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.

Heather attained her Bachelor of Technology degree in food engineering from Massey University. She then spent 10 years in gelatine manufacture in various roles including quality assurance, production management and process improvement engineering. In 2015 she completed her PhD study into the rheology of biopolymer soft particle suspensions, supervised by Professor Jason Stokes at the University of Queensland. She has since continued at UQ in postdoctoral roles investigating the relationship between rheological properties, food structure and sensory perception of real food products and model soft particle suspensions with a focus on dairy protein systems. The key outcomes from the project have allowed our industry partner to move towards the rational design of food products.

Professor Jason Stokes is a Professor in the School of Chemical Engineering at The University of Queensland and Program Lead for Premium Food and Beverages within Australia’s Food and Beverage Accelerator (FaBA), providing leadership across a nationally coordinated, industry‑focused research program. His work sits at the interface of chemical engineering, soft matter science and food systems, combining fundamental research with strong industry engagement.

Jason is internationally recognised for his expertise in rheology, tribology and interfacial phenomena, with particular emphasis on how structure, flow and deformation govern the behaviour of complex fluids and soft materials. He is known for pioneering experimental approaches in soft‑contact tribology and aqueous lubrication, providing new physical insight into oral processing, mouthfeel, texture and material performance across multiple length scales.

With more than 25 years’ experience working in and with industry, Jason has led long‑term research partnerships spanning food and beverage manufacturing, materials processing and sustainability‑driven innovation. Prior to joining UQ in 2008, he worked as a Research Scientist at Unilever R&D in the United Kingdom. His current research supports the rational design of next‑generation food and beverage products, including plant‑based and value‑added formulations, by integrating processing, structure and performance.

Jason was named among Australia’s Top 250 Researchers by Research Magazine (The Australian, 2026), ranking first nationally in Dispersion Chemistry within Chemical and Materials Sciences. He has an h‑index of 60 (Google Scholar), reflecting sustained international impact across rheology, tribology and food engineering.
