Biography
I am a postdoctoral researcher at University of Turku in Finland. I have obtained my PhD degree at Kyoto University in Japan on March 2019. After this, I moved to European Southern Observatory as a JSPS Overseas Research Fellow, and spent time there until November 2020. Then, I came to University of Turku.
Research
I am working on supernovae using physics of radiation and fluid as well as using spectroscopic and polarimetric observations. "How do massive stars die?", answering this question is one of my research goals.
