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 measure in de Sitter space, Path integral approach in quantum dissipative system 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, 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, Bose Fermi duality in Chern Simons matter theories.
I have completed my BSc in Physics at Scottish Church College, Kolkata, India in 2007, followed by a MSc in Physics at the University of Calcutta, Kolkata, India. In my undergraduate career, I have carried out short project in Phase transition in Ising model. Starting from September 2009, I have joined as a PhD student at Physics and Applied mathematics Unit, Indian Statistical Institute, Kolkata, India and got the PhD degree on March 2016. Further I have joined as a Post Doctoral Fellow at String Theory and Mathematical Physics Group, Theoretical Physics department, Tata Institute of Fundamental Research, Mumbai, India on February 2015 and continued up to October 2017. After that I have joined as a Post Doctoral Fellow at Inter University Centre for Astronomy and Astrophysics, Pune, India on end of October 2017 and continued there up to March 2018. After that on March 2018 I have joined as a Post Doctoral Fellow at Theoretical Cosmology Group, Max Planck Institute for Gravitational Physics, Albert Einstein Institute, Potsdam.
