Thèmes de recherche

  • Gianreto Manatschal was born in a small rumantsch village (Sta Maria/Val Müstair) in the Alps of SE Switzerland. He received his PhD in geology from the ETH Zürich, Switzerland in 1995. After postdoctoral appointments at the Danish Lithosphere Centre and at ETH Zürich, he moved to Strasbourg (France), where he became full professor in tectonics at the Ecole et Observatoire des Sciences de la Terre in 2003. His major research interests are related to the formation and reactivation of rifted margins in the Atlantic and Alpine Tethys domains. He participated on ODP Legs 173 and 210 at the Iberia and Newfoundland margins and worked in the Alps, Pyrenees and at many rifted margins in research projets and/or with industry. He is head of the geology group at the University of Strasbourg and supervised or co-supervised 47 Master students, 35 PhD students and 15 Post Docs. He is involved in several research projects financed by national science foundations and companies, holds (together with Nick Kusnir) a consortium with 13 companies (M6 consortium) was and is PI of several big research projects. He is married and father of 3 children.
