Inferring characteristics of the young planet population from high resolution protoplanetary disk imaging

High angular resolution observations of protoplanetary disks at millimeter and near-infrared wavelengths have revealed an impressive variety of substructures, including gaps and rings, spiral arms, warps, and asymmetries. Models have suggested that many of these structures can be produced through planet-disk interactions. These substructures can therefore open a window into the properties of protoplanets that are below the limits of what current direct imaging technology can probe. I will review recent observations of disk substructures and how they have been used to infer the masses and orbital properties of embedded protoplanets. I will also comment on alternative interpretations of these disk substructures and what future observations will help to break degeneracies.
