From 2004 to 2015, Mrs Derlere seconded to the Ministry of the Interior. From 2015 to the present, she has worked at EYDAP, as a foreman of construction projects and in particular in the Research and Development Department.

Research Team Dr. Giannis Papaefstathiou
Dr. Giannis Papaefstathiou is a Professor in the Department of Chemistry at the National and Kapodistrian University of Athens. He completed his Ph.D. in 2002 at the University of Patras. His postdoctoral research was conducted at the University of Iowa from 2002 to 2004. His research interests focus on the development of synthetic strategies for the isolation of new functional inorganic and hybrid inorganic-organic materials (Metal-Organic Frameworks, MOFs, polynuclear metal complexes) within the fields of Coordination Chemistry, Supramolecular Chemistry, Crystal Engineering, Molecular Magnetism, and Materials Chemistry. He has extensive research experience in solution chemistry synthesis, solid-state synthesis (solid-state chemistry/mechanochemistry), hydrothermal synthesis, ion-exchange studies for porous materials, liquid-phase adsorption, single-crystal-to-single-crystal transformations, photoluminescence studies, and ion-exchange of metal-organic polymeric complexes, as well as in various characterization techniques such as crystallography (solving and refining crystal structures, topological analysis of polymeric periodic networks), thermal analysis, various spectroscopic techniques, electron microscopy, and more.
Alexios Plessas joined the research team of Professor Giannis Papaefstathiou in May 2014 as an undergraduate second-year student. He obtained his degree from the Department of Chemistry at the National and Kapodistrian University of Athens in December 2017. He then continued his postgraduate studies, earning his Master’s degree in Inorganic Chemistry in February 2019. Subsequently, he pursued his Ph.D. in Chemistry, which he completed in December 2022. He then continued to work in the same research group as a postdoctoral researcher until May 2024. His research activities have varied over the years but focus on the synthesis and characterization of inorganic complexes, metal-organic frameworks (MOFs), and the study of their magnetic properties, their use as sensors for electrochemical glucose determination in epithelial tissue, and their ability to adsorb heavy metal ions from water. Additionally, he has worked as a crystallographer, solving crystallographic structures using X-ray diffraction on powders and single crystals, for the needs of his own projects and Professor Papaefstathiou’s research group, as well as for other faculty members of the Chemistry Department.
He currently lives and works as a postdoctoral researcher at the University of Sherbrooke in Quebec, Canada.



Research Team Dr. Theodore Lazarides
Dr. Theodore Lazarides received his PhD in 2005 from the University of Sheffield, United Kingdom (under the supervision of Professor Michael D. Ward) on the photophysical devices of supramolecular systems based on Ru(II), Os(II) and Re(I). He continued his research at the University of Sheffield on the synthesis and study of molecular dyads in which a metal ion of the d-domain and one of the f-domain coexist to sensitize the luminescence of the latter in the near infrared. After his postdoctoral research on photocatalytic hydrogen production at the universities of Rochester, USA, and Crete, he worked as a Lecturer at the University of Ioannina before moving to the Aristotle University of Thessaloniki in 2014. Since 2022, he is an Associate Professor at the Department of Chemistry of the Aristotle University of Thessaloniki and his research activity includes the synthesis and study of (1) metalorganic frameworks for sorption and detection applications of environmental pollutants such as heavy metals and nitroaromatic compounds 2) lanthanide organometallic complexes with visible and near-infrared emission and (3) luminescent complexes of the d and f domains for biological applications. Dr. Lazaridis’ research work includes 60 articles in international journals with over 3500 citations and an H index of 32 and over 20 presentations at international conferences in the field of Inorganic Chemistry.
Nikolaos Pliatsios studied at the Department of Chemistry of the Aristotle University of Thessaloniki from 2013 to 2018, when he completed his undergraduate studies. He chose to work on Chemical Synthesis Biochemistry and Bioapplications. As part of his thesis, he dealt with the synthesis of homoleptic and heteroleptic Cu(I) complexes with diphosphines and diimines ligands of extended conjugation. In 2018, he attended the postgraduate program in Synthetic Chemistry, Biochemistry and Applications of the Department of Chemistry of the Aristotle University of Thessaloniki, where he carried out the synthesis and study of photophysical properties, as well as complexes of photocatalytic activity of Cu(I) with heterocyclic thioamides and phosphines. In 2024 he obtained a master’s degree in Food Quality Control from the University of Western Macedonia. From 2022 until today, he has been working on his doctoral thesis at the Department of Chemistry of the Aristotle University of Thessaloniki under the supervision of Associate Professor Lazaridis Theodoros. The subject of this thesis is the synthesis of metal-organic frameworks for the detection and/or binding of heavy metal ions from contaminated waters.
Sofia Alexandra Tsoni works on her PhD thesis at the Department of Chemistry of the Aristotle University of Thessaloniki, under the supervision of Associate Professor Mr. Theodoros Lazaridis. Her research focuses on the synthesis and characterization of organic ligands, as well as the luminescent complexes of sectors d and/or f of the periodic table. In 2019, she completed her undergraduate studies in Chemistry at the Aristotle University of Thessaloniki with a grade of 8.21 and continued with postgraduate studies in Advanced Molecular Synthesis at Imperial College London, where she obtained her degree with Distinction. Sofia Alexandra Tsoni has also worked as a Formulation Chemist at the research company SeraNovo in the Netherlands and at Pfizer as a Chemistry Data Quality Engineer. In summary, she has interdisciplinary research experience (6+ years) in a variety of fields including organic and inorganic synthesis, as well as bioinorganic chemistry.
