Graduated from the Department of Agricultural Biotechnology of the Agricultural University of Athens (2002), holder of a Master’s Degree (MSc) in "Food Science and Technology" (2003) from the Department of Food Science and Technology and of a PhD Degree in Agricultural Sciences, scientific field of Food Microbiology, from the same University (2008). An important part of his doctoral thesis (2004-08) was executed at the Units of: (i) Bacterial Biochemistry, and (ii) Bioadhesion and Hygiene of Materials, of the French National Institute of Agricultural Research (INRA-AgroParisTech, Research Centre of Jouy-en-Josas, Paris), where he worked for 20 months, as a recipient of a European Union Marie Curie fellowship (for Early Stage Research Training). He conducted postdoctoral research at the Laboratory of Microbiology and Biotechnology of Foods at the Agricultural University of Athens, through a 12-month scholarship provided by the Greek State Scholarship Foundation (IKY), whose main research interest was to study microbial interactions encountered in biofilms formed by food-related bacteria and their influence on the disinfection resistance of these communities. He was appointed Lecturer of Food Microbiology at the Department of Food Science and Nutrition, of the University of the Aegean in 2010 and in 2014 was promoted to the rank of Assistant Professor. So far, he has participated as a paid research assistant in 8 European research projects on topics of food microbiology and safety. He is the author/co-author of 31 articles in international scientific peer-reviewed journals (which have received over 800 citations, h index 14, https://www.scopus.com/authid/detail.uri?authorId=14032869700), 6 chapters in collective English volumes, while he has also announced his research project more than 70 times in national (Greek) and international conferences (through 22 lectures and 50 posters). He has supervised over 25 Graduate Studies on food microbiology and safety issues. He is member of the editorial board of 9 international scientific peer-reviewed Journals, including Heliyon (Elsevier)”, “International Dairy Journal (Elsevier)”, “Journal of Food Quality (Wiley and Hindawi)”, and “Journal of Food Protection (IAFP)”, Topic editor in “Frontiers in Microbiology (Frontiers)”, guest associate editor in “Frontiers in Microbial Physiology and Metabolism”, invited reviewer in more than 70 international scientific peer-reviewed Journals related to applied (food) microbiology and/or food science (having evaluated > 270 works), reviewer of research proposals to the European Institutions, member of the American Society for Microbiology (ASM), of the six-member scientific committee of the Hellenic Association of Food Technologists, of the food safety working group of the Greek Technology Platform "Food For Life", and integrated into the Unified Register of Trainers of Hellenic Food Authority (EFET), as a trainer of staff working in the food industry and food control agencies on topics of food hygiene and safety.
