High energy physics is another name for experimental particle physics. The goal is to reveal the ultimate nature of the building blocks of matter and the forces acting between them. On the other hand, at the beginning of the universe, subatomic particles are thought to have collided with each other with very high energy. High energy physics is recreating the phenomena at the beginning of the universe in experiments on Earth. How did the universe begin and what will happen in the future? How far will we be able to explore these ultimate mysteries?

My main research theme is to investigate the ultimate components of matter and the forces acting between them with a machine called an accelerator. At present, the Standard Model can explain most of the phenomena observed in ground-based experiments. On the other hand, we know that there is something filling the universe which is not included in the Standard Model, such as dark matter and dark energy. Our current goal is to find something beyond the Standard Model. We aim to realize the next generation accelerator facility, the International Linear Collider (ILC).  At the same time, we are working on quantum electromagnetism in a small accelerator. In addition, we are actively engaged in activities to expand the understanding of basic science and science communication.
