Specialized in X-ray imaging (micro and nano-tomography, single-distance phase-retrieval) and powder diffraction (XRD-CT), my research interest focuses on developing new imaging methods to characterize materials and understand their behavior.

More particularly, I am in charge of the TOMCAT nanoscope. This full field imaging setup allows to get a spatial resolution around 150 nm between 10-18 keV on sample of 50µm2. The setup can be used for absorption or phase contrast imaging. In this case, Zernike phase contrast is exploit to enhance contrast for phase objects.

As local contact, I collaborate with international researchers material sciences related (e.g. nuclear materials, explosives identification, cement hydration , ...) as well as paleontology (hominid dental microstructure , fossil as rock slabs) and biology (heart).


During my PhD at the INSA de Lyon, I studied the physical properties of materials in order to discriminate explosive to common materials (see here). After four years in the X-ray imaging group at the European Synchrotron Radiation Facility (Grenoble, France), I joined in April 2014 the Phase Contrast core of the CIBM based at the TOMCAT Beamline.
