Nikos did his undergraduate studies at the Crop Science Department of the Agricultural University of Athens (Greece) in 2005. Upon completion of his studies, he moved to Spain to obtain his PhD degree from the Faculty of Enology (University Rovira i Virgili) under the supervision of Dr. Fernando Zamora and Dr. Joan Miquel Canals. His PhD was focused mainly at the influence of grape phenolic maturity on wine phenolic composition. He obtained the PhD at 2010 and continued forming part of the same research group working on different subjects related with wine technology. He joined NWGIC in October 2014.
Specialisation: Wine technology
Focus area: Wine metal ion speciation
It is important understanding the role of metal ions on wine development. Iron and/or copper involved in oxidation and reduction reactions, casse development and the formation of sulfur containing compounds. Both iron and copper exist in a variety of forms including different redox states, and either free or bound by wine components with varying binding strengths. The agents responsible for the most efficient binding of metal ions in wine are not known nor are their reactivity and roles in wine spoilage. The use of current research tools that measure different forms of metal ions (metal speciation) will permit a comprehensive understanding of the relation between speciation measures and metal-induced processes in wine. The components of wine able to interact with metal ions to form inert or 'non-active' metal species will be identified. Develop speciation measures that provide a good predictor of metal activity (i.e. responsible for specific detrimental wine effects) is necessary as a more routine analytical method suitable for the wine industry.
