Exploring the universe through observations, simulations, and machine learning.

“If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.”

About Me

I am a Project Associate at Ahmedabad University, working in collaboration with SAC-ISRO on interstellar medium (ISM) filament detection and characterization using multi-wavelength dust observations of nearby star-forming regions. My work focuses on developing a quantitative methodology to extract accurate filamentary structures using multiple algorithms and to analyse their morphology and large-scale ISM environments.

I completed my BS–MS in Physics (major) and Data Science and Engineering (minor), with my master’s thesis focusing on developing score-based diffusion (VE–SDE) models for reconstructing primordial CMB B-mode polarization from upcoming observations, a direct probe of the stochastic inflationary gravitational-wave background.

My research interests span galaxy formation and evolution using multi-wavelength observations and simulations, radio astronomy and instrumentation, the epoch of reionization, 21-cm cosmology, and CMB B-mode polarization observations. I am also interested in N-body and MHD simulations, and in applying modern machine learning and AI particularly computer vision, 3D deep learning, and generative models to advance astrophysical and cosmological research.
