Structural knowledge is essential for understanding physical properties and tailoring applications of condensed matter. However, understanding of atomic structures is still not enough for aperiodic crystals, especially for quasicrystals. One of the subjects of my current intensive research is the structure determination of quasicrystals and structurally complex alloy phases including approximant crystals to quasicrystals using laboratory x-rays, synchrotron x-rays and neutrons. I also develop structure determination method of aperiodic crystals. As the future perspective of my research, I intend to understand not only static structure, but also dynamical structure of non-periodic ordered materials.
