Galaxy clusters are one of the largest structure in the Universe. Galaxies in such clusters undergo different history in their formation process since many mechanisms such as merging, tidal interaction, and ram pressure stripping could have affected on galaxies. Many recent studies report that the environmental effect plays an important role in galaxy evolution. Therefore, we study galaxy properties in galaxy clusters. We have developed a new method to measure more realistic local density of galaxies by using SDSS spectorscopic+photometric data. With this new method, we have found 924 galaxy clusters in the redshift range of 0.05 - 0.06. We provide the catalogue of clusters and their member candidates.
