Studies of luminous and ultraluminous infrared galaxies at high redshift provide a fundamental insight into the role of galaxy mergers, starbursts, and active galactic nuclei in galaxy evolution. One of the difficulties in studying the properties of these objects at high redshift is the lack of spectrocopic data for large samples. Spectroscopy is crucial, not only for a redshift determination and an accurate estimate of the total infrared luminosity, but also for studying the starburst-AGN connection. Here, we present the results of our optical and near-infrared spectroscopic survey of 24 micron selected galaxies in a deep test area of the COSMOS field conducted with DEIMOS on Keck II and MOIRCS on Subaru. With this sample, we study the starburst-AGN connection for infrared galaxies across a wide redshift range (0.1 < z < 2) as a function of total infrared luminosity and morphology.
