Supersymmetry is fascinating. Not only because it is symmetry possessed by string theory, but also because there are many phenomenologically attractive features in supersymmetric models. Discoveries are also expected at the Large Hadron Collider.

The 1990s brought a revolution, which gives us a technique to control a strongly coupled theory. In a strongly coupled region, it is believed that rich physics should exist. I am very interested in applying this progress to realistic model building and to the understanding of confinement in QCD.
