About me

I received Supélec (France) engineering degree in 2015, and the master of science in Electrical and Computer Engineering from Georgia Institute of Technology (USA) in 2016. From 2016 to 2019, I was a PhD student in the CosmoStat group at CEA Saclay (France), where I worked on the optimization framework for sparse blind source separation, as well as non-linear component separation. I then went for one year in Mons (Belgium) where I worked, as a post-doctoral researcher, on the extension of Nonnegative Matrix Factorization to Linear-Quadratic mixture unmixing.

I am currently an Assistant Professor (maître de conférences) at Télécom Paris (France), in the IMAGES group.

Research interests

• Sparse Blind Source Separation 

• (Provably robust) Nonnegative Matrix Factorization

• Non-linear component separation methods (with sparsity or nonnegativity constraints)

• Optimization: hyper-parameter choice and scalable multi-convex optimization

• Deep learning for inverse problems and unrolling techniques

• Hyperspectral imaging
