STUDIES is a JCMT cosmological Large Program to obtain extremely deep 450 um images in the COSMOS field and SXDS field with more than 600 hr of observing time under the best weather on Maunakea. The goal is to obtain a representative sample of faint far-IR sources at z=0.5-3, to understand the origin of the cosmic IR background and the formation/evolution of the dusty galaxy populations. The sensitivity of the survey will be unprecedented, ~10x deeper than the deepest Herschel SPIRE imaging and offering the deepest far-IR selection of high-redshift galaxies. Here I will present the current status of the program and some recent results, including 450 um counts, source redshift distribution, morphology, and a case study on a z=3.7 "passive" galaxy. We welcome Taiwanese astronomers to join our program and to conduct SMA, ALMA, and other multi-wavelength follow-up observations.
