I am a Postdoctoral research scholar in the Department of Astrophysical Sciences at Princeton University and a Member (Postdoctoral Fellow) in Astrophysics in the School of Natural Sciences at the Institute for Advanced Study, Princeton.
I did my PhD in Astrophysics under the supervision of Prof. Frank C. van den Bosch in the Department of Astronomy at Yale University. My primary research areas include galactic dynamics, dark matter and the kinetic theory of collisionless and weakly collisional systems. I develop perturbative and non-perturbative theories for the response of self-gravitating, collisionless systems like galaxies and cold dark matter halos to external perturbations, e.g., gravitational encounters. I also study the role of secular processes like dynamical friction and relaxation/equilibration processes like phase mixing, Landau damping, resonant relaxation, violent relaxation, chaotic mixing, etc. in galaxy evolution. One of the major goals of my work is to constrain dark matter models (is dark matter cold, warm, self-interacting or fuzzy?) using dynamics in galactic and sub-galactic scales.
I hail from the city of Kolkata (The City of Joy), India. I did my Bachelors of Science in Physics from the Indian Institute of Technology Kanpur (IITK).
Besides science, I am interested in travel, philosophy, science fiction and music. I love spending time amidst Nature, going on mountain treks (especially the majestic Himalayas) and forest hikes (tropical rainforests). Ruins of ancient civilizations and sites of historical importance appeal to me. I take great interest in the philosophies of the ancient eastern schools of thought such as the Tibetan School of Mahayana Buddhism and the Taoist School of ancient China. I love reading science fiction novels and watching movies based on philosophical science fiction (latest favorite: Interstellar). I sing Hindustani Classical Music and play the harmonium. In my alone times, I love to get lost in the blissful world of music.
