Ph.D. Defended!

I am happy to share that I successfully defended my Ph.D. thesis, “Understanding Linux Kernel Scheduling Bottlenecks,” on June 3, 2026, at Inria Rennes.

This defense marks the end of an intense and rewarding research journey conducted at Inria Rennes, IRISA, and the University of Rennes. My thesis provides a comprehensive study of limitations in Linux kernel scheduling mechanisms and asynchronous execution APIs, and analyzes their impact on the performance of multithreaded applications and the energy efficiency of Intel heterogeneous CPUs.

I am deeply grateful to my supervisors, David Bromberg, Julia Lawall, and Djob Mvondo, for their guidance, trust, and support throughout this Ph.D. I also sincerely thank my committee members: Gaël Thomas and Jean-Marc Menaud for reviewing the manuscript, and Bernabé Batchakui and Camélia Slimani for serving as examiners and for the insightful discussion during the defense.

This Ph.D. has been a challenging but formative experience. It strengthened my interest in operating systems, performance analysis, kernel-level engineering, and the design of efficient computing systems.

I am now looking forward to the next step: bringing this expertise to industry, ideally in an R&D systems engineering role focused on operating systems, performance, infrastructure, networking, or low-level software systems.
