Size is a fundamental parameter in our understanding of galaxy formation. The first galaxies- small, low mass disks grow to the large, structured galaxies of the present day through repeated mergers. Observations of large, massive disk galaxies at redshifts between 1.5 and 3 pose an interesting challenge to the hierarchical picture. The FIRES survey tep{labbe} reveals that these galaxies have sizes comparable (or possibly larger) than the Milky Way. How did mass assemble into such large galaxies only 2-3 Gyr after the Big Bang? In this project, we aim to characterize the dynamical state of these large disks. Here, we present our preliminary results- using near infrared spectroscopic data from the 8-m Gemini South Telescope, we discuss aspects of star formation and the followup work we have planned for these objects.
