Peering into the cosmic dawn of the Universe gives us insight into how baryonic matter collapses into dark matter halos and forms stars. However, due to the dusty nature of star-forming regions, observations of high-z galaxies become difficult at optical to near-IR wavelengths. An ongoing James Clerk Maxwell Telescope large program, called the SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES), provides the deepest 450um data together with the more standard 850um probe. This allows us to select a set of high-z candidates and proceed with follow-up observations. In this talk, I will describe how these galaxy candidates are selected, present our work so far, and discuss our future plans.
