In the time of chimpanzees, I was a monkey...

Hey! I'm Subhodeep, a postdoctoral researcher at the Indian Institute of Technology Gandhinagar. Earlier, I was a postdoc at IIT Madras. My research focuses on strong-field probes of general relativity. I use black hole perturbation theory and numerical relativity to study gravitational collapse, quasinormal modes and ringdown physics.

More broadly, I use theoretical and computational methods to understand how gravity behaves in extreme regions of spacetime, particularly in the vicinity of black holes and exotic compact objects. Much of this work is motivated by the prospect of using gravitational waves to address fundamental questions in physics.

I am also interested in understanding the optical appearance of compact objects through gravitational lensing and black hole shadows, and the motion of particles around them. These can provide complementary and potentially observable probes of strong-field gravity. Together with gravitational waves, they may help constrain deviations from general relativity. To learn more about my work, please check out my publications.

Besides my primary research, my interests include dynamical systems and machine learning in physics. Alongside research, I enjoy teaching physics, mathematics, and programming. I have previously assisted my mentors in teaching courses like numerical methods and computational physics, biostatistics, Python programming, and classical and quantum mechanics.

I defended my Ph.D. thesis at the Indian Institute of Information Technology Allahabad in 2019, where I was mentored by Srijit Bhattacharjee. Towards the end of my doctoral studies, I was a Research Fellow at the Centre for Theoretical Physics, Jamia Millia Islamia, and worked closely with Anjan Ananda Sen. I then joined IIT Madras, where I worked with Dawood Kothawala. At IIT Gandhinagar, I work with Sudipta Sarkar. I also collaborate closely with Sumanta Chakraborty at IACS, Kolkata. You can find more about my collaborators and co-authors on my collaborations page.

I enjoy interacting and collaborating with new people, and I am always open to conversations on the topics mentioned above. Feel free to drop a line to discuss physics, exchange ideas, or discover how long it takes before one of us tries to strangle the other while writing a paper.
