Julien Bigot is a permanent CEA computer scientist at Maison de la Simulation where he leads the Science of Computing team. His research focuses on programming models for high performance computing. He is especially interested in the question of separation of concerns between the simulated domain-specific aspects and optimization aspects. Julien tries to concretize his research into production-level software like the DDC, Deisa, or PDI libraries whose development he started, or Kokkos, a project of the Linux Foundation originating from the U.S. DOE. He also tries to apply these libraries in production into real codes like the Gysela code, for example.

Julien leads the CExA project that contributes to the Kokkos ecosystem. He also takes part in the NumPEx program, which intends to contribute to the French Exascale software stack.
