Nikolaos Nikolaidis is a professor in the Department of Environmental Engineering and Director of the HersLab. Prior to joining TUC, he was a professor and director of the Environmental Engineering Program at the University of Connecticut, USA. His areas of expertise include: Watershed Scale Studies and Modeling, Heavy Metal Site Assessment and Remediation, and Pollution Prevention and Sustainable Development. He is using a “holistic” approach in solving environmental problems by conducting field studies, laboratory experimentation and mathematical modeling. Dr. Nikolaidis has participated in several EU and National funded projects (SoilTrec, Charms, CONDENSE, EUROCAT, tempQsim, EnviFriendly, AquaTrain, MIRAGE, SoilCritZone, CyberMan). Dr. Nikolaidis has extensive experience on watershed monitoring and modeling in Greece, Europe and the US. He has studied major watersheds in Greece such as Axios, Evrotas, Krathis, Keritis, Koiliaris and Acheloos River (10% of Greece) and he has developed watershed models such as the ETD model, the NTT model and the HM-1D and 3D models. Recently, his developed the Reach Scale tempQsim model for temporary rivers and the Karstic model for predicting the flow and water quality of karstic hydrogeologic systems. He is currently working towards the development of an integrated soil critical zone model as part of the SoilTrec project.
