Biography

I am a permanent research scientist in the Planète project-team at INRIA, Research Centre Sophia Antipolis – Méditerranée, since March 2002. I got my Electrical and Electronics engineering degree from the Lebanese University of Beirut in 1997, and my Master and Ph.D. degrees in Networking from the University of Nice - Sophia Antipolis in 1998 and 2001. My Ph.D. was done in the Mistral project-team at INRIA Sophia-Antipolis under the direction of Eitan Altman. From April 2001 to March 2002, I was with the LCA department at EPFL-Lausanne for a post-doctoral position (with a grant from Sprint Labs working in the group of Patrick Thiran), and from March to August 2004, I was a visiting faculty member at Intel Research Cambridge working in the group of Christophe Diot on traffic monitoring. My main research interests are Internet measurements and traffic analysis, content-centric and delay-tolerant networking, and performance evaluation of computer networks. I am senior member of the IEEE and member of the ACM.
