I report an automated method for finding and characterizing gravitationally lensed quasars in the Sloan Digital Sky Survey (SDSS). SDSS DR12 data was utilized to examine the properties of target quasars and their neighbors to determine whether these two SDSS objects were images of the same quasar. The algorithm not only identified 56 lensed quasars reported in the literature but also identified 109 new high-probability candidates.
