Takemi Kato is a postdoctoral researcher at the Advanced Institute for Materials Research, Tohoku University. He received his Bachelor, Master and Doctor of Science from Tohoku University in 2019, 2021 and 2024, respectively. He joined the group led by Professor Takafumi Sato in 2018, and started his work using angle-resolved photoemission spectroscopy which is an experimental technique to directly observe electronic states of materials. During his doctor program, he mainly studied electronic structure of newly discovered kagome superconductors, especially focusing on the electronic nature of charge-density wave.
