I am an Astronomer and exploring galaxy formation and evolution and the early universe with observational data. In particular, I study the relationship between galaxies and the interstellar, the circumgalactic, and the intergalactic medium in terms of gas cycling. I am also interested in the application of machine learning techniques in astronomical research. With this experience, I would like to contribute to the "Beyond AI" project and "the PFS project, which is a new instrument of the Subaru Telescope".
