Research Interests

My research interest is to understand quantum field theory, string theory and their powerful applications to theoretical physics and mathematics. In particular I have been studying dualities in supersymmetric gauge theory with boundaries and corners which can elucidate rich mathematical structure of quantum field theories as well as description of intersecting D-branes and M-branes in string and M-theory.
