Research Interests

My research focuses on aspects of nonrelativistic quantum field theories with anisotropic scalings between space and time. I am interested in exploring the landscape of naturalness for nonrelativistic systems, with applications in condensed matter, particle physics, and gravity. Recently I am also interested in nonrelativistic string theory, whose string spectrum and spacetime S-matrix enjoy nonrelativistic symmetry.
