Research Topic

Dark Matter Search with new astronomical observations and optical experiments

Thanks to recent developments of cosmic observation, it has been found that more than 80% of matter in our universe is composed by unknown DARK MATTER. Since Dark matter plays a central role in structure formation, an environment that human beings comfortably live would not be realized without dark matter. Combining new astronomical observations, optical experiments and theoretical research, I am exploring the nature of dark matter.
