Abstract: The evolution of galaxy merger rates and its impact on galaxy properties havebeen studied intensively over the last decade. It becomes clear now thatvarious types of mergers, i.e. gas-rich wet, gas-poor dry, or mixedmergers, affect the merger products in different ways. The epoch when each typeof merger dominates also differs. In this talk, I review the recent progress onthe measurements of galaxy merger rates out to z ~ 3 and the level ofinteraction-triggered star formation using large samples from various redshiftsurveys. These results provide insights to the importance of mergers in themass assembly history of galaxies and in the evolution of galaxy properties. Ialso present new results in characterizing the environment of galaxy mergers,and discuss their implications in the built up of red-sequence galaxies.
