My research activities focus on modeling and analysis of delay tolerant and mobile social networks, in which I work on proposing and optimizing algorithms used in DTNs, mathematical modeling and performances analysis. I work on game and control theories applications, trust and reputation management in contexts involving diverse rational agents with conflictual interests as well. I have been serving as a reviewer for several international conferences and journals such as IEEE Transactions on Wireless Communications, Impact factor : 4.951, ISSN :1558-2248.
