Abstract　 　　  

   According to the recent Planck results, our current universe is composed of about 25% dark matter, 70% dark energy and less than 5% baryon matter. It is one of the main interest to study the properties of the dark matter from the galaxy distributions that we observe. In this talk, I'll introduce my work in the past few years focusing on the efforts to understand the underlying dark matter from the galaxy clustering properties using the large-scale galaxy surveys. My work includes both the measurements from observation and the theories to build up the relation between galaxies and the dark matter halos. We currently have a very reasonable model to help us understand the galaxy formation and evolution and also constrain the cosmology.​
