George-John NYCHAS [3 pages cv)
Professor George-John Nychas is the head of the Laboratory of Microbiology and Biotechnology of Foods (LMBF) of AUA, which was established in 1994. From March 2010 till July 2011 was the President of the Greek National Food Authority (EFET - Eniaios Foreas Asfaleias Trofimon  He was member of the EFSA – Biohazard group, expert in Predictive modelling / Quantitative Risk Assessment (QRA) while recently he has joined the ERWG of EFSA. He has coordinated 6 EU projects and participated in more than 35 EU projects & concerted Action. Through these projects, the team of Prof. G. Nychas has acquired extensive experience on; a) the assessment of food safety and spoilage through microbiological analysis (pathogens spoilage organisms), and physicochemical analysis (metabolomics) in combination with multivariate statistical methods, such as MCFA, PCA, discriminant analysis and cluster analysis, b) on responses of stress adapted pathogens grown planktonically or attached on stainless steel surfaces (biofilms), and c) on modelling the behaviour of microbial populations throughout the food chain to assist reliable estimation of microbial food safety risk. d) Implementation of Process analytical technology (PAT) in Food Industry. He has published 278 papers (Scopus 20-10-20) with ca. 14120 citations and h=69.
