Research Areas: Petrogenesis of igneous rocks; U-Th disequilibrium; ND, SR, Pb and O isotope and trace element geochemistry; chemical geodynamics; East Asian geology; time scales of magma chamber processes; volcanology; quantitative geochemical modeling; mass spectrometry, including thermalionization, secondary-ionization, and plasma-ionization mass spectrometry.

More specific research interests are given as follows. (1) Petrology and Chemistry of the Earth and Planets The goals of this study are to achieve a better understanding of the differentiation and chemical evolution of the Earth and other planets, the geochemical aspects of crust-mantle interaction, the dynamics and evolution of magma systems, and the formation of the crust and the process of weathering, through the integrated study of isotopic compositions (Sm-Nd, Rb-Sr, Lu-Hf, and U-Th-Pb isotopic systematics) and traceelement concentrations and ratios in igneous, sedimentary, and metamorphic rocks.
