Janne Blichert-Toft

Janne Blichert-Toft is a geochemist, 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.
