I am proposing several M2 internship and PhD subjects, and I look for candidates (see below)
Job offers:
PhD subject about hyperspectral unmixing with Plug-and-Play methods
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. I work in two main applicative fields: remote sensing and medical imaging. I focus on interpretable deep learning methods, with an emphasis on several aspects: 1) interpretability of the neural architectures ; 2) uncertainty quantification ; 3) controlled synthetic training set generation.
Research interests
Deep learning for inverse problems (including in particular works about deep unrolling techniques)
Remote sensing (hyperspectral imaging and synthetic aperture radar) and medical imaging (tomosynthesis, bioluminescene imaging)
Uncertainty quantification
Non-linear component separation methods
Synthetic training set generation
Blind Source Separation: sparsity-based approaches and (provably robust) Nonnegative Matrix Factorization
Optimization: hyper-parameter choice and scalable multi-convex optimization
