I work in the field of precision observational cosmology. My science goal is to peek into the past and understand the evolutionary history of the Universe using redshifted 21cm cosmological measurements. I develope novel radio astronomy technique and build instrumentation to detect CMB spectral distortions from the early times. As an Electronics and Telecommunication Engineer, I most enjoy design and build radio telescopes while working on various aspects of optimizations, theoretical modeling, statistical RFI mitigation technique, and data analysis. I am also keenly interested in space-based redshifted 21~cm observation and my current research is laying the roadmap of future redshifted 21~cm space mission by providing the ground-based science and technological concept study.
