I am a second year PhD student at Indian Institute of Science, working under the supervision of Professor Rajeev Jain. My research is primarily focused on phenomenology of non-Gaussian signals arising from cosmological collider physics. My current project focuses on understanding the non-Gaussian signals of gauge fields during inflation by computing the bi-spectrum and tri-spectrum produced by the exchange of a massive scalar. I am also deeply interested in the Cosmological Bootstrap program and the holography of de Sitter space-times. During my Master’s degree, I worked on aspects of the holographic principle and Ryu-Takayanagi surfaces in AdS and Minkowski geometries. At present, I am actively engaging with the Open Effective Field Theory approach to inflation, aiming to broaden the theoretical toolkit for understanding the early universe.
