My research interests revolve around:
- Bayesian inference & Markov models
- Sparse (off-the-grid) analysis
- Time-frequency transforms properties
with applications in:
- Fluorescence and tomographic diffractive microscopy
- Remote sensing images
- Physiological signals
- Astronomical images
- Medical images
- We uploaded a preprint about the morphology of grapevine wood together with a 4771-image database and the image processing code.
- We recently uploaded a preprint about the sampling of Markov random Fields ! See here.
- With Pierre-Antoine Thouvenin, we hosted a GDR IASIS thematic day on Bayesian inference for inverse problems, the 11th of June 2026. See the GDR IASIS meeting page. Stay tuned for a second edition !

As principal or co-principal investigator I am involved in the following projects:
- (2024 - 2028) ANR PRC CAMoMill (Computer Assisted Multimodal Microscopy for Quantifying Molecular Diffusion in Cells) leading the work package on inverse problems for multimodal microscopy and with Aymeric Leray as PI.
- (2023-2026) IMPT ECTHAR (Estimating Cloud Top Height with Active and lidaR measurements) as PI with the LMD.
- (2024-2025) OCARINA (Off-the-grid curve reconstruction: applications in remote sensing and phytopathology) project through a innovative and risky UHA project.
I am also involved in the following projects:
- (2025-2029) ANR PRC TIPHAINE (Time-frequency analysis of Interference in complex signals) with Ali Moukadem (IRIMAS), Sylvain Meignen (LJK), and Adrien Meynard (ENS Lyon).
- (2023-2025) Vineside, through an interlal call Projet de recherche within UHA, with Romain Pierron and Célia Perrin.
