Presentation

**Working on ecology, diversity and evolution of plants, I’m interested by wild life and conservation in general. In my other life I’m living with my wife and my son in Marseille, also climbing, hiking and reading a lot.** Cursus • 2013 : Habilitation à Diriger des Recherches : « Situation des structures de diversité génétique dans l’enquête écologique », Aix-Marseille Université • 2002 : Maître de conférences de l’Université Paul Cézanne, Aix Marseille III • 2002 : Attaché temporaire de l’Université Rennes I (ATER) • 2001 : Thèse de l’Université Rennes I, mention Biologie : « Contexte phylogénétique et conséquences génomiques de l’hybridation et de la polyploïdie : Les enseignements d’une jeune espèce, Spartina anglica C.E.
