Welcome

Hello and welcome to my site! My name is Vaggelis Douros (Βαγγέλης Δούρος) and I was born and raised in Greece. Vaggelis is pronounced like this. 

Work and Research Experience

I work as a consulant and independent lecturer based in Aachen, Germany. I participate in the design and analysis of 5G & beyond spectrum auctions in collaboration with national regulatory bodies. My experience also includes teaching postgraduate courses at the local univerity and supervising students.

 I enjoy doing interdisciplinary research at the interface between telecommunications engineering and economics. I focus on networks where two or more agents (e.g., mobile nodes, base stations, Internet Service Providers, Mobile (Virtual) Network Operators, Content Providers) make decisions (e.g., level of the transmission power, transmission channel/mode, which and how much spectrum I should lease, how much I should invest in the network) in order to achieve a target (e.g., maximise profit or market share or revenue or a quality-of-service metric) and the decision of each agent influences the level of satisfaction of at least one other agent. In such networks, I am interested in identifying whether the agents have motivation to collaborate or to remain selfish and then I try to predict what will be the outcome of their interaction. Will it lead to a stable status/equilibrium? Is it efficient/fair? If not, could we improve it? Is it unique?  If not, how to compare them? How to drive the outcome to a particular stable status?

The following word cloud visualises key approaches that I use in order to answer some of the above questions. The section Research Interests specifies a number of topics that I have worked. 

Besides exploring these exciting topics, I consider teaching and supervising students a challenging but extremely rewarding experience. 

Previously, I was a post-doctoral researcher, affiliated with the Institute for Networked Systems (iNETS), RWTH Aachen University and a post-doctoral researcher at Orange Labs in Paris, affiliated also with the Laboratory of Information, Networking and Communication Sciences (LINCS). 

Studies

I obtained my B.Sc. in Informatics and Telecommunications from the University of Athens in 2006 and my M.Sc. in Computer Science from the Department of Informatics of the Athens University of Economics and Business (AUEB) in 2008. During my master thesis, I joined the Mobile Multimedia Laboratory. I continued working there as a Ph.D. student under the guidance of Prof. George C. Polyzos and Assistant Prof. Stavros Toumpis. On December 2014, I successfully defended my Ph.D. thesis "Incentives-Based Power Control in Wireless Networks of Autonomous Entities with Various Degrees of Cooperation".
