Research Interests


I am a graduate engineer of the ENSIIE (Ecole Nationale Supérieure d'Informatique pour l'Industrie et l'Entreprise).

I did my thesis from 2005 to 2008 in Orange Labs in Paris, and in the University of Angers. My advisors were Jean-Luc Lutton (Orange Labs) and Jin-Kao Hao (LERIA, University of Angers). My thesis deals with the interdomain and intradomain routing in core networks, and more precisely on iBGP. In iBGP, route reflection may lead routing inconsistencies. In this work, I present an approach to detect bad iBGP network design and to compute robust and valid iBGP network topologies. I also propose a modification of the iBGP route spread rules that fixes iBGP routing issues, which has led to a first patent written with Bruno Decreane. During my thesis, Anthony Lambert and me have written another patent which propose efficient timers that enhance routing protocols convergence, including BGP.

From 2011 to 2014, I am a research engineer at the University Pierre et Marie Curie (UPMC/LIP6). I'm also affiliated to the Laboratory of Information, Networking and Communication Sciences (LINCS). I'm working on several projects including libparistraceroute, a library designed to develop active measurement tools, and TopHat, a tool providing Internet measurements.

Since March 2015, I'm a researcher at Nokia Bell Labs (ex-Alcatel-Lucent) in the mathematics department.
