Thanks to ALMA, the study of protoplanetary disks is undergoing a revolution, with a wide variety of results being reported on statistics of disks and fascinating substructures in dust and gas that point to planet formation in action. This talk will present an overview of results from our group and collaborators on observations and models of disks. Highlights include statistics on disk masses, from low to high-mass regions and young to more evolved disks, indicating that planet formation must start early. The surprisingly weak CO emission and consequences for C/O ratios in gas and ice will be discussed. Special attention will be given to transitional disks with large cavities, which are the best candidate sources for harboring just-formed giant planets. Prospects for linking outer and inner disk structure with JWST will be presented.
