Observational searches for dual active galactic nuclei (AGNs) at kiloparsec separations are crucial for understanding the role of galaxy mergers in the evolution of galaxies. In addition, kiloparsec-scale dual AGNs are the parent population of merging massive black hole (MBH) binaries. In this talk, I will describe our recent efforts to quantify the observational properties of dual AGNs that are most likely to result in MBH mergers and the emission of gravitational waves. I will also discuss how dual AGNs can be used to constrain the cosmological MBH coalescence rate and make predictions for the detection rate of the future gravitational wave detector LISA.
