Galaxy groups are environments in which galaxies are expected to interact significantly which influences their star formation, morphology and AGN activities. We study the impact of group dynamics on the evolution of galaxies in an attempt to understand the halo-galaxy connection. I will describe our decade-long project involving observational studies and cosmological simulations and review their outcomes with a focus on the AGN activity in the most massive galaxies in galaxy groups and show that their activity is influenced by the environment.
