Scientific Personnel

Brief Bio

Dimitrios S. Vlachos received his PhD degree from the School of Electrical and Computer Engineering at the National Technical University of Athens. After that he worked for 2 years as a post-doc researcher at the Institute of Nuclear Engineering at the Research Center 'Demokritos' and for 8 years as a researcher at the Hellenic Center for Marine Research. From 2007 he is working as an Assistant Professor (αnd from 2012 as Associate Professor) at the Department of Computer Science and Technology, University of Peloponnese. His research interests focus on Discrete Variational Theory, Complex Networks, Evolutionary Algorithms and Physical Modeling. Prof Vlachos is the author of more than 120 papers published in Scientific Journals and Conference Proceedings. He is currently the director of the Laboratory of Mathematical Modeling and Complex Systems at the University of Peloponnese.
