I am a full-time researcher at Inria.

I am based in Strasbourg, in the Camus team, part of the ICPS team from the iCube lab.

I also work closely with the DeepSea project at Inria Paris.

My research interests span from programming languages to mechanized proofs.

Selected papers:

Program verification
Multicore programming
  • Granularity control for nested parallelism: provably efficient granularity control (PPoPP'19).
  • Strict-binning PIC: efficient particle-in-cell simulations using chunk sequences (Euro-Par'18).
  • Heartbeat scheduling: provably-efficient scheduling for nested parallel programs (PLDI'18).
  • DAG calculus: a unifying model for describing high-level parallel constructs (ICFP'16).
  • Granularity control: using asymptotic complexity annotations to predict tasks size (JFP'16).
  • Parallel DFS: a work-efficient algorithm for parallel unordered depth-first search (SC'15).
  • Chunked sequences: an efficient sequence data structure for parallel algorithms (ESA'14).
  • Work stealing with private deques: scheduling without concurrent work queues (PPoPP'13).
Formal metatheory in Coq

I design interactive challenges for the Concours Castor Informatique, french edition of the Bebras contest. It aims at raising children's interest for computer science.
More than 600,000 students participated in the contest in November 2017.
