Vincent has been working as a post-doctoral researcher at the University of Illinois at Urbana-Champaign (USA) since he obtained his PhD at the Paris observatory (France) in november 2014. His main scientific interests are related to cosmology and general relativity. He his particularly interested in the study of relativistic effects at cosmological scales using high performance simulations run on supercomputers. Because these simulations rely on tree data structures, he started investigating ways to optimize them. He now leads a research team working on tree data structures with main applications in simulations, machine learning, and data science. He also participates into the C++ standardization process and regularly submits proposals to improve the C++ language.
