My research interest is focused on the application of distributed algorithms to solve resource allocation problems in networked environments. Recently I have undertaken research on networks monitoring strategies, anomaly detection and networks performance estimation using signal processing techniques for problems in intelligent transportation systems and wireless sensor networks. Another area of interest is on distributed resource allocation in dynamic topology networks and fair and efficient resource allocation in power systems environments as well as in IP environments. I am also interested in novel information and communication technology applications for power systems. My research in the past covered the area of robust communication system design; revenue management in multiservice systems and communication networks, and the application of intelligent agent systems and distributed algorithms to solve telecommunication networks problems.
