Stéphanie Chaillat-Loseille

Senior Research scientist

(Directrice de recherche)

I am a senior research scientist at CNRS working at the interface between computational mechanics and applied mathematics. My research is driven by realistic physical phenomena and industrial challenges. I develop fast algorithms and numerical methods to study large-scale wave propagation problems, such as acoustic and seismic wave propagation. In recent years, I have collaborated closely with Naval Group on topics related to underwater acoustics. See the Collaborations and Outreach pages for more details and examples.
Since 2025, I have served as Deputy Director of the POEMS laboratory, a joint research unit of CNRS–INRIA–ENSTA. From 2022 to 2024, I was an Adjunct Faculty member in the Department of Geophysics at Stanford University. Prior to joining CNRS, I worked as a Postdoctoral Associate at the College of Computing at Georgia Tech. I earned my PhD in Mechanical Engineering from École Polytechnique in France.

My expertise lies in the development of numerical methods for partial differential equations and ordinary differential equations, with a focus on fast algorithms and efficient (parallel) programming. I am passionate about pushing the boundaries of computational science and continuously expanding my research horizons. Currently, I am exploring how machine learning can accelerate the solution of wave propagation problems, aiming to harness its potential for improving computational efficiency and accuracy in complex simulations.

I am part of the editorial board of the journals Advances in Computational Mathematics (ACOM) and Journal of Theoretical, Computational and Applied Mechanics (JTCAM).
Following my investement in JTCAM, I have joined the Open Science Advisory board of Institut Polytechnique de Paris.
Since 2024, I am the vice-president of the French Computational Structural Mechanics Association CSMA.
