PhD research:

I achieved my PhD thesis (Dec. 2014) on Compressive Fluorescence Microscopy for biological imaging. This work is an implementation of the recent « Compressive Sampling » (CS) theory that leverages compressibility. Based on a paradigm shift in signal processing our application shows:

  • a unique scheme for 2D imaging using far less measurements than traditional Shannon-Nyquist sampling theory,
  • an extension to Hyperspectral Imaging scheme where multidimensionality introduce high redundancy that greatly increase compression ratio as the signal becomes sparser.

Another part of this work consisted in exploring the possibility to use Compressive Sampling theory for Single Molecule Localization Microscopy (SMLM) at high densities for super resolution microscopy (PALM/STORM). Using this technique, it is possible to drastically reduce the frame stack size by increasing the number of molecules within a region of interest, despite most of molecules are overlapping (because of the point spread function). Thus, one can expect to reconstruct super resolved microscopy images while strongly reducing acquisition time (live imaging).

Former projects:

I have been deeply involved in several projects dedicated to ultra intense laser-matter interactions in the framework of fast ignition (FI) approach to inertial fusion. The lack of experimental data has motivated various studies in the High Energy Density Physics (HEDP), especially in the field of Warm Dense Matter (WDM) where there is a critical need to ensure atomic physics models and simulations tools. I contributed on multiple experiment campaigns where we investigated coupling efficiencies of high-contrast laser irradiation to nanofabricated targets through 2D Kα fluorescence imaging and spectroscopy. These experiments had been performed on both LLNL (CA, USA) and LULI (Paris, France) facilities (respectively PW and TW lasers).
