I am a PhD student at the Inria team CORSE (Compiler Optimization and Runtime SystEms) and the Université Grenoble Alpes.
I work on performance debugging, that is analysing an applications performance and finding hotspots and bottlenecks.
The main focus of my work has been on:
- Disassembling optimized binaries & re-constructing higher-level information.
- Program instrumentation using dynamic binary translation with tools such as QEMU and DynamoRIO.
- Performance evaluation of modern x86 & ARM CPUs, as well as reverse engineering parts of their instruction pipelines.
- Work with the machine description system of the LLVM compiler infrastructure (tablegen).
Experience
Inria / Université Grenoble Alpes
Teaching assistant
class: Programming Language Semantics and Compiler Design for Yliès Falcone
Colorado State University
Visiting researcher
Worked on using techniques from polyhedral compilation to give optimization feedback to progammers.
PPoPP 2018 conference
Web Chair
Maintained the conference website & program with joint conferences (CGO, HPCA, CC)
Colorado State University
Visiting researcher
Worked on reverse engineering performance aspects of modern OoO x86 & ARM CPUs with Louis-Noel Pouchet.
Inria / Université Grenoble Alpes
Teaching assistant
class INF 302: Langages & Automates (formal languages & automata) for Yliès Falcone
PhD student in the CORSE team
Advisor: Fabrice Rastello
Co-advisor: Ylies Falcone
Work on performance debugging & performance analysis.
Work with a dynamic binary instrumentation framework on top of the QEMU CPU emulator for re-constructing call graphs & inter-procedural loop forests from optimized binaries as well as tracking data dependencies. Using this information code transformations are proposed using a polyhedral optimizer.

Research Engineer in the CORSE team
Worked on the TIREX project, a machine-code level compiler IR exchange format.
Wrote LLVM based tools for instruction level code analysis & hybrid (both static & dynamic/instrumentation based) alias analysis.
