Biography

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 graduate studies abroad. He moved to Canada where he gained his Ph.D. in Food Science from the University of Guelph, Department of Food Science. After his Ph.D. degree, he worked as a post-doctoral researcher at the Agriculture and Agri-Food Canada (AAFC) for one year. He joined the Department of Chemical and Biological Sciences of the University of Huddersfield in 2008.

He has been working in biopolymer research projects continuously since 1999. He started as a member of Prof. Biliaderis research group and subsequently he joined Prof. Goff research team. He also worked in Prof. Kasapis research group performing part of his Ph.D. experimental work. As a post-doctoral researcher he worked in Dr. Wood and Dr. Tosh polysaccharide research team. His efforts at the present time are focused to set up a biopolymer research laboratory in the University of Huddersfield.

Dr. Kontogiorgos is member of the editorial board of Food Hydrocolloids

Research & Scholarship

Dr. Kontogiorgos research interests are focused in the area of chemistry and physical chemistry of food macromolecules. He has worked with both polysaccharides and protein systems from cereal and dairy sources. His work includes isolation/purification of food macromolecules (proteins and polysaccharides) and characterization of their functionality in food systems using several analytical techniques including, but not limited to, thermal analysis, rheometry, electrophoresis, microscopy (fluorescent, SEM, TEM) and modeling.

He has developed expertise on the behavior of biomacromolecules in the low and high moisture regimes as well as at subzero temperatures. He is also particularly interested on phase separation and gelation phenomena of single and mixed biopolymer systems. Rheological characterization of biopolymers can be considered the as the technique that he has extensive experience and developed considerable expertise. He has conducted both fundamental and applied work in an effort to elucidate the physical properties of the biopolymer systems under investigation. Mathematical modeling of the mechanical responses of biopolymer matrices is also a part of his research areas.

Currently, he is working on the phase behavior of β-glucan/sodium caseinate mixtures and the application of exponential analysis to calculate the relaxation spectrum of gluten network and its components.
