Adrien Busnot Laurent

Adrien Busnot Laurent is a permanent researcher (Chargé de recherche) at INRIA Rennes in the MINGuS (Multi-scale numerical geometric schemes) team. He previously held a postdoctoral position at the University of Bergen working on the CODYSMA project (Computational Dynamics and Stochastics on Manifolds) with Hans Z. Munthe-Kaas, and completed his Ph.D. in Mathematics at the University of Geneva under Gilles Vilmart's supervision.

His research focuses on numerical methods for stochastic differential equations, with particular emphasis on geometric numerical integration, algebraic structures in numerical analysis, and numerical integrators on manifolds. He has made significant contributions to the theory of exotic aromatic B-series, which provide a framework for analyzing high-order integrators for ergodic stochastic differential equations.

Adrien's publication record shows consistent high-impact contributions in top journals including Foundations of Computational Mathematics, SIAM Journal on Scientific Computing, and Forum of Mathematics, Sigma. His work bridges theoretical mathematics with practical numerical algorithms, with applications in molecular dynamics and statistical physics.

He has been recognized with the SWICCOMAS prize 2022 and the Henri Fehr prize for his Ph.D. thesis. As PI of the ANR JCJC project MaStoC, he leads research on manifolds and stochastic computations, with plans to open postdoc positions from September 2026.

Adrien is actively involved in the academic community, co-organizing conferences including GeoStoch 2026 and CANUM 2026, and organizing a research seminar in applied mathematics at ENS Rennes. He also participates in outreach activities and supports diversity in mathematics.
