Lucas Perrin
Since October 2024 I am a Post-Doctoral researcher at Universität Konstanz within Stefan Volkwein's Arbeitsgruppe Chair for Numerical Optimization.
Part of my work is in collaboration with Virtual Vehicule.
Previously, from September 2021 to August 2024, I was a Ph. D. candidate at INRIA Paris (ANGE team) and Laboratoire Jacques Louis Lions (Sorbonne Université) under the supervision of Julien Salomon.
Research areas
My research lies in numerical analysis, mainly reduced-order modelling, parallel (in time) computing and data assimilation (observation and control of dynamical systems). I am also deeply interested in computational fluid dynamics, HPC, and machine learning.
Here is my CV in English.
Seminars
Co-organiser of the research school IMPDE 23 with Liu-Di Lu and Bastien Chaudet-Dumas
Workgroup
From April 2022 to May 2023, I co-organised the Ph. D. Seminar (GTT) of the LJLL.
