The first collaborator is of course... my PhD advisor! He has never been really member of the FEMTO-ST institute, since he left the academia (for a brilliant continuated professional carrier in the private sector), before the institute creation in 2004. He was, and still is, a great mentor for me from a professional viewpoint, but additionally to this he is also an estimated and very good friend. I hope he won't be too embarrassed to occupy the first place here, but he is definitely the first guilty person for this position.
