I have been pursuing the research on the physics of early universe using the measurement of the cosmic microwave background (CMB) polarization. Currently, the measurement of the CMB polarization is known as a powerful tool to test inflationary models. While working on a CMB experiment is fascinating in terms of the scientific goal itself it is also exciting in terms of the nature of the experiment. A CMB experiment requires using broad areas of physics. It starts from relativistic cosmology to astronomy, thermal statistics, optics, superconductivity, mechanics, electromagnetism, and so on. Also the experimental techniques come with as simple as soldering wires (not actually simple!) to cryogenics, mechanical design and machining, parallel computing, and more. This makes me feel a tight connection between daily activities and an event at the early universe, which may always look as if it is unreachable. The Kavli IPMU is a hub for scientists who are inspired by the fundamental questions and I look forward to working with you at the Kavli IPMU.
