CNRS, CRAN, Université de Lorraine, Nancy, France.
Welcome !
I am a CNRS research scientist in Nancy, France. Im a member of the SiMul research group, the multidimensional signal processing research group in the BioSiS department at CRAN.
I develop signal processing theory and methods to leverage polarization properties in physics, focusing on interpretable, geometric and algebraic approaches.
My research interests include phase retrieval, bivariate signal processing, polarimetric imaging, quaternion-valued signal processing, with applications to physical sciences.
open positions
Several positions are currently open for Spring 25 (check out instructions in pdfs on how to apply)
- 6 months M2 internship in Nancy, Acoustics and Signal Processing, with Julien Bonnel (WHOI)
- 6 months M2 internship in Grenoble, Geometric phase of multivariate signals with Nicolas Le Bihan and Pierre-Olivier Amblard.
ongoing research projects
I am currently involved in the following research projects
- ANR JCJC ATEMPORAL, 2024-2027: Algebraic and Tensor Methods for Polarimetric Phase Retrieval (PI)
- ANR PRC RICOCHET, 2022-2026: Bivariate signal processing: a geometric approach to decipher polarization (Leader for CRAN)
