Research Interests
- Early Earth crust-mantle differentiation, core-mantle segregation using high-precision measurements of short-lived W, Nd isotopes and long-lived Lu-Hf, Sm-Nd isotopes
- Early Archean tectonic regimes using Si isotopes and high-precision High Field Strength Element abundances
- Initial Hf, Sr isotopes in accessory minerals (zircon, apatite) using in-situ and bulk dissolution methods
- Precambrian low-temperature systems especially isotope compositions of seawater
