The population of dust-obscured star-forming galaxies (DSFGs) at redshifts of z~1-5 are among the most extreme galaxies ever observed, with typical star-formation rates of 100-1000 Mo/yr. DSFGs are also estimated to contribute a significant fraction of the star-formation rate density (SFRD) at cosmic noon, making them a highly important population and providing a strong test of galaxy formation and evolution models. Advancements in instrumentation, in particular with SCUBA-2 and ALMA, have driven rapid progress in the study of DSFGs over the last decade, and we have now identified samples of hundreds of sources with which to carry out such tests. I will present a variety of observations designed to exploit these samples, with a particular focus on the molecular gas properties and kinematics, using state-of-the-art instrumentation such as ALMA and NOEMA for the former, and VLT/KMOS for the latter. I will then briefly introduce some of my work on lensed DSFGs as part of the TEMPLATES collaboration with JWST/NIRSpec.
