I am working on the creation and development of functional inorganic compounds using various synthetic methods such as thin-film synthesis, high-pressure synthesis, and high-quality single-crystal synthesis. I am also focusing on novel types of elementary excitations in condensed matter and solids (e.g., magnetic monopole in spin ice materials).
