Welcome !

I am a CNRS research scientist at CRAN since 2019. I am 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 bivariate signal processing, polarimetric imaging, quaternion-valued signal processing, with applications to underwater acoustics and gravitational waves in astrophysics.

Wanna join our group? We have currently a 12-month postdoctoral researcher position available on Geometric Bayesian inference for bivariate signals, starting anytime in 2023. See also this master internship position.


Mar 17, 2023 Two papers accepted at ICASSP’23. See you in the greek island of Rhodes in June!
Feb 8, 2023 New master internship position available on Tensor Learning for Color and Polarimetric Images, starting March 2023.
Nov 1, 2022 New postdoctoral position available on Geometric Bayesian inference for bivariate signals, starting Jan. 2023!
Oct 1, 2022 New Ph.D. student Saulo Barreto is starting, with S. Miron and I on low-rank tensor representations for polarimetric data. Welcome Saulo!
Sep 20, 2022 I’ll be visiting Julien Bonnel at WHOI, USA for two weeks
