I'm interested in how the universe looks like in the early stage. In particular, I'm making an effort to detect the evidence for inflation, which is the exponential expansion of the early universe, via Cosmic Microwave Background (CMB). I take part in ground-based CMB observation experiments, the POLARBEAR and Simons Observatory.
My main topic is the developments of inner cold elements in the telescope to introduce the CMB light, and the development of the calibrator instrument to calibrate the polarization angle response of the telescope.
In apart from the CMB experiments, I work also on the search for a dark photon that can be a candidate for the cold dark matter by using millimeter-wave techniques which are used in the CMB experiments.
