Stamatia Christaki holds a Bachelor’s degree from the Department of Nutrition and Dietetics at Harokopio University of Athens and a Master’s degree in Food Science and Nutrition from the School of Agriculture, Aristotle University of Thessaloniki (AUTH). Her Master’s thesis focused on the development of “green” nanoemulsions based on oregano bioactive compounds and their incorporation into whey cheese to extend shelf life. She is currently a PhD candidate in the Department of Food Science and Technology at the School of Agriculture, AUTH. Her doctoral research focuses on the valorization of agri-food industry by-products, the recovery and characterization of bioactive and functional compounds (e.g., phenolic compounds, polysaccharides), and the development of chitosan-based delivery systems. Her scientific and research interests include the extraction of natural bioactive compounds from various materials using “green” extraction techniques (e.g., ultrasound-assisted, supercritical CO₂, and microwave-assisted extraction) and environmentally friendly solvents (e.g., aqueous cyclodextrin solutions); the extracts’ characterization (e.g., UV-Vis protocols, HPLC-DAD); the evaluation of in vitro antimicrobial activity; and the development and characterization of delivery systems and encapsulation matrices (e.g., nanoparticles, edible films/coatings, emulsions/nanoemulsions, inclusion complexes with cyclodextrins) using techniques such as ionic gelation, spray-drying, and freeze-drying. As a Master’s student and PhD candidate, she has participated in several national and European research projects, including ChitoFOODs, and her work has been published in international peer-reviewed scientific journals (citations: ~250, h-index: 10). In 2023, she was awarded a one-month research scholarship by the National Scholarship Programme of the Slovak Republic (SAIA) to conduct experiments at the Institute of Chemistry of the Slovak Academy of Sciences. In 2024, as a PhD candidate, she received an Excellence Scholarship from the Research Committee of Aristotle University of Thessaloniki (AUTH).
