I am a Theoretical Physicist who is working in the branch of various theoretical developments of cosmology, application of quantum entanglement, discord and other information theoretic measures in de Sitter space, path integral approach in quantum dissipative systems in de Sitter space, cosmology with open quantum systems, application of thermalization and quantum critical quench in reheating, effective field theory techniques in cosmological perturbation theory, connection between quantum chaos and cosmology using random matrix theory, quantum chaos-complexity theory and its application to cosmology, phenomenological predictions from warped extra dimensions, cosmological model building with supergravity and string theory, various aspects of string cosmology, study of SYK and tensor-like models, and Bose–Fermi duality in Chern–Simons matter theories.
