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:

  • Inverse problems solving by promoting a sparse signal models.
  • 1-bit and high-resolution Quantized Compressed Sensing (QCS).
  • Quantized random projections: theory and application (e.g., for Physical Unclonable Function - PUF)
  • Applied mathematics for Optics (Deflectometry), Astronomy (Radio-Interferometry) and biomedical applications (X-Ray Imaging).
  • New models for sensor design (e.g., cameras, optical sensors, tomography, hyperspectral imaging).
  • Representation of data on "non-conventional" spaces (e.g., sphere, manifolds, or graphs).
