I am an Assistant Professor at the Indian Institute of Technology-Kharagpur. My research focuses on theoretical studies of first-source formation in the Universe, methods to detect faint primordial sources, and the impact of these sources on the intergalactic medium (IGM). 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.
My Academic Timeline:
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 the 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. I also worked as a post-doctoral researcher at the University of Pennsylvania, Department of Physics & Astronomy and Haverford College from 1st September 2023 to 30th June 2024. Thereafter, I served as a Ramanujan Fellow at the Department of Physical Sciences, Indian Institute of Science Education and Research Kolkata (IISER K), before I moved to IIT Kharagpur. This fellowship was funded by the Department of Science & Technology (DST), Government of India.
