. ZFOURGE and ZFIRE are deep near-IR surveys that track how galaxies assemble over cosmic time. ZFOURGE identifies approximately 30,000 galaxies up to redshifts of z~7 using a custom set of medium-band near-IR filters that provide high precision photometric redshifts. ZFIRE selects galaxies from ZFOURGE for spectroscopic follow-up with Keck/MOSFIRE to measure how baryons cycle between stars, winds, and the Inter-Stellar Medium at z~2. Here I summarize our results that include stellar mass functions at 0.5 .
