Well, here is "yet another" scientific homepage ;-)
I collect in these pages data and recent news about my research and interests. These are also the result of collaborative works with other researchers. Feel free to discover these topics by browsing the menu here on the left, or on on Google Scholar.

Main fields of interest:

  • Compressive sensing: theory and applications
  • Computational imaging, with applications in optics, astronomy, and hyperspectral and biomedical imaging
  • Regularized inverse problems solving, and data restoration problems.
  • Low-complexity representation of data (such as sparse or low-rank models, wavelets, spherical data).
  • Quantized and one-bit compressive sensing.
  • Compressive Learning and compressive density estimation
