Alexandra Spyropoulou conducted her postdoc research with fellowship from Stavros S. Niarchos Foundation on the speciation and mobility mechanisms of mercury in groundwater and investigated water treatment methods in the Department of Civil Engineering, University of Thessaly (UTH) in collaboration with the National Centre for Scientific Research “Demokritos”. She holds a PhD in physical oceanography, Department of Marine Sciences, University of the Aegean. Her thesis was on the land-sea-air interaction under the climate change impact carrying out in situ samplings, laboratory analysis and advanced 3d-hydrodynamic modeling, Department of Marine Sciences, University of the Aegean. For her PhD research also worked in the National Oceanography Center of Southampton (NOCS), United Kingdom (UK). She finished her M.Sc. in Coastal Management, Department of Marine Sciences, University of the Aegean. Her thesis of specialization was in the dynamics of the seawater exchange between a semi-enclosed bay and the open sea and its effects on eutrophication. She is awarded physicist from the University of Thessaloniki (AUTH) with specialization in atmospheric and environment field. Her scientific interests extend to marine sciences, dynamic of coastal ecosystems, climate change, heavy metals, water quality, water treatment, water-energy-land-food-climate change-ecosystem nexus and dynamic modeling. She has worked as a PhD candidate at the Danish Hydraulic institute (DHI Water Environment Health) in Copenhagen, Denmark and as new researcher/Marie Curie fellow in the informatics company iQuadrat in Barcelona, Spain. She has been working, since 2006 as a research associate, in several national and EU projects, such as DITTY, ISS-EWATUS, SIM4NEXUS, WATER4CITIES, MAGO, SMARTEN, NEXOGENESIS, NexusNet COST Action CA20138 and ARSINOE. Alexandra is currently working as an adjunct Lecturer and associate researcher at the Department of Environmental Sciences and at the Department of Civil Engineering University of Thessaly (UTH), respectively.
