About me

I am working as a post-doctoral fellow at the University of Pennsylvania, Department of Physics & Astronomy. My previous academic records are as follows. I completed my B.Sc. course in 2009 from the Ramakrishna Mission Residential College, University of Calcutta, India. Thereafter I joined Harish-Chandra Research Institute (HRI), Allahabad as an integrated Ph.D. student. I completed my M.Sc. course from HRI and received a degree from Homi Bhabha National Institute (HBNI), Mumbai, India. Thereafter I moved to National Centre for Radio Astrophysics (NCRA-TIFR), Pune, India with my Ph.D. supervisor Dr. Tirthankar Roy Choudhury. I completed my Ph.D. from NCRA-TIFR in Physics in October 2016. Thereafter I joined Prof. Garrelt Mellema's group in the Department of Astronomy, Stockholm University, Sweden as a post-doctoral fellow and worked until October 2019.  Afterwards, I moved to Technion, Haifa, Israel to work with Prof. Saleem Zaroubi's group as a postdoc fellow and worked there for two years before I moved to the Open University in Ra'anana, Israel. 1st September 2023 onwards I moved to UPenn and Haverford College.

My research focuses on the theoretical studies of first source formation in the Universe, ways to detect those faint primordial sources, impacts of these sources on the intergalactic medium (IGM), etc. These primordial sources changed the ionization and thermal states of the IGM during the Cosmic Dawn and Epoch of Reionization. In other words, my research aims to probe the physical states of the Universe around 10 billion years in the past.
