The Murchison Medal, which recognises geologists who have contributed significantly to 'hard' rock studies, is awarded to Professor Janne Blichert-Toft, CNRS Research Director at the Ecole Normale Supérieure de Lyon, France. As geochemist, she specialises in the use of isotopes with applications in understanding planetary mantle-crust evolution, as well as the chemical composition of matter in the Universe.
Janne Blichert-Toft is specializing in the use of isotopes with applications in understanding planetary mantle-crust evolution, as well as the chemical composition of matter in the universe. To further this research, Blichert-Toft has developed techniques for high-precision Isotope-ratio mass spectrometry measurements.
