I am primarily interested in understanding what lies beyond the Standard Model of particle physics. I am interested in pursuing novel, low-energy experiments for weakly-coupled particles that may make use of small-scale experimental techniques. The main goal is to device sensitive experiments with current technology and understand how and how much it can be improved in the future. I am interested in understanding the dynamics and observational consequences of collective phenomenon in the dark matter fluid, which leads to, for example, formation of topological defects. I am also interested in designing new searches based on astrophysical and cosmological measurements, including aLIGO, CMB, LSS and 21cm cosmology. These searches allow us to look for new physics motivated by string theory, including axions, cosmic strings, and new vacua in the landscape. I am in particularly interested in the new tool of cosmological collider, and how it might allow us to directly probe the string landscape and the multiverse.
