I have been researching the variable objects (mainly transients) in multiple wavelengths. My interest is to derive a physical description of them from light curves and spectra.

I have examined the origin and geometric description of gamma-ray bursts and neutron stars using a time series of X-ray spectra. In the meanwhile, I have developed and operated optical instruments for examining GRB afterglow and supernovas.

At Kavli IPMU, I will research transients such as supernovae using Subaru/HSC data, and visualize the big data of Subaru/HSC.
