage anaerobic digestion system. Besides, she also explored the effect of carriers in digestion process as it could help the system (in terms of performance and stability) or not?
