  2012 - 2013 Development of a 2D compression cell to determine the onset of rigidity and mobility in granular media using photoelastic discs.
  
  Skills: Automatization of data acquisition from HD cameras and pressure sensors using LabVIEW. Detection of particles from 2D pictures using C/C++ programs

• Max Plank Institute for Dynamics and Self-organization - Researcher

  2009 - 2012 Experimental study of the phase diagram of granular media. Determination of the force needed to initiate a displacement in a granular bed as a function of its packing fraction. Measurement of the variation of the local packing fraction and of the particles displacement when the granular media is sheared using X-Ray tomography.
