Galactic Archaeology with Stellar Spectroscopy in the Gaia Era

Whether at low- or high-redshift, one of the primary aims of modern astrophysics is to develop an understanding of the formation and evolution of galaxies. What makes the Milky Way unique is that it is the only galaxy where we can study the chemical, spatial, and kinematic distribution for large samples of resolved stars in order to achieve this goal. Different patterns in these distributions are used to define different stellar populations and studying these in detail is crucial to understand how spiral galaxies form and evolve. In this talk, I will discuss recent results from projects I have carried out focused on decomposing the various Galactic components using large spectroscopic surveys including APOGEE, SEGUE, and, Gaia-ESO to build a better understanding of the formation and assembly of our Galaxy. Additionally, I will discuss the impact that Gaia together with large spectroscopic surveys can change the way we understand our Galaxy.
