I am a project assistant professor (NAOJ fellow) at National Astronomical Observatory of Japan (NAOJ) in Japan. I am working on supernovae using physics of radiation and fluid as well as using spectroscopic and polarimetric observations. Supernovae are important objects in the history of the Universe. They are related not only to stellar death but also to stellar birth and evolution. Unlike the most phenomena in the Universe, supernovae happen in the time scale of humans such as ~100 days, which enables us to, as a reality, feel the energy of the Universe and the fact that the Universe is changing. “We can understand phenomena that seem to be impossible to be understood, using human brains (physics). Moreover, such amazing phenomena beyond our imagination are real”. These facts brought me to the world of astrophysics. I would like to join “the ultimate intellectual game”, i.e., a game to solve mysteries of the Universe using various types of hints given by the Universe. I hope to be like researchers around me, who can understand the essential physics for a wide range of phenomena, just using blackboard calculations. Except playing with the Universe, my hobbies are traveling, walking in nature, collecting stones, playing sports (baseball, skiing, swimming), cooking and adventures.<\/p>
