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.- Evolution of the protosolar disk and planetary formation.- Advancements of techniques for geochemical and isotopic analyses.
