the finance chair of ACM MobiCom '13, the co-chair of ACM MobiSys HotPlanet '12, the general chair of ACM MSWiM '11, co-chair for
ACM MobiCom CHANTS '11, honorary chair for IEEE IWCMC '11, co-chair for ICST AdHocNets '11, poster co-chair IEEE SECON '11,
general chair for ACM IWCMC '10, track chair for IEEE MASS '10, track chair, poster & Ph.D. forum chair for IEEE ICNP '09, local
arrangements chair for IEEE ICNP '08, IEEE Infocom Global Internet (GI) workshop '08, co-chair of IFIP/IEEE MMNS '06, and vice-chair
for IEEE ICPADS '06, and IEEE HiPC '07. He was ACM SIGMOBILE workshop coordination chair (for
MobiCom, Mobihoc, Mobisys, Sensys) ('06-'11). He served on numerous committees of IEEE & ACM conferences on networks.
He is a Fellow of the IEEE (IEEE-Computer Society, IEEE-Communications Society), and
a Distinguished Scientist of the ACM (ACM SIGCOMM, ACM SIGMOBILE)

- - Quick Recent News:
- - Named IEEE Fellow "for contributions to routing protocol design and mobility modeling"! Less than 0.1% of the IEEE voting members are
selected for this grade. (more on IEEE website). This recognizes research work performed by the excellent
students, collaborators and colleagues with whom I have been fortunate to work, and who have supported my work, over the past two decades.
It is a testament to the great impact our work has had on the field of computer networks and mobile networking.
