I am working in Raymond Namyst's Runtime Inria Team-Project. My primary research interests are:

• I/O in multicore and NUMA hierarchical machines (with Stéphanie Moreaud, former PhD student), especially within the knem and hwloc projects.
• Modeling modern hierarchical and multicore platforms (with Bertrand Putigny, PhD student).
• Memory management and migration for OpenMP threads scheduling over hierarchical architectures (with François Broquedis, former PhD student).
• High performance communication, within CCI and Open-MX projects.
