The perturbative methods have been quite successful in quantum field theory, for example when explaining the experimental data such as scattering cross sections. However the non-perturbative side of the quantum field theory is equally important, if not more, since it tells us the non-local properties of the theory. I am interested in studying the non-perturbative properties of quantum field theory in various dimensions, including but no limited to the non-trivial topological solution to the equation of motion, i.e. solitons and their quantum effects.
