Thick disks are ubiquitous in nearby spiral galaxies, and many mechanisms have been proposed to explain their formation. I will first use a suite of zoom cosmological simulations to explore the connection between a galaxy’s formation history and the structure of its disk. I will then explain our recent efforts to determine ages for a large sample of stars in the Milky Way (using APOGEE spectroscopic data combined with asteroseismology information from Kepler). I will also present new results on the structure of the Milky Way’s thick disk, and will discuss the implications for the formation history of our Galaxy.
