Circumstellar disks are a generic outcome of the star formation process. They preserve an historical imprint from the collapse of a molecular cloud core, play a fundamental role as accretion conduits that help set the stellar mass function, and comprise the material reservoirs used to build planets. We study many aspects of circumstellar disks using a wide variety of observational techniques, with a special focus on the analysis of radio interferometer data.
