Non-perturbative approaches to quantum field theory and superstring theory

• Lattice formulation of chiral gauge theories
• Numerical study of superstring theory on the basis of lattice field theory
• Gradient flow method (especially, its relation with renormalization group)
• "Pathology" of perturbation theory and resurgence theory: renormalon problem
• Lattice implementation of generalized symmetry and anomaly matching
