I am an astronomer in the Department of Astronomy, Kyoto University. My research focuses on astrophysical explosive and transient phenomena in the Universe, including supernovae, gamma-ray bursts, and various kinds of enigmatic events. I also work for related topics, such as stellar evolution, the origin(s) of matter in different formats (elements, cosmic rays, dust particles), and observational cosmology. I investigate the physics of these exciting phenomena through both theoretical and observational studies.

​

The theoretical research adopts various different approaches, covering both analytical work and intensive supercomputing simulations. The physical processes which I mainly consider are the following: hydrodynamics, nuclear reactions and nucleosynthesis, radiation transfer, and stellar evolution. On the observational side, I have been conducting multi-wavelength follow-up observations of supernovae and extragalactic transients. I use various telescopes around the world, including the 3.8m Seimei Telescope of Kyoto University, the Subaru, ALMA, Chandra, among others. Combining the theoretical approaches and the broad-band/multi-mode observations, I am exploring the nature and origin of the high-energy phenomena from various perspectives.
