Nikolaos Mellios

Nikolaos Mellios serves as Laboratory Teaching Staff in the Department of Civil Engineering at the University of Thessaly's School of Engineering, where he instructs undergraduate courses including Wastewater Treatment, Environmental Engineering, and Chemistry for Engineers, alongside postgraduate coursework on Water-Energy-Food Nexus governance. His academic foundation spans environmental engineering and computational modeling with direct applications to sustainable resource management.

His educational credentials include:

• Diploma in Environmental Engineering from Technical University of Crete (thesis on wastewater odor control)
• Master's in Applied Engineering and Systems Simulation from University of Thessaly (Lake Karla modeling)
• Doctoral Degree in Civil Engineering from University of Thessaly (2020, thesis on freshwater ecosystem informatics)
• Postdoctoral Research at University of Thessaly (2023-present, climate change impact modeling)

Mellios' research integrates environmental informatics and nexus thinking to address critical water challenges through computational modeling. His work demonstrates particular expertise in hydrological simulation, ecosystem dynamics, and machine learning applications for predicting cyanobacteria risks and water demand. He actively develops decision-support frameworks for sustainable agricultural water use and climate-resilient basin management.

Analysis of his 15 most recent publications reveals a concentrated focus on integrated Water-Energy-Food-Ecosystems (WEFE) modeling, with increasing emphasis on Bayesian statistics, incremental learning architectures, and climate change adaptation from 2020-2025. His scholarship consistently bridges theoretical modeling with practical watershed management applications across Mediterranean and Northern European contexts.

Mellios contributes to major research initiatives including Water4Cities (ICT platform for urban water management) and IMPACT (nexus project development), demonstrating commitment to translating scientific insights into operational sustainability tools for complex environmental systems.
