Invited/Solicited talk in mini-symposium Cosmology with large-scale structure

The Dark Energy Spectroscopic Instrument (DESI) will obtain optical spectra for approximately 40 million galaxies and quasars. Using the three-dimensional distribution of these galaxies, DESI aims to measure the universe's expansion history over the past 11 billion years, thereby exploring physics of dark energy. In this talk, I will provide an overview of the DESI survey along with its latest updates. I will cover topics including the early data release, the current status of the survey, various ongoing science projects, and potential future programs within DESI. Additionally, I will discuss the planned analyses employing higher-order statistics within the DESI collaboration
