about me

I completed my Ph.D. in January 2018 on time parallelization strategies for numerical simulation of turbulent flows at ISAE-SUPAERO and CERFACS (Toulouse, France), for which I was awarded the Paul Caseau Prize in 2019. After that, I worked for three years in the Section of Mathematics at the University of Geneva (Switzerland) as post-doctoral assistant with Prof. Martin J. Gander, followed by a post-doctoral position at the Math Institute of TUHH with Prof. Daniel Ruprecht. Since 2022, I am engaged in programming teaching at TUHH, and joined the ACPS Institute in March 2026 as Senior Researcher.

For my research, I works in the field of computational mathematics and high-performance numerical methods, with a particular focus on numerical analysis, time integration algorithms, and parallel computing for evolving dynamical systems. I specialized in Parallel-in-Time algorithms and Spectral Deferred Correction methods, while building in parallel practical experience on web tools development (API, back-end & front-end).
