My research activities mostly concern gamma-ray astrophysics and Active Galactic Nuclei.

My early work in the field was carried out during my PhD, with a 2-year stay at the Whipple Observatory in Arizona. My technical and analysis work made possible the discovery of the first very-high-energy extragalactic source, Markarian 421. During my post-doc in France at the LLR laboratory, I worked on the conception and the construction of the Imaging Cherenkov Telescope CAT (Cherenkov Array at Themis), both introducing Winston Cone Light collection elements for imaging gamma ray astronomy, and working on the user interface for the telescope control and on the data analysis and physics.

Since 1996, I am a permanent researcher of the Centre National de la Recherche Scientifique (CNRS) working at the Astroparticule et Cosmologie (APC) laboratory in Paris.

During the period 1999-2003 I was the technical coordinator of H.E.S.S.-I camera, and in 2001-2013 PI of H.E.S.S. France. I was Deputy spokesperson of H.E.S.S. from 2003 to 2013, and responsible for the H.E.S.S. AGN Working group up to the end of 2012. My hardware activities in H.E.S.S. have been related to the construction of testbench & testing of the ARS0 analogue memories, and in the conception of the H.E.S.S. Winston cones and their testbench.

I am currently on a one-year mission to Linnéuniversitetet, campus Växjö.

My current work in the Cherenkov Telescope Array concerns the "Array Trigger & Clock distribution" and I am Quality Manager of the project.
