My research interests are in the areas of algorithms and complexity. I am especially interested in the
design of efficient (exact or approximation) algorithms for optimization problems arising in computer
and communication systems and networks, combinatorial optimization, graph theory and game theory.
I am a member of our Department's Theory group.

Most of my publications can be found in DBLP Computer Science Bibliography Server;
a complete list is available here.

I am also a co-author of the next book (in Greek):
J. C. Cavouras, I. Milis, G. Xylomenos, A. Roukounaki, Distributed Systems with Java,
Kleidarithmos Editions, Athens 2005, pages xiv+557, ISBN 960-209-829-5.

I am teaching:
Algorithms (AUEB, Dept. of Computer Science, Spring 2014)
Topics in Algorithms (AUEB, Dept. of Computer Science, Fall 2013)
Design and Analysis of Algorithms (AUEB, MSc in Computer Science, Fall 2013)
