Research Interests

My research field is conventionally called high energy theoretical physics, or particle theory, one of the physics branches concerning fundamental particles and their interactions in the smallest microscopic world and the birth and evolution of the biggest universe, known as cosmology. My main interests are in studying the phenomena of possible new fundamental physics in laboratory detection experiments, cosmology, and colliders. The keywords are gravitational waves and dark sector. I am also interested in applications of quantum field theory and string theory.
