> By providing information on distances and proper motions for one billion stars, the Gaia satellite will allow us to investigate the major unsolved challenges in galaxy formation: the nature of dark matter, the origin of Galactic spiral activity and its relation to the bar, and more generally the history of the Milky Way. Gaia will also reveal the nature of associations of stars with coherent velocities observed in the solar neighborhood. The origin of these systems, named moving groups, remains uncertain, but their dynamics and evolution hold the key to understanding complex phenomena, such as resonances in bars and spiral arms and ultimately the dynamics of the stellar disk. My research aims to develop a theoretical approach to modeling and exploiting the big data and address problems at the forefront of Galactic Dynamics at various scales. What is the origin of the spiral activity in the Milky Way? How are all of these perturbations to the structure of the Galaxy coupled to each other directly and through the dark-matter halo?  I will also present my ongoing work on statistical techniques of big-data analysis and advanced numerical simulations used to interpret the nature of stars moving in groups and discover streams in the stellar disk of the Milky Way.
