Details for: Janne Blichert-Toft


Janne Blichert-Toft obtained her PhD in earth sciences at the University of Copenhagen in 1993. After a Marie-Curie post-doc she joined the CNRS in 1997 and became Director of Research in 2002 working at the Ecole Normale Supérieure in Lyon. Janne is a geochemist specializing in radiogenic isotopes with applications to geochronology, terrestrial and planetary mantle-crust evolution, crustal growth, early Earth geodynamics, cosmochemistry, and archeometry, and also develops techniques for high-precision isotopic measurements. In particular, she pioneered the application of hafnium isotopes by MC-ICP-MS to the evolution of the Earth and the early solar system. Janne is currently Editor of G-Cubed and Geochemical Perspectives and Associate Editor of Geochimica et Cosmochimica Acta, she is a Fellow of the American Geophysical Union, the Geochemical Society, and the European Association of Geochemistry, and recipient of the CNRS Bronze and Silver Medals, the Prix Etienne Roth of the French Académie des Sciences, and the Steno Medal of the Danish Geological Society.
