Future Prospects
Surveys of ~ 1000’s galaxies with multi-IFUs and MOS (e.g., KMOS, MUSE, MOSFIRE) Surveys of ~ 100+ with IRAM/NOEMA and ALMA
Synergies w/ HST, AO, and local surveys (CALIFA, SAMI, MANGA, …)
More complete and coherent picture over cosmic time combining detailed and global properties of galaxies
