About me

I am an associate professor (Maitre de conférences) in signal processing, image processing and machine learning at Toulouse-INP - ENSEEIHT. I am also part of the Signal and Communication (SC) at the Institut de Recherche en Informatique de Toulouse (IRIT).

In 2020, I graduated from INSA Rouen with an engeenering degree in applied mathematics, and I have obtained my PhD from Bordeaux university in 2023. My thesis topic was on Image restoration with deep generative models.

I have worked as a post-doctoral researcher at the MAP5 lab of université Paris-cité, and at the research center on computer science, signal processing and automatics of Lille (CRIStAL).

My research interests focus on the resolution of challenging inverse problems using data-driven methods. In particular, I work on the developpement of hybrid methods, which incorporate deep generative methods into a classical bayesian framework. I have worked on applications in imaging inverse problems and in cosmology.
