Opportunities for students

• Superbe sujet de thèse 2013 au frontière de la recherche fondamentale et appliquée (avec en prime un séjour en Nouvelle-Zélande !) : Modélisation numérique de l’impact géomorphologique des grands tremblements de terre sur la dynamique des rivières : application à la faille Alpine (Nouvelle-Zélande). Contactez-moi pour plus d’infos.

  

  Sujet Thèse 2013

• Marie-Curie individual fellowships : if you are a young post-doc researcher interested in working with our team, we can prepare an application for these fellowships. We have a significant experience on these projects and had a couple of successful results !
