Nikolaos Kazakis received his Diploma in Chemical Engineering with distinction in 2003 from the Department of Chemical Engineering, Aristotle University of Thessaloniki. In 2008, he obtained his first PhD in Chemical Engineering (with distinction) from the same Department, with a dissertation entitled “Study of bubble column equipped with porous gas sparger”. After completing his military service, in 2009 he worked for approximately one year as a Postdoctoral Researcher at the Department of Chemistry, Aristotle University of Thessaloniki.

From 2010 until early 2019, he worked as a Scientific Associate at the Laboratory of Archaeometry and Physicochemical Measurements of the Athena Research Center, while in parallel he served for approximately four years as an External Collaborator at the Quality Assurance Unit (MODIP) of Democritus University of Thrace. In 2018, he was awarded his second PhD (with distinction) in Physics from the Department of Physics, Aristotle University of Thessaloniki, with a dissertation entitled “High-dose dosimetry with emphasis on the industrial sterilization and accidental radiation dosimetry.”

In March 2019, he was appointed Principal Researcher (Researcher B’) at the Athena Research Center in Xanthi, with the scientific field “Dosimetry and Radiation Analytical Methods.” In December 2025, he was promoted to Research Director (Researcher A’) in the same scientific field.

His research activity is primarily laboratory-based. His research interests include archaeometry; post-sterilization and forensic dosimetry; environmental, accidental, and space dosimetry; physicochemical and luminescence measurements of materials using advanced diagnostic and analytical techniques with (and without) the use of radiation; microalgae cultivation, with or without the use of artificial intelligence, for exploitation in a wide range of applications and for green and sustainable development; physicochemical and radiological measurements of materials in the agri-food sector; smart agriculture; and the analysis, simulation, and design of physicochemical processes, with emphasis on gas–liquid two-phase flow (bubble columns and microbubble generation).

He has authored/co-authored more than 80 publications in peer-reviewed international scientific journals and conference proceedings. His published work also includes three theses, three book chapters, and several articles in electronic journals and general-interest magazines. His work has received more than 1,300 citations (h-index: 14).

Since 2004, he has been actively involved in the writing, submission, implementation, and supervision of research projects, funded by both national and European resources. He has participated in numerous national, European, and cross-border projects, serving either as Scientific Coordinator / Deputy Scientific Coordinator or as a member of the project team, as well as in privately funded research and service provision projects.

In parallel, he serves as a reviewer for international scientific journals in the fields of physics, dosimetry, archaeometry, environmental protection, chemical engineering, and medical statistics, and he is a member of the Registry of Certified Evaluators of the General Secretariat for Research and Innovation (GSRI) and the Greek State Scholarships Foundation (IKY). He has supervised student internships, undergraduate and postgraduate theses, as well as postdoctoral researchers within the framework of research projects, and has also contributed teaching activities.

He is a member of EURADOS, IEEE, the Hellenic Artificial Intelligence Society, the Hellenic Archaeometry Society, the Panhellenic Association of Chemical Engineers, the Technical Chamber of Greece, the Union of Greek Researchers, and the Researchers’ Association of the Athena Research Center.
