Ass. Prof. Vicky Papadopoulou-Lesta (VPL) (EUC) is the Project Coordinator, leading the WP1 and WP 3 and actively participating in all WPs of the project.  VPL is currently an Assistant Professor in the Department of Computer Science and Engineering at European University Cyprus. Her research interests span the Theory of Algorithms and Complexity, with focus on Graph Theory, Computational Complexity, Algorithms (Approximation, Combinatorial, and Parallel) and Game Theory.

 

Her research work has been published in several journals of worldwide recognition in the field of Theoretical Computer Science, such as Algorithmica, Theoretical Computer Science and Computer Networks journals and top conference proceedings and has been supported by several Research and Development projects funded by the European Union and Cyprus.

 

She served as Chair of the Organizing Committee and co-editor of the Spring LNCS proceedings of the 2nd International Symposium on Algorithmic Game Theory and also as Program Committee member in one of the most prestigious international conferences in Computer Science, the 42nd International Colloquium on Automata, Languages, and Programming (ICALP 2015).  VPL is a founding member of the AHPC (Astrophysics and High Performance Computing) research group of European University Cyprus.

 

Almost all of her research results and activities utilize Graph Theory in order to model real problems of a wide range of applications in many domains, such as resource allocation, network security and network monitoring and control. The graph theoretical modeling is usually utilized in a multi-level approach together with graph theoretic tools, combinatorial, computation complexity and algorithm design tools for investigating the structural properties of the problems addressed, characterize the hardness the problem solving and finally providing algorithmic solutions for it, of guaranteed performance (through approximation algorithms).

 

Her research interests span the Theory of Algorithms and Complexity, with focus on Computational Complexity, Graph Theory, Algorithms, Approximation and Combinatorial Algorithms, Parallel Algorithms, Algorithmic Game Theory, Distributed Systems. Applications of her works include Facility Allocation problems, Topological etwork Control, Frequency Assignment, Wireless (Sensor) Networks: Communication, control and others, and Mobile Computing.

 

Her scientific results have been published in several journals of worldwide recognition, such as Algorithmica, Theoretical Computer Science and Computer Networks journals. She also published her work in numerous well known conference proceedings. Her research has been supported by several Research and Development projects funded by the European Union and the Cypriot state. She served as Chair of the Organizing Committee of the 2nd International Symposium on Algorithmic Game Theory that took place in Paphos in October 2009 and she was co-editor of the corresponding Spring LNCS volume. She also served as Scientific Program Committee in one of the most prestigious worldwide international conference in Computer Science, the 42nd International Colloquium on Automata, Languages, and Programming (ICALP 2015). She is a regular reviewer in prestigious journals of Theoretical Computer Science, such as the Theoretical Computer Science journal.
