My main research interest is to understand the elusive dark matter and energy by analysing the large-scale structure data from current and upcoming surveys. To achieve this, I developed pipelines to analyse data from state-of-the-art surveys such as SDSS (Sloan Digital Sky Survey) and DESI (Dark Energy Spectroscopic Instrument). I focus on analysing the peculiar velocity (motion of galaxies independent of the expansion of the universe) and the galaxy power spectrum (clustering of galaxies) previously. I am also interested in extracting cosmological information from weak gravitational lensing, cosmic voids, and gravitational waves.
