I obtained a Ph.D. degree in Quantum Engineering Design from Graduate School of Engineering, The University of Osaka in September 2021. Under the supervision of Prof. Tamio Oguchi, I investigated the simultaneous migration of small polaron and Na ions cathode materials using the density functional theory (DFT) simulation method. From October 2021 to March 2024, I worked as a National Institute for Materials Science (NIMS) Postdoc Researcher in the Tateyama group, studying the electronic-ionic conductivity correlation and the surface degradation in the cathodes for Li-ion battery. Since April 2024, I have been a specially appointed assistant professor in the Tateyama-Ando group at Institute of Science Tokyo. I am currently focusing on the fundamentals of thermodynamics and, electrochemistry of electrode materials for Na-ion batteries.
