Current Research
The geochemistry is the one of the key research field to derive the direct “evidence” of the growth history of the Earth and the Solar System. We are trying to understand the early sequence of the solar system, meteorites, planetesimals or the Earth’s core, and also to decode the crustal growth sequence and the origin and evolution of the life through the elemental and isotopic analyses of various samples including rock, mineral, fluid, and even for biochemical tissues. To achieve this, we are developing a state-of-the-art technique for the elemental analysis using the high power lasers and the mass spectrometry. Among the technique, combination of the femtosecond laser and the ICP-mass spectrometry has a potential to become a significant and the most sensitive tool for the elemental and isotopic analyses for various solid samples. New analytical techniques can become a major tool to open up the non-traditional research field. Here you can find the answer.
