Self-introduction
I use laser light and synchrotron radiation to explore invisible microscopic changes occurring inside materials. When environments such as temperature, magnetic field, and electric field are controled, materials can exhibit unexpected behavior. By uncovering the reasons behind these changes, I aim to deepen our understanding of materials and discover the fascinating properties of materials yet to be seen.
