Dr Vassilis Kontogiorgos

Senior Lecturer in Food Chemistry

School of Agriculture and Food Sciences
Faculty of Science


Dr. Kontogiorgos has received his B.Sc. and M.Sc. degrees in Food Science from the Aristotle University of Thessaloniki (Greece). A full scholarship was then awarded from the Greek State Scholarships Foundation (I.K.Y) for Ph.D. studies in Food Science at the University of Guelph (Canada). After his Ph.D. degree, he worked as an NSERC research fellow at the Agriculture and Agri-Food Canada (Canada). Following that post, he worked as academic at the Department of Biological Sciences of the University of Huddersfield (UK) before joining the School of Agriculture and Food Sciences at the University of Queensland. Dr. Kontogiorgos research interests are focused in the area of polysaccharide characterisation and physical chemistry of food macromolecules, gels, and colloidal systems. Currently, he is working on the physical, chemical and technological properties of soluble and insoluble fibres extracted from agricultural wastes. Dr Kontogiorgos is Associate Editor of Food Hydrocolloids and Associate Editor of Food Biophysics.

Research Interests

  • Isolation and characterisation of polysaccharides
    Isolation and characterisation of polysaccharides from agricultural wastes with a view to incorporate them into foods as functional ingredients or use them as advanced biomaterials.
  • Interfacial arrangement of polysaccharides
    Arrangement of polysaccharides at the oil-water interface to create bioactive delivery systems.
  • Nutritional improvement of cereal-based foods
    Design of cereal-based foods as a vehicle for dietary fibre delivery
