room: B206, II floor

I have a background in the design and analysis of efficient heuristics for NP-hard and on-line optimization problems, with an emphasis on the application of probabilistc and randomized techniques. My current research interests include the design and analysis of algorithms for Web information retrieval and data mining and the modelling and analysis of dynamic and distributed processes and algorithms over large complex systems. This research activity has occurred and occurs especially within the framework of european research projects that have involved or involve prominent universities and research centers.
I regularly serve in the program committees of the most prominent conferences in the area
