This project was funded in 2016 by the CEA Fundamental Research Division (DRF) initially for 2 years to foster collaborations between CEA research scientists and engineers working on biomedical imaging (Magnetic Resonance Imaging or MRI) and astrophysics.

COSMIC is led by NeuroSpin (Team leader: Philippe Ciuciu) and the CosmotStat Lab (Team leader: Jean-Luc Starck) of the Astrophysics Department. The main topic of interest being Compressed Sensing (or Compressive Sampling, see here for details about CS). Given its success, the project has been renewed for the 2018-2020 period.

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).

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:

• • Statistics & Signal Processing: Develop new methods for analyzing astronomical data, and especially in cosmology (PLANCK, Euclid, etc.) where the needs of powerful statistical methods are very important.
  • Cosmology: Analyse and interpret data. This includes CMB, weak lensing, and other fields such as galaxy clustering and BAOs.
