Franck completed MSc at Ecole Normale Superior in Lyon. Stephane Guillot and I jointly supervised his MSc thesis project, origin and tectonometamorphic evolution of mafic sediments in the central Quetico metasedimentary belt, western Superior Province of Canada. He concluded that the Quetico belt represents an accretionary prism developed south of the Uchi volcanic arc in late Archean time. He calculated the paleo-geothermal gradient of the late Archean accretionary wedge. The results are summarized in our paper in Precambrian Research.

After MSc, he completed PhD at the University of Paris.

After PhD, he was working for several Canadian Mining companies (Odyssay Resources, and Eastmain Resources), now moved to Newmont based in Perth, Western Australia.
