Research Field

Geochemistry and cosmochemistry

Current Research

My research centers around the application of geochronology, geochemistry and isotopic study to issues in Earth and planetary sciences. In particular, I am interested in:
- Origin and growth of the Earth's continental crust.
- Early Earth evolution.
- Effects of crustal evolution on Earth's surface environment.
- Formation and chemical differentiation of the terrestrial planets.
- Advancements of techniques for geochemical and isotopic analyses.
