This project has been fundedin 2016 by the CEA Fundamental Research Division (DRF) for 2 years to foster  collaborations between CEA research scientists and engineers working on biomedical imaging (Magnetic Resonance Imaging or MRI) at NeuroSpin (Team leader: Philippe Ciuciu) and on astrophysics at the CosmotStat Lab (Team leader: Jean-Luc Starck) within the Astrophysics Department) on Compressed Sensing (or Compressive Sampling, see here for details about CS).

On the one hand, the NeuroSpin team has reached a scientific expertise in Compressed Sensing for MRI, especially in the design of efficient under-sampling schemes of the Fourier domain (also termed k-space in the MRI community).  This work is also the result of a fruitful collaboration with mathematicians from CNRS in Toulouse, noticeably Pierre Weiss (ITAV) & Jonas Kahn (IMT).

On the other hand, the CosmoStat team  is focused on computational cosmology. They develop and apply new methods from statistics, signal processing, and compressed sensing to cosmology and other fields. The main CosmoStat research areas are:
