His research interests focus on the appraisal of the impacts of long term wastewater reuse for irrigation on the environment and public health, with emphasis on heavy metal accumulation in soil and the agricultural produce, as well as the fate of emerging micro pollutant in treated wastewater, such as pharmaceuticals, personal care products, pesticides and other compounds of emerging concern (CECs), in the environment. He completed undergraduate studies in the Faculty of Agriculture of the Aristotle University of Thessaloniki (Department of Plant Protection), while he holds an MSc degree (MSc in Horticulture) from the University of Reading. He holds a PhD degree from the Cyprus University of Technology (CUT) and his dissertation work was titled ‘’ Priming with signalling molecules for the enhancement of strawberry plants’ tolerance to multiple abiotic stress factors’’. An array of potential priming agents has been examined, including nitric oxide, hydrogen peroxide and hydrogen sulfide. Pretreatment was carried out in a hydroponic cultivation system, while plants were subsequently exposed to a multitude of abiotic stress factors including salinity (NaCl), hyperosmotic stress (PEG), heat and heavy metals. Pretreatment with NO and hydrogen peroxide resulted in the mitigation of NaCl stress, while hydrogen sulfide protected plants against subsequent NaCl, PEG and heat stress. A combinatorial physiological, biochemical and molecular approach was employed for the examination of factors such as physiological parameters (e.g. transpiration and chlorophyll fluorescence), cellular damage indicators (e.g. lipid peroxidation, ion leakage), reactive oxygen & nitrogen species content, ascorbate and glutathione redox state, as well as gene expression of several components including the SOS (salt-overly-sensitive) pathway, AsA/GSH biosynthesis, antioxidants, HSPs etc.
